n addition to all the traditional functions of modern digital watches (time, date, stopwatch, countdown timer, alarm, second time zone), the SP1 has a "dive" function that is automatically activated when in contact with water and automatically switches off 30 seconds after leaving the water.
During the dive, all the essential information is displayed in real time (instantaneous depth, dive time and water temperature). Once on the surface, it automatically calculates the surface time (interval between the last and the next breath-hold).
The computer is also equipped with a memory that stores the last 200 snorkels. Easily accessible data stored for each dive is as follows: dive number, date and time of dive, maximum depth reached, dive duration and water temperature.
