Dry Suit Accessories
How do I attach my Halcyon pocket to my wet or dry suit?
Necessary Tools: chalk, small brush, small rollerRecommended Adhesive: McNett Seal Cement
- Don suit and hold pocket in desired location. (Recommended placement is on outerthigh to keep the pockets out of the flow.)
- Use chalk to outline the desired location for pocket.
- Remove suit and place on a hard, flat surface.
- Apply first coat of Seal Cement around outer one-inch strip on both the suit and the pocket.
- Allow the adhesive to get tacky for about ten minutes and then apply a second coat.
- Allow the second coat to dry until tacky, again for about ten minutes, and then apply a third coat.
- Again allow the adhesive to dry until tacky, about ten minutes.
- Place the pocket on the suit in the exact location desired. (Make sure it’s correct since it will not move easily at this point.)
- Use the roller to roll the pocket on the suit.
- Allow the suit and pocket to dry for at least 24 hours before diving.
How do I select my size of Halcyon Gaiters?

How do I select a size for Halcyon Springheels?
Spring straps can also be sized quickly and simply. Wear your bootie (dry suit or wetsuit) and place the foot into the fin pocket. Measure the distance from pin to pin behind the heel to select the appropriate size. Typically, if you are between sizes, it’s best to go down a size, unless you are sensitive about a too-snug strap. Other sizing strategies suggested by our top dealers are available; please let us know if you’d like more details.
Medium: 8inch
Large: 10inch
What are E/O cords (underwater pluggable cords) and how are they used?
Halcyon E/O cords are versatile, underwater pluggable connectors and are standard equipment on the Apollo line of underwater film and video lighting; they are also available as an upgrade on all Explorer lighting systems. Slender two-pin connectors allow the user to disconnect the camera, housing, and light heads from our waist-mounted, high-capacity NiMH battery pack. This often-overlooked feature is highly prized by underwater filmmakers returning to the stern ladder in heavy seas, clamoring up the steep sides of a sinkhole, or seeking to switch between video and conventional light heads. E/O cords also allow divers to carry a back-up light head and switch while underwater.
Divers often ask how the term E/O was derived. E/O was the name used for these fittings when they were first manufactured by Electro-Oceanic, Inc. Over the years, through mergers and buy-outs, Electro-Oceanic has disappeared from the business landscape. Now in the fourth generation of the design, the term E/O is still associated with this connector, but we now refer to them as underwater pluggable cords.
What is the difference between HID and LED lighting?
Understanding HID Lighting
High Intensity Discharge (HID) lighting replaces the filament of a light bulb with a capsule of gas. The light emanates from an arc discharge between two closely spaced electrodes. This discharge is hermetically sealed inside a small quartz glass tubular capsule. HID lights require a ballast, which carefully regulates the voltage supplied to the capsule of gas. The amount of light produced is greater than a standard halogen bulb while consuming less power; this light more closely approximates the colour temperature of natural daylight.
In all High Intensity Discharge lamps, light is produced by passing a current through a metal vapour. Free electrons colliding with an atom in the vapour momentarily knock an electron into a higher orbit of the atom. When the displaced electron falls back to its former level, a quantum of radiation is emitted. The wavelength of radiation depends on the energy zone of the disturbed electron and on the type of metal vapour used in the arc tube.
HID bulbs produce 5 percent of their output when first ignited, requiring a few seconds (usually 15-20) to reach full output. Also, if power to the lamp is lost or turned off, the arc tube must cool before the arc can be re-struck and light produced. Halcyon HID lights require approximately 5-10 seconds before they can be re-lit.
Understanding LED Lighting
Light-Emitting Diodes (LED) are light sources utilizing diodes that emit light when connected in a circuit. The effect is a form of electroluminescence where LEDs release a large number of photons outward; the LED is housed in a plastic bulb, which concentrates the light source.
The most important part of an LED is the semi-conductor chip located in the centre of the light source. The chip has two regions separated by a junction. The p region is dominated by positive electric charges and the n region is dominated by negative electric charges. The junction acts as a barrier to the flow of electrons between the p and the n regions. When sufficient voltage is applied to the semi-conductor chip, the electrons are able to cross the junction into the p region.
