How precise is the lap timer?

Millisecond precision — within the limits of human reaction time on the lap button — perfect for track, swim, cycling and rowing splits.

Can I see all my lap splits?

Yes. Each tap records a split and the full list is visible without losing the running cumulative time.

Will it work poolside or trackside?

Yes. Wake-lock keeps the screen lit and the big digits are visible from several meters away.

Does it support marathon distances?

Yes — the timer runs cleanly for hours. /stopwatch/lap/marathon and /stopwatch/lap/ultra-100k are battery-friendly.
