Though it is an amazing underwater scooter, it fails as a SUP propulsion unit. The connectors for wired controller are not waterproof, and corrode super easily. They get wet even if the modul is connected all the time. Unfortunately, in my opinion and experience, you are better off buying separated devices, one dedicated SUP propulsion and one underwater scooter. Especially given the price paid for this.
