Mares Nemo Excel is one of the most sophisticated dive computers, made as a dive watch computer that was widely used in scubadiving community not long time ago. It suitable for beginners, advanced, and technical divers, thanks to wide variety of features.
Nemo Excel is not an air-integrated dive computer, so you wouldn’t find in it features, which are integral functions of air-integrated dive computers, like Tank pressure, Air Time Remaining (ATR), your Breathing ratio calculation etc.
This dive computer comes with 2 years warranty and has optional PC optical interface unit named Iris. You may buy this accessory for around USD100, and actually you should if you want to have more extensive storage of your diving activities placed in your PC.

Instrument is designed with Safety Stop automatic prompt, and if max depth of the dive gets more than 10 meters - dive computer activates Safety Stop prompt upon you ascent with all vital information displayed for this situation.
To monitor your ascent, dive computer has special algorithm, and if you ascent too fast – it warns you by triggering an alarm with displayed message SLOW and Ascent Rate bar graph. This alarm keeps buzzing on you until you slow ascent below the maximum allowable limit.
Nemo Excel has Deep Stop function and upon reaching certain conditions of dive it will give us audio alarm with Deep Stop message on the display bar and Deep Stop depth and time. There may be more than one deep stop and it depends on dive profile.
If we exceed our No-Decompression Limits (NDLs) – dive computer will activate Decompression mode. All data that we will get after that is related to this mode.

Nemo Excel monitors Oxygen Partial Pressure and if you exceed the limit, you programmed before, Excel will trigger an alarm, and this alarm will continue until you ascend enough to bring the PO2 back to the value you set in the program.
Along with feature mentioned right above, this dive computer monitors the level of Oxygen toxicity of your Central Nervous System (CNS). When this value will exceed 75% - alarm will be triggered. During a dive you will see %CNS value shown on the display.
Mares Nemo Excel: Diving In GAUGE Mode
Next dive mode of this computer is Gauge mode. In Gauge (Bottom Timer) mode Nemo Excel works as a depth gauge and timer and doesn’t perform computations for No-Decompression Limits and for Decompression stop times.
Typical layout of the display looks like example below:

Another dive mode is FREEdive. This mode has few specific parameters and their corresponding alarms. Below is a list of them:
During freedive Mares Nemo Excel shows following dive data:
In post-diving stage Nemo Excel has following functions that we are interested in:
I think, one and only one main disadvantage of such a nice dive computer is that there is NO ‘diver replaceable battery’ option, but still some of our advanced guys may replace it themselves! And in that case Mares declines all warranty if something happens after you replaced battery incorrectly - this is an issue with all dive computer manufacturers.
If battery is replaced at the special service center, computer keeps the Log Book data, but, obviously, it clears residual nitrogen memory and stops RGBM computations for any previous dives you have done.
