Distance Recording
The Forerunner® device measures and records distance by completed pool lengths. The pool size must be correct to display accurate distance (Setting the Pool Size).
TIP:
For accurate results, swim the entire length, and use one stroke for the entire length. Pause the timer when resting.
TIP:
To help the device count your lengths, use a strong push off the wall and glide before your first stroke.
TIP:
When doing drills, you must either pause the timer or use the drill logging feature (Training with the Drill Log).
