Product information comes from the research catalogue. Current specifications, price, availability and suitability should be confirmed with the maker.
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
It is spectacular hardware, but the open water, the training, the supervision and the maker’s operating limits are not optional footnotes.
