Aeris XR2 has 2 control buttons:

1. Advance button;
2. Select button

Using those buttons and their combos you will easily program, activate backlight, and retrieve information related to conditions you are.

This dive computer has 3 bar graphs that graphically show the nitrogen loading, oxygen toxicity and speed of your ascent:

1. Nitrogen Loading Bar Graph (NiBG) – this bar graph represents your nitrogen loading, and shows your No-Decompression and Decompression status. It’s divided to colour zones: grey zone – No-Decompression status, yellow – Caution (still No-Decompression), and red zone – Decompression;
2. O2 bar graph (O2BG) – this bar graph shows you the level of oxygen absorption from a single dive, or accumulated oxygen for the last 24 hours;
3. Variable Ascent Bar Graph (VARI) – this bar graph works as a speedometer and gives you graphical representation of how fast or slow you are ascending

During diving you will get up to 4 displays in No-Decompression mode and 3 displays in Decompression mode. To swap between them to see additional dive data you need to press ADVANCE button.

Dive computer has following modes of operation:

1. Surface mode, where you may set all the necessary parameters and access other post-dive functions;
2. Dive modes;
3. Post-Dive modes, where you may see Logbook and plan your next dives with Dive Planner, check your time to fly and time to desaturate status, download data to PC, and access Dive Simulator

From the Surface mode you may access Set mode that is devided into 2 Set modes.

Aeris XR2 has 3 dive modes:

1. Air;
2. Nitrox;
3. Gauge Mode – in this mode XR2 functions as a depth gauge and timer only and doesn’t perform calculations for nitrogen absorption and oxygen accumulation

Aeris XR2: Diving With Air & Nitrox

While diving in No-Decompression mode with dive computer set for Nitrox (if FO2 value was set for Air – you won’t have ALT#4 screen displayed), you will get following dive data displayed.

Aeris XR2 has automatic Safety Stop prompt warning, so during any No-Decompression dive you may get it. At that moment dive computer will beep on you and show you display with appropriate data, like Safety Stop Depth and Safety Stop Countdown timer the most important in this case. If you decide to miss it and resurface - there is no penalty, this Safety Stop is not Mandatory, like in Suunto models.

We may get Fast Ascent alarm as well, obviously, if we ascend too fast.

If we exceed No-Decompression Limits – dive computer will activate Decompression mode and guide us for proper decompression procedure. Upon the entry into Decompression mode dive computer will beep on you and red LED will flash to grab your attention. For Decompression it has few displays with related data and you need to press ADVANCE button to access them.

You may create violations during Decompression mode. It means that you ascended to shallower depth than required for Decompression Stop and maybe stayed at that shallower depth for a while.
In that case you won’t get any off-gassing credits but instead you will receive a penalty time that must be worked off before you will get any off-gassing credit.

Other violations may happen if Decompression Stop depth is required between 18 - 21 meters, or you descend below 99.5 meters. In these cases dive computer provides you with all appropriate dive data and guide you through these conditions.

As all other dive computers, Aeris XR2 constantly monitors PO2 value and our O2 level. So, if certain conditions exist - we will get irritating alarm going on and specific set of displays, corresponding to each scenario.

Aeris XR2: Diving In GAUGE Mode

Gauge is the other dive mode of XR2. In this mode maximum operational depth increased to 120 meters. Dive computer works as a depth gauge and timer only and doesn't calculate nitrogen and oxygen loading.

Typical data for this mode looks like following:

• current depth;
• max depth;
• VARI (while ascending);
• Elapsed Dive Time (EDT);
• time;
• temperature

After we got out of water and after Transition period in 10 minutes we will have access to following functions:

1. Pre Dive Planning Sequence (PDPS) – this function shows you bottom times for certain depths, according to your current nitrogen or oxygen accumulation from previous dives (if any);
2. Time to Fly Countdown Timer;
3. Desaturation Countdown Timer;
4. Log Mode – it stores data of your 24 most recent dives (battery removal does not make any affect on Log memory);
5. PC interface – this function allows you to download data from dive computer to PC by using special cable and software;
6. Reset function – this feature allows you to do RESET to all data including Logs, nitrogen and oxygen calculations, and FO2 set point – this is great beneficial feature if you use this dive computer for rental and training purposes;
7. Dive Simulator Mode – This is a perfect option to learn Aeris XR2; this function allows you to make a 'virtual' dive by entering data and observing the dive computer’s response, and how it displays certain information for different diving scenarios, like in real dive; another great thing about is that you may program this function to calculate all dive with current residual nitrogen and oxygen from previous dives

Aeris XR2: What Divers Say

When diving with Aeris XR2 we haven't noticed any troubles in operations, so couldn't say anything bad about it. Maybe only one thing is worth to mention - if you wear thick gloves - it may be not very convenient to press side button if you have console, because button sits deeper in the boot. That's all for our Cons!

Aeris XR2 Navcon	Dive-Computer-Wizard Rating

Aeris XR2 can be recommended dive computer for those divers, whether beginners or advanced, who wants to have flexibility and reliability of the multitasking instrument, but at the same time tough on their budget!
