Worth the money

Best money I have spent. This fin has allowed me to paddle where I thought was not possible giving me the best joy, battery life is phenomenal.

One bonus that I did not consider when purchasing is I work with disabilities so now I get to teach people with disabilities how to paddle as this fin is the back up plan for if they become tired or unable to paddle. This product has opened so many doors and to be able to give these people the opportunity to take part in a sport that they thought was unobtainable is priceless I will be buying another one

Streamlined

Propeller pitch, blade surface, and feathering prop are all designed to reduce drag and resistance to a minimum.

Lightweight

At only 2.7 lb (nearly 1200g), you’ll hardly feel it.

Shockingly Resistant

Ready for rough seas, your Boost Fin's shock-resistant body is designed to take some hits.
