Cold water, long bottom
times, and/or
helium-based mixes
encourage divers to seek
an alternative means to
inflate their dry suit.
The use of a secondary
bottle filled with Argon
is the most common
method used to increase
the insulation
properties of thermal
garments. Halcyon offers
two time-tested methods,
providing quick, secure,
and lightweight mounting
options for drysuit
inflation sources. Our
compact OPV can be fit
to any conventional
first-stage regulator,
allowing excess
first-stage pressure to
vent from the system.
- 6-cf mounting kit secures a small inflation bottle directly to the Halcyon backplate.
- 14-cf mounting kit secures a larger inflation source to the diver’s single- or double-tank system.
- OctoGrip strap securely holds either size argon bottle to your single- or double-tank system.
- Compact Over Pressure Relief Valve fits to any conventional first stage.
