Rebreather divers and open circuit divers alike will appreciate our hybrid Surface Marker Tube. An oral/power inflator makes inflation simple for rebreather divers who do not have easy access to a regulator 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. Built-in carrying sleeve. ANSI safety orange. Made in the U.S.A.
