Lane length: The length of the lanes in your swimming pool. The watch will calculate your swimming data based on the lane length you set.
Therefore, every time you change a swimming pool, please set the lane length accordingly so that the watch can accurately record your swimming data.
Lap: under the pool swimming mode, swim for a distance equal to the lane length you set.
Stroke: finish a complete paddling action while wearing your watch on your wrist.
Stroke rate: the number of strokes per minute.
DPS: An abbreviation of distance per stroke, refers to the moving distance after finishing a complete stroke.
SWOLF: SWOLF is an important indicator for a swimmer, which uses scores to make a comprehensive assessment of your swimming speed. SWOLF for pool swimming mode = duration of one lap (in seconds) + number of strokes in a single lap. SWOLF for open water swimming mode will be calculated with a lap distance of 100 meters. The smaller the score number is, the higher the efficiency of your swimming.
The watch will recognize your swimming strokes under swimming mode and display the main swimming stroke you use.
The way our algorithm is designed is to track movement during sleep under typical sleep hours (22:00 p.m. – 8:00 a.m). If you are sleeping outside of a typical sleep hour range, the tracker will record as Short naps if the sleeping time is more than 20 mins.
Sleep detection is mainly based on “body movement” + “heart rate”. Body movement refers to physical activity, more specifically, the wrist activity of wearing band/watch (so there may be differences in the results of wearing sleep). When the body movement is small and the heart rate is low during sleep, it is considered as deep sleep. Conversely, when the body movement is vigorous and the heart rate is high, it is considered as light sleep.
nce your indoor running is ended and the recorded mileage is greater than 0.5km, you can select “Calibrate and Save” when saving the records. The calibrated mileage will optimize the algorithm to make subsequent mileage records more accurate.
If the mileage records are still inaccurate after multiple calibrations, you can select “Re-calibrate”.