When sufficient voltage is applied to the semi-conductor chip, electrons can move easily across the junction where they are immediately attracted to the positive forces in the p region. When an electron moves sufficiently close to a positive charge in the p region, the two charges “re-combine.“
Each time an electron recombines with a positive charge, electric potential energy is converted into electromagnetic energy. For each recombination of a negative and a positive charge, a quantum of electromagnetic energy is emitted in the form of a photon of light. This photon has a frequency determined by the characteristics of the semiconductor material (usually a combination of the chemical elements gallium, arsenic, and phosphorus). LEDs that emit different colors are made of different semiconductor materials. Said simply, LEDs are tiny “bulbs” fit into an electrical circuit. However, unlike ordinary incandescent bulbs, they don’t have a filament. LEDs are illuminated solely by the movement of electrons in a semiconductor material, making them energy efficient and extremely resilient over long periods of time.
LED Advantages
LEDs don’t have a filament to burn out or break; therefore, they last much longer than conventional bulbs. Given that a very small semiconductor chip runs an LED, they are very durable and tend to last many thousands of hours. Moreover, LEDs are “instant on,” much like halogen lamps, and thus convenient for use in applications that are subject to frequent or potential on-off cycling. Conversely, HID lamps are more fragile and have to warm up (15 – 25 seconds) during ignition. However, HID lights are much brighter than current LED configurations. This is because the side-emitting light found with HIDs is much easier to focus; the front-emitting nature of LEDs does not lend itself to a tightly focused beam. HID lighting is still preferred by most divers given the superior intensity and tight focus. However, LED technology is changing rapidly and it is foreseeable that LEDs will eventually surpass the performance of HID lighting.

What HID bulb is used by Halcyon?
Two primary manufacturers produce bulbs suitable for the demands of Halcyon underwater lights. Welch Allyn is a very large manufacturer, producing a range of medical devices including HID lighting. Historically, these bulbs were superior to any competitive products. Approximately five years ago, Halcyon was one of the very first to receive samples from an auto parts company (Bright Star) forging into underwater lighting technology. These initial samples showed promise but were inferior in terms of reliability as well as the quality of light output. However, Halcyon remained in communication with Bright Star, continuously evaluating the newest iterations of their HID components. After five years of continual improvement, we are confident that Bright Star represents the best value in the 21-watt segment of the Halcyon product line. Our 10-watt HID lighting is still produced by Welch Allyn and we continue working with both companies while evaluating ongoing technology innovations.
What is a locking bulb design?
HID lighting requires a constant supply of current. A ballast regulates current to the HID bulb. Any interruption causes the bulb to lose ignition, requiring that the ballast be reset. Resetting the ballast requires turning off the light and waiting five seconds before reigniting the bulb. Over the years, Halcyon has worked tirelessly to reduce the risk of current interruption, incorporating a range of unique features. One such feature is our use of an industry-first sealed lid design, containing gold-plated connectors (to ensure a solid, reliable connection). The recent innovation of a locking bulb design uses a proprietary design in which the Halcyon bulb is retained by a treaded locking collar. The unique design allows easy bulb installation but prevents the bulb from working free from the socket. Our competitor’s lights do not incorporate this feature, allowing the bulb to be dislodged during transport or while entering the water before diving. The locking-bulb design is one of many Halcyon innovations designed to ensure unmatched reliability.
Why is PEEK a better material for a bulb socket?
Light output generates energy, which is discharged in the form of heat. This heat is most intense near the bulb. Therefore, materials near the lamp must be able to withstand high temperatures. A quick evaluation of other lights in the industry will reveal the obvious signs of melting that occur at the bulb and socket interface. Therefore, Halcyon chose an expensive material known as PEEK (Poly Ether Ether Ketone). PEEK maintains a very high temperature range (melting temperature of 644 degrees Fahrenheit), insulating the socket against the damage of high temperatures found near the HID bulb.
Will Halcyon continue to offer replacement parts for my existing Halcyon light?
Yes, Halcyon will continue to support repairs and parts for Halcyon products using Welch Allen lighting. Field repair kits as well as spare bulbs will remain available from your Halcyon Authorised Dealer.
Which light is best for wreck/cave/open water/photography?
