The Personal Float may be the Single Most-Important Piece of Underwater Equipment you ever Own. The Optional, Detachable 12" x 12" (30 5 x 30 5 cm) Dive Flags on both sides of the Float's Top makes it Highly-Visible from a Considerable-Distance. Also a 2" (5 cm) Wide Reflective Strip makes the Floats Highly-Visible at Night. The One-Way Oral Inflation Valve allows the Diver to Tightly-Inflate the Float at the Surface, while a One-Way Flapper Valve allows Air into the Bottom of the Float. The Over-Pressure/Dump Valve Vents Excess-Air as the Personal Float Ascends to the Surface and the Handle at the Top of the Float can be used as an Attachment-Point for a Light.
