Abstract
An aquatic jet propulsion device basically includes a portable main control module, a first submersible propulsion unit and a first sub-two-way communication device. The portable main control module includes a main controller and a main two-way communication device. The first submersible propulsion unit includes a first motor, a first battery electrically connected to the first motor and a first motor controller operatively connected to the first motor to control a speed of the first motor. The first sub-two-way communication device is configured to communicate with the main two-way communication device. The main controller is programmed to output a first control signal to control the speed of the first motor of the first submersible propulsion unit via the first motor controller based on a first feedback signal containing first propulsion unit data that is received from the first sub-two-way communication device.
