Pool Distance Wildly Inaccurate Due to Flip Turns

McBreezy5k

Hi all, I recently got a Forerunner 965 and have been using it during pool swims in a 50-meter pool. The distance has been wildly inaccurate; it is always adding way too much distance on the swim. I was using an Apple Watch 3 prior to this and never had a problem.

I have narrowed it down to my flip turn. It seems to be fine when I'm swimming and constantly checking the distance, then when I flip turn, it will add 50 or 100 meters sometimes. Today I swam around 2500 meters and it registered 6500 meters.

I'm doing the exact same flip turn I was doing with Apple Watch 3 and never had an issue. And I have asked a swim coach if my flip turn technique is okay and they confirmed it was.

I've tried turning off Auto Rest and Stroke Detection, but it seemed to only make it worse. (I don't know what Self Evaluation does)

I've searched everywhere for a solution but can't find anything. I'm almost considering switching back to my Apple Watch 3 for the swim workouts which I really don't want to do because I love everything else about the Garmin.

Please help! Thank you!!

    For that big difference my guess is that it would come not from the turns (BTW in my experience if you do a "bad" turn it would decrease the number of pools, not increase it) but rather from stops or changes of swimming style in the middle of the pool. You can analyze this yourself: look at the laps in Garmin Connect. You'll see the times and understand what happened. An example would be something like this:

    1. 50m 1:01
    2. 50m 0:22
    3. 50m 0:41

    you can clearly see from the times that the 2nd and 35s "pool" is actually only one pool.
