A useful reality check
The jetpack is used in open water by breath-hold divers. Training, supervision and the maker’s operating limits matter more than the novelty of the hardware.
Why it caught our eye
CudaJet mounts twin water-thrust units behind a breath-hold diver and puts the control in the diver’s hands. It is spectacular hardware, but the water, training and operating limits are not optional footnotes.
