Garmin Swim Calibration
The Garmin Swim does not require calibration for swimming. The only requirement is to input the size of the pool. Keying in the pool size is found in Swimming from the menu on the Garmin Swim.
When entering a different pool, the pool size can be adjusted in Swimming under Menu. The pool length can be set to 25 meters, 25 yards, 50 meters, or customized. Customizing the pool size can be set within a range of 20 to 100 meters or 22 to 100 yards.
A consistent swimming form, pressing pause for any rest periods, and using a strong push-off the wall will aid the Garmin Swim in accurately measuring distance.
