Inflator Positioning for Sidemount Diving


The JT is totally different from the other Nomads. We addressed some requests from cave divers. The over pressure valve with pull string dump (OPV) is not on the neck, but on the under side so it’s protected from the ceiling of caves. It can’t be ripped off going thru a restriction and locating it on the underside helps keep water out. It won’t stop it, if you pull on it and air doesn’t come out immediately then water is going in, it’s  just physics. We also put an OPV on both sides of the bottom of the bladder to take advantage of the 360 flow thru on the bottom. Talking to some explorer buddies they got themselves into some situations where the ability to dump from either side was a good thing because of  stage bottles or an awkward restriction.

The corrugated hose and inflator is positioned above the waist belt so it doesn’t interfere with the waist belt and d rings.

The problem with switching the OPV and inflator on a standard wing or Nomad is the inflator assembly has to come up from below the waist belt so there is some congestion at the belt area and by removing the OPV from the bottom of the bladder has created some stressful situations for divers in a head first vertical restriction. By locating the OPV on the bottom and top we can move the inflator assembly to a more convenient location on the under side of the wing.

The Nomad JT was designed for the cave diver and the features are designed for the overhead, sidemount environment. It doesn’t have the flexibility of diving alternate tank configurations, but it sure is fun to dive. VIDEO: Nomad JT Inflator Placement
