US Navy SEAL frogman wearing a LAR V Draeger rebreather

SBS divers do not usually need to go below 70ft, which they do to enter/leave submerged submarines, pilot Swimmer Delivery Vehicles (SDVs) or survey beaches. The specialised diving gear used by the SBS includes :
Rebreathers :
LAR V Draeger
a compact self-contained closed-circuit 're-breather' system designed for use in shallow waters. As with most military rebreathers, the Draeger recycles the exhaled oxygen which eliminates the bubble produced by traditional SCUBA gear, making the wearer much harder to detect.
Divex Shadow
It has been reported that the SBS are now using Divex Shadow series of rebreathers. The Shadow oxygen rebreather has a duration of up to 6 hours. The Shadow is compatible with the Divex Digicom 3000m Diver Through Water Communications system and Divex Stealth Full Face Dual Mode Mask. A more advanced model, which can be used at lower depths, the Shadow Excursion, uses an oxygen/nitrox mix. The Full Face mask that comes with the Shadow can quickly interface with on-board air supplies found on SDVs.
