Mares M2 is not an air-integrated dive computer, and it is suitable for recreational and for the beginners as well. It is packed with all necessary functions, reliable and easy to use Nitrox computer. If you decide to go for this one, you may make a console with pressure gauge, and optional compass unit kit.
It is pretty straightforward dive computer and if you think that 1 Nitrox gas mix is enough for you and do not wish to pay higher price for more sophisticated stuff - just make a console and you will have everything you need to diversify your diving adventures!

Here I agree with other divers, that M2 is missing Nitrogen Loading Bar Graph. Dive computer displays No-Decompression Time Remaining in minutes, but it would be very nice to have some indication of the nitrogen loading ratio on display.
Upon reaching certain conditions, M2 may give you Safety Stop prompt or 1 minute Deep stop prompt with all related dive information displayed.
As all other dive computers, Mares M2 constantly monitors your ascent rate, and if your ascent is faster than allowable at certain depth – dive computer beeps and shows you bar graph with all segments in solid colour and the last segment with word ‘Slow’.
When you set this dive computer for Nitrox, it monitors dive time and depth, and calculates safety limits for oxygen exposure according to FO2 that you set during initial adjustments.
Computer manages diving with Nitrox the same way it does when we dove with Air. The only difference is M2 calculates and displays few more crucial parameters, which are typical for Nitrox dives. Those parameters are:
So, while diving with Nitrox, you will see few more parameters and icons displayed in addition to what you have on displays when diving with Air. And here they are:
For Nitrox mode Mares M2 has two very important alarms:
If you reach a certain depth that is greater than allowable for Nitrox gas mix you set up before - M2 will give an alarm until you will ascend to shallower depth where PO2 will return to acceptable limits.
High O2 alarm pops up if your oxygen toxicity level reaches 75%. At this moment you need to think seriously about terminating the dive!
Decompression mode starts when we exceed No-Decompression Limits (NDLs). When No-decompression time remains approximately 1 minute, instrument produces an alarm to notify you. According to this alarm you should ascent, and if you do not – Mares M2 switches to Decompression mode and all calculations will run as for ‘deco' dive from that moment.

If we missed Decompression stop by any reason and didn't return to the Stop depth displayed within 3 minutes - dive computer would activate Omitted Stop mode and for the repetitive dive it would function as a depth gauge only without performing nitrogen and oxygen calculations.
Mares M2: Diving In GAUGE Mode
Next dive mode is Gauge. In this mode Mares M2 works as a depth gauge and timer only without performing calculations for nitrogen and oxygen exposure.
It has 2 layouts of display (you may switch between them by pressing the left button) and following information is displayed:
When we get out of water, we may access following functions:
