SP1 is a wrist computer specifically conceived for free-diving and spear-fishing. SP1 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 SP1 indicates automatically the surface time. SP1 records up to 200 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.
Current Time Mode Display:
The SP1 will display time in hour, minutes and seconds. The time can be displayed in a 12 or 24 hour format. In the Current Time Mode the user can also navigate to display the month, date, day of the week, hourly chime, daily alarm and temperature display. The Computer has an auto calendar from years 2000 to 2099
The Chronographer Mode has a resolution of 1/100 of a second with a range of 99 hours, 59 minutes and 59.99 seconds. The Chronograph Mode can also display a split time function.
Countdown Timer Mode:
In the Countdown Timer Mode the SP1 has a resolution of 1 second with a range of 99 hours 59 minutes and 59 seconds. The Computer will beep once per minute for the last 10 minutes, beep once per 10 second for the last minute and beep once per second for the last 5 seconds. The SP1 will also beep for 30 seconds when countdown is to zero.
Dive Mode: The SP1 Computer has a diver selectable feature for sea or lake (fresh) water environments and to display depth information in feet or meters. 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 SP1 will display current dive duration, depth, dive site, current time, maximum depth and water temperature. The depth resolution of the SP1 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.
The SP1 can be set to read temperature in Fahrenheit or Celsius with a resolution of 1 F / 1 C and a range from 14 F to 140 F (-10 C to +60 C).
Dive Recall Mode:
The SP1 Computer has a maximum record storage capacity of 199 and each dive recorded contains record number, starting time and date, dive duration, maximum dive depth minimum water temperature, dive site indication, and a delete current/previous/all records function.
The SP1 Computer has 4 Mode Buttons for navigating through all functions. The EL" Button will activate the Computers Backlight for viewing information in low light conditions. The SP1 is powered by a 3 volt CR2032 battery and comes with a comprehensive Owner's Manual.
This product has a limited warranty of 12 months.

Comments about Omer Sporasub SP1 Wrist Computer:
I wanted a watch to use as backup in case dive computer went out...just something to show depth & time. I am so impressed with this watch & have had many many compliments. I use it more than my dive computer during dives when just wanting to check time & depth. My favorite & most used aspect of the watch is the more accurate temperature reading. My dive computer takes much, much longer to read the temperature & this dive watch takes seconds as the sensor is on the outside. Also when my dive computer is sitting on the surface if it is in sun it heats up & so during the dive it takes it even longer to actually record the real water temperature. Having this watch is great for accurate temperature readings. I dive mostly in lakes where the surface will be in 80s during summer & at typical depths I dive will drop down to 50-60s so having this watch be able to show this extreme temperature change rather quickly is awesome. My dive computer will actually still try to read the cold depths when I am ascending back into warm water. (It also displays the outside temperature when I am on the surface). I also really like the fact I can turn the screen off to save battery. It saves 200 dives which is also a great aspect of it. The watch itself is not bulky & heavy so I don't really even notice it when it is on. The strap is a thick rubber type so seems that it will hold up well. It adjusts to many sizes so I am able to wear it with no wetsuit as well as when I pile on my 3mm & 5mm suit & gloves. The watch immediately goes into dive mode & then also goes into immediate surface interval mode which is also handy so I don't have to access my dive computer to check SI time. I also really like how the time shows seconds. My dive computer rounds up so nice to see EXACTLY how much time has gone by. The depth reading is also much more accurate. Instead of reading 28' on dive computer my watch may show 27.4'. I am a female, but I like a bigger watch face...not quite the large faces of a man's watch & not the small faces of a woman's watch. This watch face size is just right! Many functions, easy to use, like the backlight (works very very well & defaults to stay on long enough to get readings). All in all I am extremely happy with my purchase & would recommend to ANY divers as a good back up source for depth & time! Love love love!!!
