What does the PrimeGuard extended warranty mean?
The BoostFin PrimeGuard extended warranty guarantees device replacement if a covered issue occurs during the warranty period.
How to control the Boost Fin?
The device is switched on and off by bringing the screwdriver handle with a magnet into the light indication area. The Hall sensor HS1 is responsible for turning on, and HS2 for turning off. A timer shutdown is also possible, the default value is 30 min, which can be configured via the app. The device also turns off automatically when the battery is completely discharged.
After successfully turning on the device, the motor is controlled by a radio remote control with two buttons. The remote can go on your wrist, shoulder, or paddle if you're on a SUP. Button A turns on the Short Boost mode, button B turns on the Long Boost mode. All parameters of these modes can be configured through the mobile app, which can be downloaded here. Pressing any of the buttons again turns off the motor.
What happens if I fall off the board?
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.
How much noise does Boost Fin make? Sharks?
The Boost Fin doesn't make any loud noise. We tested it out with surfers paddling 3ft away from the Boost Fin and they couldn't hear a thing. All they did was wondering how the heck was that surfer paddling so fast!
Later tests determined that sharks are attracted by frequencies ranging between approximately 10 and 800 Hz while we are using 30Mhz which equals 30000000 Hz. Plus you can also use a Shark Band bracelet for extra safety.
Waterproof Standards
Boost Fin meets the IPX8 waterproof standard (up to 10m / 32'9").
Each part and component exposed to saltwater are salt fog endurance resistant and certified for saltwater operation. All plugs, connectors, and other electrical contacted 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