Halcyon’s video lighting systems can meet the needs of every diver, from the recreational reef seeker to the professional filmmaker. When selecting your Halcyon lighting product, you need to take into consideration the length of your dives, the environment you will be diving in, and any specific tasks that would require a particular quantity or quality of lighting.
HID and HMI lighting have had a revolutionary impact on underwater film and video illumination. These technologies offer greatly extended burn times over equivalent intensity halogen lighting. Divers can easily power high-intensity HID lights from a small hip-mounted canister battery or from camera-mounted high-intensity battery packs. Meanwhile, the notably enhanced intensity of HMI lighting requires a larger battery pack. HID and HMI lighting provide much improved colour temperature over halogen, approaching the colour temperature of sunlight. HID and HMI technologies are very similar, though the greater intensity of HMI together with its enhanced and more consistent colour temperature make it a favourite among professional videographers.
With respect to HID technology, individuals may choose from entry-level single and dual 21-watt HID light heads. Meanwhile, single or dual 50-watt HID light heads are the preferred lights for serious amateurs or seasoned professionals. Meanwhile, the Halcyon 200-watt HMI is a favourite among professional videographers seeking the ultimate in portable, high-quality underwater lighting.

What is the difference between the Scout and other C-cell lights on the market?
Attention to detail and purposeful design helped define the Halcyon Scout light as a trend-setting hand-held lighting product. A focused, high power LED model, together with a powerful Halogen version, allow divers to choose the light that best meets their needs. The rugged and bright Scout is small and dependable with an easy-to-use, low-maintenance design.
The Scout’s battery-matched voltage prevents halogen bulb strain common to other designs. Meanwhile, our high power LED offers 50 percent more output over previous LED models; yet burn time exceeds 30 hours of total burn time. The twist-activated light eliminates the risk of switch failure and accidental ignition. Meanwhile, a carefully constructed body is machined from a solid piece of Delrin with a proprietary raised finish, ensuring easy activation even while wearing gloves. The sturdy Delrin body uses a single O-ring, further reducing unnecessary failure points with a simple design that allows for easy maintenance and convenient service. However, given the extreme durability of the Scout light, damage is virtually unknown. Even the Scout’s clear bezel is custom machined out of high-quality Lexan material. The streamlined form factor holds three in-line batteries and tucks neatly out of the way.

What do I do if my light floods?
Halcyon has spent years refining its lighting systems to make them as rugged as possible. Despite our best efforts, light cords can be smashed by rolling tanks and O-rings can be damaged. Regardless of the cause, a flooded light can create great anxiety. Our Tech Services experts have assembled a list of instructions outlining the management of a flooded light. Please see the following suggestions and contact a Halcyon staff member if you have any questions.
Return all components (including charger) to your Halcyon dealer for repair. If you do not have a local dealer, you can contact Halcyon’s tech services department directly via email for instructions on returning the light to the factory.
Halcyon’s webbing slot angles have been designed to provide optimal comfort for the diver. During a dive, webbing slip is mitigated by the inherent grip of the slot on the webbing, enhancing diver performance and comfort. Halcyon webbing is manufactured exclusively to Halcyon specifications; our webbing is stiff enough to provide support but soft enough to allow a complete range of motion. The crotch strap features 2” soft webbing carefully selected to minimize wear points and prevent uncomfortable pressure points.
Given that most divers would prefer to be more than just neutral at the surface, it is recommended that all divers double their variable buoyancy requirement to determine their minimum lift BC wing. In this case, the required buoyancy would be 30lb. (13.6 kg) of lift.
There are a few other factors that can increase your lift requirements. One is a desire for your BC to float your gear without you in it. It is not necessarily a requirement, but it can be of benefit—particularly for divers who dive out of an inflatable or don their gear in the water. Determine this lift requirement by adding together the lift needed to float the specific tank uses and how much weight is on the system.
As with any change in one’s diving equipment, it is recommended that all divers make a few dives with their buddy, in controlled conditions, to determine how that change will affect the in-water performance, before returning to their normal diving regimen.
Careful wing selection will ensure adequate lift capacity to meet your diving needs, while avoiding excessive amounts of lift capacity—decreasing drag and effort expended and increasing effectiveness.
- Remove the battery from the canister and dry it as much as possible.
