Aeris CompuMask HUD is a hoseless air-integrated dive computer. As name speaks for itself – computer was embedded into the scuba mask and it is located on the right side of it. With the help of Digital Optic System you can easily keep your eyes focused on diving and your hands free at the same time receive the important data, like current depth, elapsed dive time, cylinder pressure, and dive time remaining (DTR) and others, depending on the mode you have chosen.
Compumask can be recommended dive computer as for beginners and experienced recreational divers as well.

By means of sophisticated optical system Aeris CompuMask HUD displays all necessary data to the small screen located at the right bottom side of the mask. It provides you with clear and magnified digits, which you will see, regardless to the diving conditions and the information may be seen clearly by majority of people, regardless of vision.

This dive computer comes with just 2 buttons on the interactive control panel – Advance (top) button and Select (side) button. By using them you will program this dive computer for variety of settings and display information you need at certain time.
It has 1 Bar Graph shared between Tissue Loading display (No-Decompression and Decompression status) and Oxygen exposure display and these functions indicated by TL or O2 icons.
Aeris CompuMask HUD doesn't have special bar graph to visually represent our ascent speed, so it gives us only message 'SLO" and audio if our ascent rate is more than allowable at the certain depths.
Main display has few alternative screens to display many additional information during any operating mode and you will be able to access them by pressing Advance (top) button.
All parameters divided into 5 set groups (FO2 group, Alarms group, Time and Utilities, and Backlight). Below is a reference card with all functions that diver may set.

Aeris CompuMask HUD: Diving With Air & Nitrox

If we set our computer for Air, some data won't be displayed, like O2BG, PO2 and FO2, for example.
Now, it's about Dive Time Remaining (DTR) display. As Aeris CompuMask HUD constantly monitors your No-Deco (NDC) status, Oxygen (OTR) exposure and Air Time Remaining (ATR), it will display the least amount of time available at certain moment. It will be shown numarically with corresponding icons - NDC, OTR or ATR.
I, personally, like air-integrated dive computers because they have very important displays and alarms concerned with tank pressure and Air Time Remaining (ATR).
And Aeris CompuMask is not an exclusion from this rule!
Tank pressure alarm goes on when air pressure reaches the set point we adjust before diving.
When we have ATR only for 5 minutes - Aeris CompuMask HUD will warn us with audio. In this case we need to start our ascent and as we set 'End Pressure alarm' before diving - CompuMask calculates air consumption in such a way that we will have all necessary time for resurfacing (including Safety Stop and any Deco stops). When we resurface we will have air pressure as we set in 'End Pressure alarm' set point.
As I mentioned above Aeris CompuMask HUD doesn't have bar graph for ascent rate. So if you ascend faster than allowable maximum - you will get message 'SLO' and audio signal.
During initial adjustments, if you set Safety Stop to ON - you will get Safety Stop remainder upon reaching certain conditions with all related dive data and the most important for this case are Stop Depth and Timer values. If Safety Stop was set to OFF - nothing will happen, you may continue your ascent without any notification!
If we exceed our No-Decompression Limits (NDLs) - Aeris CompuMask HUD will activate Decompression mode. After this happened we must ascend to displayed depth or a bit below and decompress for the time displayed. Actually, you won't have any troubles of interpreting data - just follow the guidance of this dive computer and you will be safe! It is just a bit unusual seeing digits right next to your eyes!

If you are 'extremely lucky', you may get into violation modes, like Conditional and Delayed, for example.
Conditional Violation means that you ascended to shallower depth than required for Decompression Stop and maybe stayed at that shallower depth for a while.
If you descend within 3 meters below the Deco Stop depth displayed before 5 minutes elapsed - Aeris CompuMask HUD would still be in Decompression mode. But 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 off-gassing credit may be acquired.
Delayed Violations have their own kinds. For example, Delayed Violation # 1 happens when you stay longer than 5 minutes above the required Deco stop depth and Delayed Violation # 2 happens if you are at greater depth and Decompression procedure requires first Deco Stop depth between 18 and 21 meters.
That's just brief about violations.
For sure, Aeris CompuMask HUD monitors O2 exposure and PO2. If we get to the certain point when we have high values of these parameters - dive computer will alarm us about these conditions with all related dive data displayed.
Aeris CompuMask HUD: Diving In GAUGE Mode
Among Air, Nitrox and Freedive modes, Aeris CompuMask HUD can operate in Gauge mode. If set for this dive mode, computer will work as a depth gauge and timer without performing nitrogen and oxygen calculations.
Below you may see example of dive data displayed in Gauge dive mode from main and alternative screens:
Aeris CompuMask HUD: FREEdiving
Adjustable parameters for this kind of diving is different of what we set for Air and Nitrox. You may adjust following settings:
During freediving you will get main and alternative displays with example of information below:
To access Countdown Timer status display - press Advance (top) button.
In this mode Aeris CompuMask HUD calculates nitrogen loading accumulated from this and previous dives and it's based on the FO2 of Air. Even if you set dive computer for Nitrox set point before, it won't make any effect on calculations.
While freediving, you will get all alarms that you set before:
So, as you may see, Aeris CompuMask HUD is quite advanced dive computer and if you decide to get one - be ready to learn docs, there is a big manual and it should be learnt thoroughly! This dive instrument can not be taken just at one easy jump on it!
After the Transition period Aeris CompuMask HUD gives us access to the following modes with the help of Advance (top) button:
Plan mode allows us to see available depths and bottom times according to residual nitrogen and accumulated oxygen from previous dives and that data is also based on the FO2 set point and Personal Conservative Factor setting.
Logbook holds up to 24 the most recent dives and consists of 3 pages of dive data from Air, Nitrox and Gauge modes.
History stores data from dives with Air, Nitrox and data from Gauge mode and contains maximum number of dives, total dive hours and maximum depth achieved.
Aeris CompuMask HUD: What Divers Say
CompuMask HUD comes with lots of features and one of the main benefits of it – you may use this dive computer in different diving scenarios by setting it for air, nitrox, using it as a gauge or free diving.
It has many safety features, like 'Turn Pressure' and 'End Pressure' alarms that give you security, assurance, and extra-convenience while you are underwater.
Another clear benefit of using Aeris CompuMask HUD is - it frees your hands! It can be recommended dive computer if you are involved in activities of underwater photography, for instance!
To add from myself - manuals is not easy to figure out, but it is understandable because this is a high-tech dive instrument. Data cable connection can be a tricky one and from the first times - Aeris CompuMask HUD feels like bulky thing, but this feeling goes after few divings!
Let’s finish this page with words of one diver who looks like fell in love with his Aeris CompuMask HUD: “… I bought an Aeris CompuMask HUD some time ago, and I am hooked. I dove with it in a variety of environments, and it has spoiled me in the span of about 25 dives… it is awesome…”
