NOTICE
The device is intended for surface swimming. Scuba
diving with the device may damage the product and will
void the warranty.
NOTE: The watch has wrist-based heart rate enabled
for swim activities. The watch is also compatible with
the HRM-Pro
™
, HRM-Swim
™
, and HRM-Tri
™
accessories. If
both wrist-based heart rate and chest heart rate data are
available, your watch uses the chest heart rate data.
Swim Terminology
Length: One trip down the pool.
Interval: One or more consecutive lengths. A new interval
starts after a rest.
Stroke: A stroke is counted every time your arm wearing
the watch completes a full cycle.
Swolf: Your swolf score is the sum of the time for one
pool length and the number of strokes for that length.
For example, 30 seconds plus 15 strokes equals a
swolf score of 45. For open water swimming, swolf
is calculated over 25 meters. Swolf is a measurement
of swimming efficiency and, like golf, a lower score is
better.
Critical swim speed (CSS): Your CSS is the theoretical
speed that you can maintain continuously without
exhaustion. You can use your CSS to guide your
training pace and monitor your improvement.
Stroke Types
Stroke type identification is available only for pool
swimming. Your stroke type is identified at the end of
a length. Stroke types appear in your swimming history
and in your Garmin Connect account. You can also select
stroke type as a custom data field (
).
Free
Freestyle

Tips for Swimming Activities
• Press LAP to record an interval during open water
swimming.
• Before starting a pool swimming activity, follow the on-
screen instructions to select your pool size or enter a
custom size.
The watch measures and records distance by
completed pool lengths. The pool size must be correct
to display accurate distance. The next time you start a
pool swimming activity, the watch uses this pool size.
You can hold MENU, select the activity settings, and
select Pool Size to change the size.
• For accurate results, swim the entire pool length, and
use one stroke type for the entire length. Pause the
activity timer when resting.
• Press LAP to record a rest during pool swimming (
).
The device automatically records swim intervals and
lengths for pool swimming.
