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.

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.
