Scubapro also distributed a French "wet submarine" version known as the Havas Mark 1 and Mark 3. The USN took delivery of at least one but never put it into service, then the SDV came along and changed everything.
A bit off topic but related:
The USMC also had a neato torpedo
to be confused with a Desert Patrol Vehicle) called Stidd DPD
(Diver Propulsion Device) which is more like a round sled made out of an old water heater. The driver sits inside, the passenger hangs on the back and it towed above. A few guys still monkey around with them.
