During times when divers descended with only one two-hose regulator and buoyancy compensator did not exist, divers’ biggest worry was to have an emergency, obliging them to ascent as fast as possible. Safe-T-Float was produced in Canada for this purpose by International Divers in 1957. It was a small sausage-like device in a belt to be fastened at the waist, functioning with a CO2 bottle: it was sufficient to press its lever and, in few seconds, a bag at the chest level expanded which dragged the diver on the surface, at all speed. The more pessimistic ones could choose the double version, with two bags, paired and independent.
