Dubbed the Sea Devil and 'Unterwasserschwimmhilfe' (underwater swimmers' float), Gabler's two-man SDV (Swimmer Delivery Vehicle) is a unique reintrepration of the Human Torpedo concept. It is closest to the Russian Sirena series of SDVs, although a closer comparison might be the Swedish (/British) Torpedo-SEAL DPV. Designed to fit within standard 533mm (21") submarine torpedo tubes, it collapses in on itself for storage. This reduces the length and diameter and allows two to be stored in a single torpedo tube.

The body is almost entirely diver accomodation so although it is torpedo shaped, it is quite slow and performance is generally similar to top-end DPVs.
