Deep Trekker Revolution NAV ROV
It's no good finding something interesting under the water if you don't have any way to get back to it. Deep Trecker's Revolution NAV ROV uses a floating transducer to let pilots see its position on Google Maps, leave a trail to show where they've been, and mark points of interest. The drone itself has a carbon fiber shell and body crafted from anodized aluminum and stainless steel, with a 260-degree revolving head that can rotate the sonar, 4K camera, and grabber arm as needed. It can reach depths of 1,000 feet thanks to six powerful thrusters — two vertical and four horizontal — and has quick-change batteries that last up to eight hours per charge.
