I've been using my 735XT for 7 1/2 weeks now, 41 runs in all. After having had FR410(s) previously, I found it more complicated, and studied the manual for about a month before finally using it on my runs. Bit by bit, I became familiar with it, and got the Data Fields, etc, set the way I wanted.

My Polar device says my rate for the same run is about 130. I had the same problem years ago with an older Garmin device, except that one worked real well for a couple of years and then started intermittently registering off-the-wall-high rates. The GPS on that one went goofy too, so I bought the Polar. In a word, I don't trust the Garmin heart

You will be asked if you would like to FACTORY RESET your watch, select YES. Second Method: Relies on the 735xt already being setup in the app. On your smartphone, open Garmin Connect. Go to the OPTIONS menu and select SETTINGS (little three line icon top left I think) Select SYSTEM menu. Choose RESTORE DEFAULTS. Select YES to confirm. KzZv. 336 482 368 343 131 490 188 128 392
