1. 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 bar with a first end attached at a first attachment point along the inner side of a first one of said sleeves, said first attachment point comprising an attachment joint permitting the movement of said bar relative to said first one of said sleeves, the second end of said bar connectable to a second attachment point located on the inner side of the second of said sleeves, whereby connecting said second end of said bar to said second attachment point allows said bar to prevent said sleeves from coming within less than a predetermined minimum distance from each other during operation of the device.
