Sealife Float Strap
The universal SeaLife Float Strap (SL920) is designed to float many brands of underwater cameras, lights, and other waterproof devices. The Float Strap is especially important for the Micro HD, HD+, and Micro 2.0 cameras because of their negative buoyancy.
Can be worn on the wrist or with the quick clip attachment.
International orange color for high visibility.
The SL920 Float Strap has 3.5 ounces / 100 grams of positive lift force in fresh water and 3.6 ounces / 103 grams of lift in salt water. This lift force calculation is at the surface only. The float strap is made of closed-cell soft neoprene so it becomes less buoyant at depth because the neoprene air cells compress with water pressure.
It is not the camera weight that determines if the strap will float the camera or not. It is the weight of the camera in water that determines it’s buoyancy and required lift force. You can weigh your camera in water using a fish scale or pull force gauge. If you weigh it in fresh water, add 3% lift force for salt water.
