Flag An interesting new Diver propulsion Device, this time from Israel. Technical Equipment International (TEI) Ltd ae better known for their military night vision and related underwater equipment.

The Sea Chariot is a single diver device where you lay prone behind a small water shield. Unusually there is onboard air supply (a feature normally reserved for larger craft) and it uses three electric thrusters, with two in the forward hydroplanes. The configuration likely results in very high agility.