- Even if the flood was in salt water, do not rinse off any component with fresh water—it will only cause further damage.
- Remove the bulb and gently towel dry.
- Dry the underside of the lid.
- With the 10-watt HID, remove the front glass lens and the bulb and dry all external surfaces.
- Dry off the inside of the canister.
- Do not disassemble the unit other than the bulb removal.
- Keep the battery separate from the rest of the components—specifically with saltwater damage, do not put a previously flooded battery into the canister and latch the lid.
Return all components (including charger) to your Halcyon dealer for repair. If you do not have a local dealer, you can contact Halcyon’s tech services department directly via email for instructions on returning the light to the factory.
What makes a Halcyon backplate so unique?
Every Halcyon backplate features a host of subtle finishing details that enhance in-water performance, reliability, and diving comfort. These factors, together with the industry’s highest quality finish, set Halcyon backplates apart from the ordinary. Available in carefully finished Stainless Steel or mil.spec. hard-coated aluminium, the Halcyon backplate resists the oxidation and marring common in other less finished, yet similarly priced, plates. Individually milled edges combine with the high quality materials to provide the industry’s most sought-after backplate. In addition to our unparalleled quality and unique ergonomic shaping, each Halcyon backplate features attachment points for Halcyon’s Single-tank Adapter, Storage Pak, ACB Weight Pockets and the low profile (6 ft3) dry suit inflation bottle mounting straps.Halcyon’s webbing slot angles have been designed to provide optimal comfort for the diver.

BC System Weighting
- Appropriate distribution of a diver’s ballast is a key ingredient to proper trim and efficient buoyancy control. Traditionally, divers have been taught to place all their ballast on the familiar two-inch waist belt. However, this strategy pulls a diver’s legs down, increasing drag and reducing diving comfort. The wide diversity of Halcyon weighting options allows divers to easily partition weight, supporting optimal balance and reducing diver effort. These unique options notably enhance a diver’s in-water balance, enhancing comfort and diving fun.
- Choice of backplate: Stainless Steel 6 lb. (2.7 kg) or light-weight hard-coat aluminium
- ACB Weight Pockets: available in 12-lb. (5.4 kg) and 20-lb. (9 kg) systems
- Standard and Convertible Single-tank Mount (STA): up to 6 lb. (2.7 kg)
- Trim Weight Pockets (pair):up to 5 lb. (2.2 kg) per pocket
- V-weight:8 lb. (3.6 kg) or 11 lb. (4.9 kg) for dual-cylinder diving
Can I balance “non-releasable “and “releasable“ weighting on my Halcyon BC System?
Halcyon diving systems allow convenient distribution of a diver’s weight in a way that supports diving safety and enhanced diving comfort. Divers can easily mix ditchable and non-ditchable ballast to allow easy removal of a portion of a diver’s weight. For example, this weight might be placed in Halcyon’s patented ACB pockets; these weights can be removed during an emergency or as a means to easily egress from the water.How do I determine the required lift capacity of my Halcyon buoyancy compensator?
To determine the required lift capacity of your Halcyon buoyancy compensator, it is necessary to cover the basic concepts relating to proper weighting. Proper weighting requires a diver to be able to maintain a safety or deco stop at 10ft/3m with only 500psi (35 BAR) in the tank. If you can’t maintain neutral buoyancy, adjust weight accordingly. Avoid the temptation to over-weight. Over-weighting requires excess lift, while increasing drag and instability. Moreover, this excess weight is problematic in the event that the diver must swim up from depth. The required lift has little to do with the amount of weight divers are wearing, but instead is tied to their variable buoyancy. Divers’ variable buoyancy is determined by the weight of the gas in their tank plus the loss of buoyancy from their wetsuit (or neoprene drysuit) due to compression at depth. Divers wearing a tri-laminate (shell-type) or crushed neoprene drysuit do not experience such compression, making this calculation even easier. The average ¼-inch (approx. 5 mm) wetsuit looses about 9lb. (4 kg) of buoyancy at 100ft (30 m); 80CF of air from a typical Al-80 weighs 6lbs (2.7 kg), so with an Al-80 tank and a ¼-inch (5 mm) wetsuit, the variation in buoyancy from the start of the dive (at depth with a full tank) to the end of the dive (at 10ft/3m with 500psi/35 BAR) will be 15lb. (6.8 kg).Having weighted to be neutral at the end of the dive, the gas equivalent to15 lb. (6.8 kg) of lift will need to be added to the BC at the start of the dive (at depth) to be neutral.Given that most divers would prefer to be more than just neutral at the surface, it is recommended that all divers double their variable buoyancy requirement to determine their minimum lift BC wing. In this case, the required buoyancy would be 30lb. (13.6 kg) of lift.
