Claims4
An underwater propulsion device comprising:
- (a) a pair of rigid sleeves, each for fitting around one of a user's lower legs below the knees, and each of said sleeves extending down to just above said user's ankles;
- (b) a battery-powered underwater propulsion unit attached to each of said sleeves;
- (c) a battery sealed in a watertight compartment, said battery worn by said user, and said battery connected to at least one of said propulsion units;
- and
- (d) a throttle control system comprising a foot pedal mount attached to at least one of said sleeves, wherein said foot pedal mount is capable of a swivel motion about an axis running through the center of the length of said one of said sleeves in response to a swivel motion of said user's foot about said axis, said motion controlling the throttle of at least one of said propulsion units.
