Becoming separated from the boat is a risk all of us run when diving in open ocean or any large body of water. This is why many divers insist on carrying an inflatable signaling device such as the five-foot tall Dive Rite AC2776 Diver Surface Marker. This is the big brother to our smaller "See Me" Safety tube. The Diver Surface Marker, however, is larger, has reflective tape at the top end, and is now sealed to help keep it inflated and upright. This improved model now features a power inflator and over pressure valve. "Quick-Draw" Sleeve: Improved "Quick-Draw" Sleeve features mesh for better drainage. All Dive Rite Lift and Marking devices (except the "See Me" Safety Tube) come with a "Quick-Draw" Sleeve (item number AC2753) for rapid deployment. By using a combination of snaps and quick links, you can easily attach this sleeve to the side or bottom of back plates or Transpac harnesses.
