Review Summary
SP2 is a wrist computer specifically conceived for free-diving and spear-fishing. The SP2, in addition to the typical functions of the best freediving computer, may be associated with a heart rate monitor. The Cardio Chest Strap (optional) can be used both in dive and chrono mode. It features 5.3 KHz allowing underwater data transmission. The heart rate can be used both in the water and during training out of the water. The connection to the PC, with the appropriate interface cable and the program dedicated DIVE MASTER (available at Omersub website) allows all dive data downloading. Software and SP2 Firmware are very easy to use and their updating is available at DIVE MASTER. SP2 features all functions of modern digital watches (time, date, chronograph, countdown timer, daily alarm, dual time) and a dive mode. The Dive mode activates automatically with the water contact and resumes automatically after around 30 seconds from the water exit. During the dive, the display will show in real time: Instant depth, dive time and water temperature. Once on the surface, the SP2 indicates automatically the surface time. SP2 records up to 250 dives. The data stored for each single dive is: sequence number of the dive, date and time, water temperature, duration of the dive and maximum depth.

There is no need to activate the Computer, it will automatically activate when submerged to 5' (1.5 meters) and will deactivate when depth is less than 5' (1.5 meters). Once you're diving, the SP2 will display current dive duration, depth, dive site, current time, maximum depth and water temperature. The depth resolution of the SP2 is 0.328' (0.1 meter) with a maximum depth of 330' (100 meters). All critical dive information is automatically placed in the Computer Dive Log Memory for later retrieval.
