Cressi Signal Board Float. A mesh cover makes the bottom abrasion-proof and ensures effective drainage so that the buoy retains its lightweight at all times. The upper part is fitted with multipurpose pockets and a big expanding container. A mesh bag made of adjustable elastic straps will carry additional objects. A zipper along the center gives access to the two air tubes, which are kept separate for fail-safe buoyancy. A casing for the pole of the flag required by regulations is provided in the center of the front section of the float. Also red, the line is about 20 m long and is fitted with two plastic snap hooks. This buoy comes with a convenient whistle: an additional safety device.