There are a few other factors that can increase your lift requirements. One is a desire for your BC to float your gear without you in it. It is not necessarily a requirement, but it can be of benefit—particularly for divers who dive out of an inflatable or don their gear in the water. Determine this lift requirement by adding together the lift needed to float the specific tank uses and how much weight is on the system.
As with any change in one’s diving equipment, it is recommended that all divers make a few dives with their buddy, in controlled conditions, to determine how that change will affect the in-water performance, before returning to their normal diving regimen.
Careful wing selection will ensure adequate lift capacity to meet your diving needs, while avoiding excessive amounts of lift capacity—decreasing drag and effort expended and increasing effectiveness.
Can back-mounted wings provide safe buoyancy on the surface of the water?
The question of surface buoyancy is almost exclusively related to the buoyancy of the diving cylinder. This is true regardless of the style of the BC. For example, our experience in testing a wide range of BC designs shows that the conventional “jacket” style of BCs are greatly affected by the buoyancy of the diving cylinder used. These BCs produce a face-down or side-high surface position with a buoyant tank attached. In order to counteract this effect, divers may use a Halcyon trim weight pocket to counteract the positive force of a buoyant cylinder.Is the Halcyon BC system appropriate for recreational open-water diving?
Halcyon is one of the world’s most established technical diving brands. However, it is a little-known fact that the majority of Halcyon owners are recreational divers. The Halcyon BC is less cluttered and less restrictive than jacket-style BCs while providing a perfectly tailored fit. This system also creates far less drag in the water and is more stable than conventional jacket-style BCs. These factors reduce diving effort while increasing efficiency and diving fun.
If you are having problems fitting your weights in the ACB pocket, we suggest that you wet the pocket to allow the nylon to stretch as you load the pocket. Even if the weights fit the pocket when dry, we recommend that you wet the weight pouch when inserting weights for the same reason you should wet the nylon cam straps to hold your tanks– by making sure that the weights have a secure fit when the pocket is wet, you lessen the possibility that the weight could be dislodged during a dive.
Do I have to use an ACB integrated weight system, or can I use a weight belt?
Do I have to use an ACB integrated weight system, or can I use a weight belt?
The traditional weight belt works with any Halcyon BC system. However, for divers seeking maximum safety and efficiency in their gear configuration, the ACB Weight Pockets provide a sleek, low profile—and more comfortable—alternative to the standard weight belt. Both the 12-lb. and 20-lb. styles feature a unique design that eliminates the use of “all-or-nothing“ style weight releases. ACB users can remove one or both weight pockets for greater control or to ease boat entry.
How is the integrated weight system attached to the Secure Harness?
To secure your Halcyon ACB to the 2” webbing of your Halcyon Secure Harness, the webbing must pass through the tri-glide twice. Starting with the left side ACB pocket (with the D-ring), looking from the side that rests against the diver’s body, route the waist belt webbing up through the first open slot on the tri-glide. Slide the ACB pocket along the 2” webbing until it is snug against the back plate. Then feed the webbing back down through the second slot of the tri-glide (where the thin mil-spec webbing secures the tri-glide to the ACB pocket). The waist belt webbing then slips easily into the “belt loop” channel stitched into the back (diver side) of the ACB pocket. Depending on the size of the diver and the desired position, some adjustment of the final ACB position may be required.How do I attach my Halcyon canister light when using an ACB system?
