Adopting the static diving system is driven by a ballast tank with pump & motor unit. Start the pump to induct the water into the ballast tank. Control the amount of water in the ballast tank, the submarine can dive from the surface and stay underwater in static.
SEAWOLF is equipped with a auto-detect protecting system, if the system detects low battery power, low transmission signal, leakage, then the roll pump will auto start to flood the water out of the ballast tank to make the submarine float back to the surface.
Using the propulsion power unit and full elevator and rudder control, you can drive the submarine graceful sailing underwater. Install a GoPro HD action camera (not included) and you can take the photo or video of the amazing underwater scenes.
