The Cressi Surface Marker Float is an easy to use and convenient surface marker buoy.
The surface marker buoy is self-sealing and is a so called tall SMB (uninflated dimensions: 176cm x 15cm), with huge lift, in a compact package. This makes it the ideal tool to attract attention on the surface, even if you're quite far away from land or the boat.
The SMB can be orally inflated as well as inflated with a second stage, and a special over-pressure valve prevents over-inflation. The over-pressure valve can also be used to release the air out of the Cressi Surface Marker Floats when required.