Slide your Halcyon Explorer or Proteus light onto the right side of the waist belt and against your Stainless Steel or hard-coated aluminium backplate. Your light canister will then be followed by the right-hand ACB pocket and affixed properly via the tri-glide and waist belt slot.Trim Weights
The Halcyon Trim Weight Pocket allows Halcyon divers to move up to 10 lb. (5 lb. per pocket maximum) from their waist belt or Halcyon ACB system to the cylinder. Each pocket is constructed from 1000-denier ballistic nylon with Velcro closure reinforced by a quick-release buckle. Moving weight from a diver’s waist can improve horizontal trim, leading to more efficient propulsion, lower gas consumption, increased bottom time, and greater enjoyment of the dive. Trim weight pockets also counteract the positive weight of near-empty cylinders. By counteracting this positive ballast, the trim weight pocket also encourages a head-up position at the surface.
BC sizing relates to using the appropriate BC (single or double tank) and also to using the proper amount of lift required. Single-tank divers requiring very little lift (such as those diving warm water) do not require large BCs with high lift capacity. A large air cell causes gas in the wing to shift dramatically, leaving the diver struggling to regain stability instead of relaxing to enjoy the dive. Using the right tool for the job allows divers to enjoy their time below the surface. As one’s comfort level increases and the stress of struggling with awkward equipment is reduced, you will find properly fitted dive gear should “disappear,” leaving you to enjoy your time in the water.
The proven Explorer series wing provides an ideal choice for divers seeking a traditional horseshoe-shaped doubles wing. The rugged, RF-welded nylon/urethane air cell is protected by an exterior ballistic nylon cover and offers the utmost in performance and reliability. The union of these two materials produces a very supple wing with excellent abrasion resistance for the outside shell and excellent puncture protection for the interior bladder. The industry-leading Explorer wing has a range of exploration-proven design features:
Evolve
The Halcyon Evolve is based on the successful circular air cell popularized by Halcyon Eclipse BCs. The Evolve’s shape is the culmination of a rigorous three-year testing period during which Halcyon tested a range of design iterations. The Evolve features the same proven materials and construction available in the time-tested Explorer BC systems. In addition to eliminating the potential for gas trapping on one side of the air cell, the circular design provides trim-enhancing lift at the base of the cylinders. In addition to precise diver control, the Evolve presents a lower profile due to the even distribution of the lift gas throughout the air cell. While using the Evolve, divers can enjoy the following features:
Evolve or Explorer as Single Tank Wing
I want to use my double-tank wing on a single tank. Can I use my double- and single-tank BCs interchangeably?
Halcyon BCs are carefully designed to minimize drag and maximize in-water stability. This superior function depends partly upon diving the appropriate-sized BC. For example, diving an Evolve double-tank BC on a single tank will be inefficient, reducing stability and increasing drag. This is because the BC is not sized for this application and will not fit the scuba unit properly. Unfortunately, the one-size-fits-all idea is common in the industry, leading divers to devalue a proper fit. BC systems that are oversized are significantly inferior in function to those that are sized properly.BC sizing relates to using the appropriate BC (single or double tank) and also to using the proper amount of lift required.

Selecting Utility Pockets for Your Dive System
We often receive email from divers excited about their upcoming diving adventures. Some of these divers want to know the best way to store a variety of Halcyon accessories without negatively affecting the performance of their Halcyon system. Halcyon offers several carefully considered methods for storing diving accessories.

The right-hand pocket provides an ideal storage compartment; divers breathing a long-hose primary also enjoy this pocket as a convenient place to secure the long hose. Designed to provide stowage for spools, surface markers, and other incidentals, this semi-rigid pocket mounts on the right side of the waist belt. Although both the right-hand zipper pocket and the ACB pocket allow for the addition of a canister light, they do occupy space on the waist belt. Some divers will find it difficult to mount a pocket and ACB or light to the same location.Suit-mounted Pockets
Many divers prefer to add additional storage to the dive suit. Halcyon offers two sizes of Bellow pockets that can be sewn or glued to the side of the diver’s thigh. The pockets come in a Standard or Exploration (BAP) size. Both pockets possess a range of features, including:- Internal divider for stowing the Halcyon Diver’s Notebook
- Large compartment for spare parts, double enders, line arrows etc.
- Rapid-drain mesh lining for easy venting
- Flexible loops to secure stowed items
- Pocket flap with built-in accessory pocket
Understanding Wing Material
How does Halcyon select its material used in building its wings?
Here are a few suggestions that will improve efficiency while working with the Halcyon Storage Pak.
