Abstract
An aquatic jet propulsion device basically includes a portable main control module, a plurality of submersible propulsion units and a sub-two-way communication device. The portable main control module includes a main controller and a main two-way communication device. Each of the submersible propulsion units includes a motor, a battery electrically connected to the motor and a motor controller operatively connected to the motor to control a speed of the motor. The sub-two-way communication device is configured to communicate with the main two-way communication device. The main controller is programmed to individually control the speed of the motors of the submersible propulsion units via the motor controllers.
