Why WiโFi Doesnโt Work Underwater
Water blocks radio signals, which is why WiโFi and Bluetooth cut out as soon as you submerge an action camera. Itโs not the cameraโs fault โ itโs a physics limitation. Thatโs why people are often frustrated when their GoPro or DJI connects on the boat but instantly loses signal once dropped into the water.

The Seavu Solution โ RealโTime Live View
Seavu solves this problem by creating a direct link between your underwater camera and your mobile device. Our kits use a builtโin receiver that captures the cameraโs WiโFi and Bluetooth, then transmits those signals through a marineโproof Action Cable to the surface.
