With Forerunner 910XT, swimming will never be the same again. Designed for both open water and pool swimming, Forerunner 910XT is water resistant to 50 meters and is Garmin’s first multisport watch to offer extensive swim metrics, including swim distance, stroke identification, stroke count and pool lengths. It also computes a user’s swolf score – the sum of the time for one length plus the number of strokes for that length.
For example, 30 seconds plus 15 strokes equals a swolf score of 45. Swolf is a measurement of swimming efficiency and, like golf, lower is better. The 910XT’s robust design and easy operation make it suited for other water sports, including paddle boarding, kayaking and windsurfing to name a few.
