The diving depth of the DelfJet can be set on the control panel of
the water scooter according to individual needs. The standard diving
depth has been pre-programmed to 2.5 meters for fun seekers and amateur
divers. Higher spec models for scuba divers can dive to 50 meters.

of up to 120 meters. A two-man rescue model is also available.
Apply only light pressure and the Delfjet Waterscooter will obligingly
begin to dive. The electric drive mechanism incorporated into the
Delfjet was developed to produce the ideal amount of torque
with great efficiency and the 5 horsepower waterjet engine is emission-free
and almost totally silent.
The electronic jet engine is also service and maintenance free and
power comes from rechargeable high-energy Lithium-Ion cells that
provide enough energy to run the Delfjet for an hour at full speed.
