Sea-Doo GTi

Sea-Doo is probably best known for its range of jetbikes, but it also produces a range of diver propulsion vehicles, and two in particular will catch the eye of recreational and technical divers. The Sea-Doo GTi (SRP: £349.99) is perfect for recreational divers who want to look like James Bond. It is depth-rated to 30m, the battery will last one-and-a-half hours, and it can carry a diver along at speeds up to 2mph.Technical divers will be more interested in the new Explorer (SRP: £549.99), which is depth-rated to 50m, can run at speeds up to 3.3mph, and the battery will last for up to 120 minutes.
