If you’ve ever tried to connect your GoPro or DJI action camera to your phone or tablet while it’s underwater, you’ve probably noticed something frustrating — the connection drops the moment the camera is submerged. Despite having built-in Wi-Fi and Bluetooth, most action cameras become unreachable as soon as they go below the surface.
Wi-Fi and Bluetooth rely on high-frequency radio waves, which are quickly absorbed by water. Even just a few centimetres beneath the surface, the signal can no longer travel — especially in saltwater.
This means that your mobile device can no longer:
Connect to your action camera’s app
Control recording or settings
View live footage in real time
Learn why wireless signals don’t travel through water — it all comes down to physics.
Both GoPro and DJI action cameras use Wi-Fi to connect to their companion apps — GoPro Quik and DJI Mimo — via 2.4GHz or 5GHz bands. These connections work well above water but fail once submerged.
Seavu solves the problem of underwater connectivity by physically relaying your action camera’s Wi-Fi and Bluetooth signal to the surface — where your phone or tablet can receive it just like normal.
The Seavu Seeker and Seavu Explorer kits use a three-part system:
Receiver (built into the Seeker Mount or Explorer Housing):
Captures your camera’s Wi-Fi and Bluetooth signal even when fully submerged.
Tether Cable:
A rugged, marine-grade cable transmits that signal from the receiver to the surface.
Transmitter (at the surface):
Rebroadcasts the signal wirelessly to your phone or tablet, allowing you to connect in real time via your camera’s app.
This allows for full remote control and live viewing — even while your camera is 7, 17, or 27 metres underwater.
Compact, lightweight, and designed for hands-on use, the Seeker can be attached to extension poles, burley pots, or boat rails. It’s the ultimate setup for recreational fishing, boat hull inspections, and training sessions at the pool.
Featuring a stabilised fin and modular design, the Explorer Kit is ideal for trolling, drifting, or anchoring. It’s perfect for those wanting steady, high-quality footage in moving water or from the seafloor.