Diver Alert Markers
The easiest of the markers to stow, various DAMs are simply folded accordion-style with the length of each fold just short of the full length of the BC Storage Pak. The bottom (foundation) fold should include the black nylon tail and Stainless Steel clip, which routes out of the open bottom of the BC Pak and clips to either the rear or left-hip D-ring.
Lift Bags and Diver’s Life Raft
In order to stow a liftbag or raft, the wider designs require symmetrical folds along the length of each side. The goal is to create an overall width slightly smaller than the opening in the BC Pak. Once this is achieved, simply make a few accordion-style folds, again leaving the tail available to be clipped to the rear or left-hip D-ring. Once successfully within the Pak, try on the harness and backplate. If the Pak is not fitting comfortably, you can adjust the position of the dump or inlet valves to a more central position in the channel of the backplate. The BC Pak’s elastic lower flap, augmented by pressure from the diver’s back, serves to hold stowed items in place.
Deploying a Surface Marker from the Storage Pak
A properly stowed marker will rest within the BC Storage Pak with the black nylon clip tail connected to the rear or hip D-ring. Should it be needed, the inflatable can be quickly deployed by simply locating the clip on the appropriate D-ring and making a quick tug. The accordion-folded marker slides out and is ready to be put to use.
Certain items, such as NiMH and SLA batteries, are covered by a 90-day conditional warranty that commences on the date of customer purchase. Following Halcyon’s recommended use and service guidelines provided in the manuals is essential in extending the practical lifetime of expendable items such as batteries and light bulbs.
Halcyon provides an owner’s manual with key products when they ship from the factory. Customers should become familiar with the manuals. Following the directions in these manuals will ensure a lengthy service life while maintaining peak performance.
The Halcyon warranty is a global warranty. As long as you have a valid sales receipt from an authorized Halcyon dealer, the warranty extends to all countries and shops, regardless of where the item was purchased. Any authorized Halcyon dealer can handle warranty returns to the factory with a valid receipt.
Unauthorized modifications/repairs, negligence, accidental damage, commercial use, or abuse are not covered by the warranty. Floods, leaks, punctures, and broken bulbs, etc., are not covered by the warranty unless they are the direct result of a material or workmanship defect.
HALCYON MANUFACTURING DISCLAIMS AND EXCLUDES ANY LIABILITY FOR INCIDENTAL OR CONSEQUENTIAL DAMAGES. SOME STATES IN THE U.S. AND CERTAIN FOREIGN COUNTRIES DO NOT ALLOW EXCLUSIONS OR LIMITATIONS OF LIABILITY FOR INCIDENTAL OR CONSEQUENTIAL DAMAGES, SO THIS MAY NOT APPLY TO YOU.
The following restrictions apply to this warranty:
When returning any gear to the factory, it is very important that you pay extra attention to packaging the shipment correctly. Damage caused by improper shipping will not be covered under warranty. We recommend packaging your equipment in a sturdy box, leaving room all around for packing materials such as bubble wrap, foam, or Styrofoam. Heavy metal parts, such as manifolds and batteries, can and will cause significant damage to themselves and to any other included gear if you don’t use proper packing materials.
Lights require extra attention when shipping. Always provide an extra layer of wrap around the lighthead. It is important that you return all parts of the lighting system (light, battery, and charger) for evaluation. If you are returning a light that has been flooded, do not secure the lid with the battery in the canister. Depending on the damage, the battery can off-gas hydrogen and create a risk of explosion.
Halcyon has spent years testing materials to make sure our wings are made to be as rugged as possible. We carefully select fabrics that balance long life and efficient design. Standard production Eclipse, Evolve and Explorer wings are constructed with an outer shell made from 1680-denier ballistic nylon and an internal bladder of 420-denier nylon. In comparison, most other manufacturers use only a 1,050-denier ballistic nylon in their outer shell and a urethane membrane inner bladder.
Ballistic nylon was originally developed for the US Department of Defense for use in flak jackets. Ballistic nylon is made of high-tenacity nylon in a basket-weave, giving an incredible tensile strength with increased abrasion resistance. Halcyon’s selection of materials is based on their abilities to stand up to the sort of conditions that one finds in extreme exploration making it an exceptional tool for all level of divers.
