Dive computer Aeris A100 came with one control button, Dual Algorithm and two dive modes - looks like that's all we need to enjoy diving in full and not to dive too deep into the technical aspects! It can be recommended dive computer to other dive gear of the beginners in diving, and recreational divers with Nitrox certification who just want to go easy.
Aeris A100 is designed with CLEAR function. It can be a benefit for dive shops that give this Aeris dive computer for rent to students. But if you want to use this function yourself - do it with caution! Wait till you offgas completely, otherwise, you may be it trouble, if dive subsequently without full desaturation.

Below is a list of new features that we can set up in this new Aeris dive computer:
Aeris A100 is very easy to learn, set up and use. We can build a console on the base of this Aeris dive computer by adding submersible pressure gauge and compass. As it has Dual Algorithm, someone may want to use it as a backup device for other Aeris or Oceanic and Tusa brands. Beginners and recreational divers who require straightforward dive computer for an easy set up and diving will definitely find reliable buddy in Aeris A100.
As many other basic dive computers, Aeris A100 has 1 control button for setting up and retrieving information. While on Surface Mode, by pressing button (<2 sec), you may observe 3 surface displays with variety of info, or go to adjustments.
Dive computer has 2 coloured bar graphs - TLBG (diver's nitrogen loading), which is located at the left side of display and VARI (variable ascent rate), which is located on the right side of the screen.
TLBG bar graph has 20 segments - 13 No-DECO conditions, 6 caution conditions, and the last top segment of TLBG represents DECO mode.
The screen is large enough and easy to read. Aeris A100 designed with intuitive display layout with big and sharp digits, which are viewable at the any angle.
It's very easy to set up Aeris A100. Just 1 button does it all! As this is basic dive computer - there are not many parameters, as you may see for yourself. Someone may say that the menu is not very comfortable, as settings go one after another without possibility to step back. But that what we should expect from 1-button instrument. And there is nothing wrong with it!

Dive computer has Dual Algorithm (DSAT/Z+) - it means that you may choose between liberal and conservative diving. By using Dive Planner, we may plan the next dive and scroll through the depths at range 9 - 57 meters. Dive computer shows allowable No-Deco depths and bottom times depending on diver's nitrogen loading and oxygen saturation from previous dives, and also set Personal Conservative Factor.
Aeris A100: Diving With Air & Nitrox
Aeris A100 displays Dive Time Remaining (DTR) by monitoring your current depth, oxygen accumulation, NO-DECO status. It shows you not only your DTR as a NO-DECO (NDC) Time remaining at certain depth in minutes, but also displays status of TLBG by adding or taking away segments of that bar graph.
When you dive with compressed air – you have 79% of nitrogen and 21% of oxygen approximately. If this is the case – your tissues absorb nitrogen and Dive Time Remaining (DTR) is shown according to nitrogen loading.
When you dive with enriched air - Nitrox – it is a different scenario. You have different percentage of nitrogen and oxygen and your body responds differently to such a gas mix. In this case you are exposed to oxygen toxicity.

Dive computer has only two dive modes: Air and Nitrox with FO2 up to 50%. If you set Aeris A100 for Nitrox - dive computer will show NO-DECO ALT2 display with related to Nitrox data:
Aeris A100 doesn't have dedicated bar graph for O2% - only its digital representation.
If condition arises - you will be presented with automatic Safety Stop reminder. It set for 4.5 meters for 3 minutes.
If we ascend faster than allowable maximum limits - dive computer will activate Fast Ascent alarm. When this happens - all VARI segments will be flashing.
Dive computer constantly monitors our PO2 and O2 status and if certain conditions exists - it will give us with High O2 or High O2 alarms with all corresponding data on displays.
If we exceed our No-Decompression Limits (NDLs), Aeris A100 activates Decompression mode. Upon entry into this mode - full TLBG will flash and you will see guiding arrow and DECO Stop depth. From this moment all calculations will be made regarding to Decompression mode.
The most important data in this case:
Also dive computer shows other dive data on DECO Main and alternative displays:
During DECO mode diver may create violations, which happen if he/she ascends shallower and stays for some time above the displayed DECO stop depth without correcting it, or diver may descend deeper than Maximum Operational Depth (MOD), or decompression requires ceiling depth range between 18 m and 21 m deep – in this case Aeris A100 activates appropriate Violation mode and manages it to help us safely perform decompression and ascend in those situations.
After the dive and after the Transition period in 10 min, following functions and displays will be accessible:
Aeris A100 doesn't support PC download/upload function, so you should be aware of this!
Aeris A100: What Divers say
Aeris A100 is a very basic dive computer that is still not lacking some advanced features, like Dual Algorithm, for example. It can be recommended dive computer as a backup device, or for dive shops to give it for rent, or for recreational divers and beginners who don't require something fancy and technical!
During our test dives we found it very reliable and accurate. We could easily use it as a backup (after some adjustments) for Aeris Atom Ai and Oceanic Atom 2 dive computers - all calculations were pretty identical.
User manual is one of the most easiest to learn and follow, and dive computer itself is so intuitive, that we didn't even need to go through the manual sometime to understand what to do to set it or dive with it!
Display is easy to read, and its layout is very intuitive.
You may definitely invest in Aeris A100 dive computer if you require no more than basic instrument for pure recreational diving, for backup, or as an entry level device. It is accurate, reliable, user-friendly, and have all functions to cover variety of diving conditions that is only constrained of diving with Air and 1 Nitrox mix with FO2 up to 50%.
