Anyone here done any comparisons on the accuracy of the Apple Watch VS. "better" GPS speed watches? I tend to ignore single top speeds and look more closely at 2 sec or 100M readings. I'm getting reasonably consistent speed results but am unsure how much stock to put into the actual numbers. Cheers!

Apple Watch Ultra user here - very happy. Like Relapse said, it has a much more advanced GPS system than the previous models.

I have not compared to Garmin (I have an older Fenix) though or any other standalone devices. From my perspective, it does everything that I want from a smart watch and I am happy to forego potential accuracy with standalone devices in exchange for all the features and benefits that the Ultra brings to the table.

I also look over time and the Ultra is consistent from session to session and over periods of weeks to months. So even if the absolute reading is marginally incorrect, it is consistenly incorrect and that is also important. I hope that makes sense.

I also wondered, so decided to turn Waterspeed on (Apple watch series 7) while driving. It matched my car speeds very accurately. I then used it on the bike, and did some very hard braking stops, and it was very good. Occasionally it would show a slower than actual speed through tight turns on a mountain bike course, but was within 3km/hr compared to the bike computer.

My SE does a good job, especially during unscheduled rapid de-boarding events.

Any tips please?
When I use dawn patrol with the Apple Ultra, even when I have it set to "fast waves" it records waves that I just paddle for and dont even catch. Also it records really high "fastest speeds" I think if I fall and my arm moves quickly it records that as fastest speed? So wave count and fastest speed is totally wrong. Did not have the problem with the same settings on the previous gen apple watch and dont know how to fix it. Anyone have same issues and come up with a fix? Tks

Medium is what Piros uses. I just use Strava