So what is “denier”? Denier is a unit of fineness for fibres, based on a standard mass per length of 1 gram per 9,000 meters of yarn. It is defined as the mass in grams per 9000 meters. Thus 9,000 meters of 15-denier nylon, used in nylon stockings, weighs 15 g/0.5 oz. A denser fibre (like the 1680-denier of our wings) results in a greater strength and abrasion resistance as compared to a lesser denier fabric.
Webbing
How do you recommend trimming the excess webbing on my BC System’s Secure Harness?
During assembly at the Halcyon factory we use an electric “hot knife” that cuts and melts the ends of the 2” webbing. In the field, an ordinary pair of scissors will be fine, followed by melting the cut ends with a butane lighter. You may notice that the fine frayed ends melt quickly (or possibly even catch fire) and form small blobs of hot nylon along the cut. We recommend working outside, over a flat worktable where you can place the hot end of the webbing on the table and smooth it flat with the side of the lighter.How much wear on the webbing is acceptable?
Over time and with use, the Secure Harness webbing will show signs of wear at the shoulder and waist strap area. After a few millimetres of wear, the webbing will stabilize and will continue to provide a rock-solid foundation for years of additional use. The use of 2” webbing straps is specifically intended to allow wear without compromising the integrity of the strap.
Wing Pull Dumps
Why is Halcyon now using a small fob on the end of the pull dump?
The OPV on the lower part of your Halcyon wing has a small string that allows a diver to release gas from the BC. This rear dump is ideal for removing gas while in a horizontal diving position. Some divers prefer to accentuate this string by installing a plastic fob on the end of the string. Yet, divers using a large fob (a large plastic ball is common) may find that it can catch on equipment (such as stages) and cause the wing to vent gas. In the past Halcyon accommodated this concern by removing the plastic ball from each of our BC valves. However, in response to requests from our customers and in order to accommodate certain international laws, Halcyon has installed a very small, streamlined pull-tab. Our testing indicates this tab will not interfere with a diver’s stage bottles; however, it remains easy to locate even for divers wearing thick gloves. This compromise allows Halcyon to accommodate legal requirements as well as customer requests. Divers that find this tab troublesome are welcome to remove it from their OPV.
How do I deploy a lift bag or surface marker using a spool?
Surface markers can be utilized in the event of an emergency; they may also be deployed as a means to maintain communication with a dive boat or surface personnel. The Halcyon series of inflatable devices includes a range of surface-signalling and life support devices.
Divers seeking a nearly fool-proof means to deploy a surface marker from depth may be interested in using a Halcyon spool. The Halcyon spool has no moving parts, reducing complexity and eliminating any risk of a jammed reel. In order to deploy the surface marker, one merely slips the looped end of the line through the eye of the Stainless Steel bolt snap at the bottom of the marker, passing the spool through the loop and securing it to the marker. A final charge of gas appropriate to the depth of release is added and the marker is released. The spool will turn freely as the marker rises to the surface. Should one lose control of the spool, the specially weighted Halcyon spool will sink slowly from the surface, providing the diver an opportunity to recover the line.
Cold-water Tip: Cold-water divers or those who prefer a handle will appreciate the easy operation of the Halcyon Cold-water Spool. This spool allows divers to create a convenient handle, improving efficiency and ease of operation.
What is the best way to stow a Halcyon lift device?
Many divers appreciate the unique Halcyon innovation that allowsthem to store a range of lift devices in the BC Storage Pocket affixed to their backplate. Stowing lift devices in this pocket provides streamlining, without compromising the ability for rapid deployment.Here are a few suggestions that will improve efficiency while working with the Halcyon Storage Pak.
Diver Alert Markers
The easiest of the markers to stow, various DAMs are simply folded accordion-style with the length of each fold just short of the full length of the BC Storage Pak.

Can an alert marker be stowed in a pocket?
The best means to stow a smaller alert marker is to simply roll it up and use the built-in shock cord loop for security. The No-Lock Connector is on a flexible tube that will allow it to be bent to the side slightly and rest under the shock cord loop while in a pocket. Use the Stainless Steel clip on the end of the tail to clip it to the pocket loop inside your Halcyon Bellows Pocket.The Halcyon Warranty Explained
