After a recent trip with friends in which we all compared our Strava stats, it was a bit annoying to see how different the miles logged was so different between many of us. One of the guys mentioned that adding a speed sensor to the wheel makes the Garmin more accurate. Anyone know if that’s true?
I was looking at this one https://www.amazon.com/gp/product/B00JM6DKUA/ref=ox_sc_saved_title_1?smid=A3H9V1EMGQSHX7&psc=1 but the reviews are mixed. Anyone had good luck with that one or any other sensors to help improve accuracy?
