Why Wi‑Fi Doesn’t Work Underwater
Water blocks radio signals, which is why Wi‑Fi and Bluetooth cut out as soon as you submerge an action camera. It’s not the camera’s fault — it’s a physics limitation. That’s 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 — Real‑Time Live View
Seavu solves this problem by creating a direct link between your underwater camera and your mobile device. Our kits use a built‑in receiver that captures the camera’s Wi‑Fi and Bluetooth, then transmits those signals through a marine‑proof Action Cable to the surface.

Tips for the Clearest Live View
- Use a stable mount or pole to keep the camera steady.
- Add lighting for deeper or murkier water.
- Keep an eye on your phone/tablet battery for longer sessions.
- Rinse your housing and kit in fresh water after use.
- Avoid hardwired ports/plugs that corrode in marine environments — Seavu’s sealed design prevents this.
Use Cases
- Fishing — see when fish are circling before they strike.
- Marine research — monitor reef life and habitats in real time.
- Inspections — check hulls, propellers, or underwater structures without diving.
