Make your ascents safe and easy. 

Rebreather divers and open circuit divers alike will appreciate our hybrid Surface Marker Tube. An oral/power inflator makes our SMT ideal for rebreather divers who do not have a regulator easily available for inflation. Likewise, a funnel-shaped, anti-spill baffle allows open circuit divers to inflate this SMT with a regulator. A standard over pressurization valve allows excess gas to vent during ascent and/or to depressurize the bag at the surface. Includes a built-in carrying sleeve.
