The fenix 2, Forerunner 910XT, and Garmin Swim uses arm movements and preconfigured data (such as pool size) to provide swim metrics.

Discrepancies in distance may be caused by multiple sources:

  • Inexperience in lap swimming
  • Switching stroke type mid-length
  • Stopping or walking mid-length
  • Dramatic changes of speeds mid-length
  • Performing drills that affect arm motion
  • Interruptions from pool traffic
  • Failing to setup pool size properly
  • Using a pool that is too small for your level of swimming proficiency

To decrease the amount of discrepancies:

  • If resting between lengths, use rest intervals
  • Use a strong push-off from the wall with a long streamlining (glide) phase
  • Swim continuously throughout the length at a consistent pace
  • Use one stroke type throughout each length
  • Continue to strive for a consistent stroke pattern
  • Use drill log 1 for drills that affect arm movement
  • If missing lengths as a strong swimmer, consider using a standard-sized pool 2

As swimming technique improves with the use of the above instructions, distance accuracy will improve.

1 - If drill log is not available; use rest intervals for drills that affect arm movement
2 - If lengths are being missed (under-counted) in a small pool, consider using a standard-sized pool as the watch may miss lengths for strong swimmers who only take a few strokes to cross small pools
