The value priced Dive Alert™ Orange SMB is inflated with your second stage regulator. It has a one-way duckbill baffle closed base, which prevents air from releasing at the surface. You may inflate the SMB on the surface OR at depth because an over-pressure valve (OPV) prevents over-inflation but also allows for rapid deflation when required. The nylon strap at the top provides an attachment point for a light or slate and two strips of reflective tape across the top significantly increases visibility.

The SMB is {65 in | 165 cm} long by {8 in | 20.3 cm} wide and although it should not be used as a lift bag it has approximately {40 lbs | 18.1 kgs} of buoyancy. Constructed of durable 400 denier polyurethane coated nylon material in high visibility orange color on both sides and includes two velcro straps to retain a tidy compact roll for storage.
