Model ST

Because you'll wear the button on the wrist (which most of you would do), you can shut it off manually anytime. So don't worry, you won't have to chase your board.

The Zoomfins doesn't make any loud noise. We tested it out with surfers paddling 3ft away from the Zoomfin and they couldn't hear a thing. All they did was wonder how the heck was that surfer paddling so fast!

Each part and component exposed to saltwater are salt fog endurance resistant and certified for saltwater operation. All plugs, connectors, and other electrical contact surfaces are covered with rubber plugs to prevent them from water. Seawater can enter the charger port without any damage - there's a diode that essentially acts as a one-way switch for current. It allows current to flow easily in one direction, but severely restricts current from flowing in the opposite direction.

The main feature of the app is that you will be able to adjust your fin’s settings to comply with your needs and your style. You can play around with the setting to find just the right mode for yourself. Remember, more power equals more battery usage and vice versa. Remember, proper alignment and gentle handling are key to avoiding damage and ensuring a seamless attachment of your Zoomfins to the adapter.
