This popular recreational feature allows  the same 2 person SEAmagine submarine that normally performs deep dives with one pilot and one passenger inside the cabin to also be able to tour in shallow water 2 Passengers in the cabin by a trained external pilot in scuba.

______________________________________

This dual mode keeps the submersible size and weight much smaller than a 3 person vessel while still capable of performing deep dives from inside the cabin or perform shallow dives for 2 passengers from the external pilot station. 
_____________________________

The external pilot has full control of the vessel and of the equipment inside the cabin  so that the passengers can simply concentrate on the sight seeing.

Positively Buoyant At All Times
The submersible is at all times positively buoyant such that if the pilot was not on station with the submarine it  will always gently rise back to surface naturally on its own for topside to take over.

Pilot & Passenger Communication
The submersible's intercom system allows the external pilot and the passengers to talk freely. The pilot's full face mask with microphone and headset is hardwired to the submersible and allows all to talk to each other during the dive as well as communicate to topside via the wireless underwater communication system.

This optional external pilot feature has been well proven with thousands of dives performed in the tourism sector.
