In case you like to sip your cocktails while shooting underwater images or videos, or if circumstances do not allow one a safe dive, an underwater drone might be a possible solution.
The Titan underwater drone made by Geneinno is equipped with a 1/2.5-inch CMOS sensor to capture 8MP still photos and 4K video (with a fixed lens angle of 160°), and it can also stream a 1080p live view to the handheld controller. Two 1500-lumen lights help to bring light into the depths.
Its 9000mAh, 10.8-volt battery delivers a runtime of four hours per charge. The Titan can operate at depths up to 150m (492ft). Its maximum speed is 2m per second. Six controllable thrusters allow easy control of the drone. The Titan dimensions are 390 x 347 x 165mm and it weighs 4.4kg.
The unit can be remote-controlled via cable (with 50m, 100m and 150m cables available as extra accessories). Visual control works via a special app (IOS and Android), which allows the operator to see what the drone sees, controlling it accordingly by using a tablet or smartphone as a device for visual reference.
