The surf activity feature on Garmin devices is completely useless.
I have used both an Instinct Solar Surf watch and a Fénix 7s for surfing, and the results have consistently been disappointing.
For instance, during my most recent surf session, my Instinct Solar Surf reported a wave with a maximum speed of 186.5 kph, which is bizarre.
It's baffling how inaccurate this can be. You offer some of the best devices on the market, yet if you're selling a surf watch, the software aspect requires significant improvement.
