The RSV-1 is a modular control valve that allows a diver to switch breathing gas supplies in less than a second.

The RSV-1 is particularly useful to a Public Safety Diver utilizing a full-face mask. 

The RSV-1  allows the diver to switch to their alternate air supply without removing their mask (a valuable feature when diving in toxic or hazardous locations).

The RSV-1 allows divers the ability to assist a entangled diver by being able to pass off a spare tank or connect a surface gas supply to the RSV-1. 

With the white button down and the safety clip installed, the RSV-1 is routing the breathing gas through the threaded fitting which is the Primary gas supply.

Release the safety clip and press the button on the bottom of the RSV-1 and the RSV-1 is routing the breathing gas through the quick disconnect fitting and you are on your alternate supply

(which is indicated by the brightly colored band at the top of the RSV-1 shuttle.

With only one moving part, maintenance is easy. Simply freshwater rinse the RSV-1 along with your other dive gear.  

Dry the RSV-1 and remove only one screw in order to disassemble and grease the "O"-rings.

The RSV-1 is made from Delrin (a high tech engineering plastic from DuPont).

The fittings are made from stainless and all "O"-rings are Viton.

The three connection ports are identical, which allows the RSV-1 to be configured to suit the dive mission. 

RSV-1 adapters and configurations currently available for: Interspiro AGA mask, OTS Guardian, EXOxmask, and most standard regulators with a 9/16-18 thread.

Quick disconnect fittings include: AGA, Seaquest Air Source, and Scuba ProAir 2 fittings.

Harness mount and customized fittings are available. The RSV-1 is intended for use by Public Safety, Military, Technical and Commercial Divers.

The SBV-1 allows a diver to easily breathe air directly into the Oral/Nasal Cavity of a full-face mask without the risk of CO2 buildup, mask fogging or needing to force exhalation to overcome the resriction of second stage exhaust valve.

The SBV-1 design allows divers to stand fully operational on the surface without reducing their gas supply.

The SBV-1 is available for most full-face masks. The low profile of the SBV-1 reduces the chance of an entanglement. 


The SBV-1 is designed for divers utilizing a full-face mask. It is perfect for public safety divers that dress en route to a call.

A diver can arrive fully dressed, mask on, ready to enter the water.

Backup and 90% divers can maintain a ready position with the mask on, instead of placing the mask on only in the event of an emergency.

This reduces the possibility of a backup diver rushing, placing the mask on improperly and not maintaining a seal, wasting precious time during potential life-or-death situation.

For instructors, the SBV-1 saves time and energy by allowing them to talk through the SBV-1 and not having to remove their mask. 

There is only one moving part. Simply freshwater rinse the SBV-1 along with the full-face mask. Periodically grease the "O" rings, and you're done!

To place the SBV-1 on an AGA full-face mask, simply remove the communications port cover by removing the two screws that attach the cover.

Replace the cover with the SBV-1 and tighten the two screws.

To place the SBV-1 on a OTS Guardian Mask, remove the communications port cover and press in the SBV-1 with its adapter plate.

The SBV is available for AGA, OTS Guardian, Ocean Reef and EXO full-face masks.

The SBV-1 can be fitted with your communications microphone and because the SBV-1 center section is the same for all masks.

The SBV-1 with the communications connection can be used on different masks without the need to buy a dedicated comm system for every mask.
