For the TrailblazerGirl who has everything…a two person submersible! Nuytco Research’s Dual DeepWorker is able to go to depths of 2,000 feet and can be operated tethered or untethered. This 6,500 pound, single atmosphere submersible is easy to maneuver with its six thrusters and oxygen systems allowing up to 80 man-hours at a time. The 24-inch diameter acrylic viewing domes are ideal for providing unobstructed views of the wonders of the sea!
