Company TTRobotix, well known for manufacturing of drones carrying cameras, presented the second version of the mini-submarine Seawolf. It is a remote controlled, 7.7 kg heavy and 70 cm long submarine that can submerge up to 8 meters of depth. The most significant upgrade from the first version is the ability to carry GoPro cameras.

Seawolf has a top speed of 3.5 km/h and its 5000mAh strong battery can keep it underwater for around 50 minutes. The new Seawolf will be available from August this year with different versions for fresh and seawater. The difference lies predominantly in signals each model will use. The fresh water variant operates on FM frequencies, which cannot penetrate the more dense seawater. The seawater variant uses a different type of wireless communication and can also be controlled with cable hardware.

Complex toys never come cheap - prices will start at 999 USD (just under 900 EUR). Quite expensive, but nothing to be of any concern for James Cameron wannabes , desperate to make their first underwater documentary.
