Scubapro Aladin H Matrix Dive Computer: Specifications and Who It Suits
The Scubapro Aladin H Matrix is a expert tier dive computer at $650 to $800, running a decompression model its maker does not publish in detail with a matrix lcd and optional air integration, accepting nitrox mixes up to 100 percent. Scubapro divers who want hoseless air integration and a mount they can move between rigs.
The Scubapro Aladin H Matrix is a expert tier dive computer in the $650 to $800 band. A hoseless computer with a quick release mount, sitting between the Aladin range and the G2. The matrix display reads as an instrument rather than a watch, which some divers strongly prefer.
The specifications below are the manufacturer's published figures. Where we could not confirm a figure against the maker's own documentation, the row is left out rather than guessed at, which is why some units on this site show fewer rows than others. On a page whose readers can check the work, a missing row is better than an invented one.

Who is the Aladin H Matrix for?
Scubapro divers who want hoseless air integration and a mount they can move between rigs.
An expert tier computer buys capability at the edges: trimix, closed circuit support, multiple transmitters, or a screen legible in conditions that defeat everything else. Very little of that is touched by a recreational profile. Buying one is defensible if you are heading toward technical training or you dive in conditions where legibility is the binding constraint, and hard to justify otherwise.
Who should not buy the Aladin H Matrix?
Divers who want a single wearable device for diving and daily use.
That is the more useful half of any specification page. Computers in this category are close enough on the things that matter, tracking depth and time and applying a model, that the deciding factor is usually a mismatch rather than a ranking: a screen you cannot read without glasses, a menu system nobody near you can teach, or a feature set aimed at diving you do not do. Compare against the alternatives at the bottom of this page before deciding.
What decompression model does it run, and why does that matter?
A decompression model is a mathematical description of how quickly inert gas moves into and out of body tissue, used to calculate how long you can stay at a depth before a direct ascent stops being acceptable. Every computer runs one, they disagree with each other, and the disagreement is real rather than cosmetic.
Whichever model a computer runs, the rule is unchanged: your own computer supersedes any published table, two computers on the same dive can legitimately disagree, and a buddy pair runs the dive on the more conservative of the two. The algorithm comparison covers the trade in detail, and the no-decompression limits table shows how far apart published figures can be.
What nitrox mixes can the Aladin H Matrix handle, and to what depth?
The Aladin H Matrix accepts oxygen fractions up to 100 percent. That covers every recreational mix and the oxygen-rich gases used for decompression in technical diving, so the computer will never be the limiting factor.
Maximum operating depth is set by the oxygen partial pressure, not by the computer. MOD in feet of sea water equals 33 multiplied by the maximum ppO2 divided by the oxygen fraction, minus one. The working maximum is 1.4 ata for the bottom phase of a dive, and 1.6 ata is a contingency ceiling used for decompression gas at rest rather than a target to plan against.
| Mix | MOD at 1.4 ata | MOD at 1.4 ata, metric | MOD at 1.6 ata |
|---|---|---|---|
| Air (21%) | 187 ft | 57 m | 218 ft |
| EAN28 | 132 ft | 40 m | 156 ft |
| EAN32 | 111 ft | 34 m | 132 ft |
| EAN36 | 95 ft | 29 m | 114 ft |
| EAN40 | 82 ft | 25 m | 99 ft |
| EAN50 | 59 ft | 18 m | 73 ft |
| EAN80 | 25 ft | 8 m | 33 ft |
| EAN100 | 13 ft | 4 m | 20 ft |
Run your own mix and your own planned depth through the nitrox MOD calculator, and pair it with the equivalent air depth calculator, which handles the nitrogen half of the same decision. MOD is an oxygen limit and EAD is a nitrogen calculation, and a nitrox dive is only planned when you have both.
Whatever the computer accepts, you analyse every fill yourself with an oxygen analyser , sign for it, and set the mix on the computer before you get in. A computer set to air on a nitrox fill is merely conservative. A computer set to EAN36 on an air fill is dangerous, because it will show you no-stop time you do not have.
Does the display suit the diving you do?
The Aladin H Matrix uses a matrix lcd. Display technology decides legibility more reliably than screen size does, and legibility is the specification that actually matters at depth.
Whatever the screen, check one thing in the shop before you buy: can you read it at arm's length without your glasses, in dim light, at a glance? Presbyopia arrives for most divers in their forties and it is the single most common reason a computer gets replaced.
How does air integration work on this unit?
Air integration is optional on the Aladin H Matrix and needs a matched transmitter, such as the Shearwater Swift for Shearwater units. Transmitters do not cross brands, so this is an ecosystem decision rather than an accessory purchase, and it typically adds several hundred dollars. Our advice is to buy the computer on its own merits, dive it a season, and add the transmitter only if you find yourself missing it.
Air integration does not change how much gas you have or how fast you use it. That is your own respiratory minute volume, and it is worth knowing as a number rather than as a feeling. The SAC rate calculator works it out from one logged dive, and the gas planning calculator turns it into a reserve and a turn pressure.
Gauge mode turns the computer into a depth and time instrument with no decompression calculation at all. It exists for divers running their own tables or their own plan, and it is not a way to dive past a no-stop limit without the computer complaining. Using it that way is technical diving without the training, and it is the single most common misuse of the mode.
How does it compare with the rest of the Scubapro range?
| Model | Tier | Display | Air integration | Price band |
|---|---|---|---|---|
| Aladin A1 | Beginner | Segment LCD with backlight | No | $280 to $360 |
| Luna 2.0 | Intermediate | Segment LCD | No | $350 to $450 |
| Aladin A2 | Intermediate | Segment LCD with backlight | Optional | $450 to $600 |
| G2 | Expert | Full colour LCD | Optional | $900 to $1,100 |
| G2 Tek | Expert | Full colour LCD | Optional | $1,000 to $1,200 |
Staying inside one brand has a genuine advantage that specification tables hide: the menu logic, the app and the transmitter all carry over, and a shop that services one unit usually knows the others. That matters most for air integration, where the transmitter is locked to the ecosystem.
What else should you look at in the same tier?
| Model | Brand | Algorithm | Price band |
|---|---|---|---|
| Eon Core | Suunto | Suunto Fused RGBM 2 | $650 to $800 |
| Descent G2 | Garmin | Bühlmann ZHL-16C with Gradient Factors | $700 to $850 |
| Nepto | Cressi | Cressi RGBM | $700 to $900 |
| Tern TX | Shearwater Research | Bühlmann ZHL-16C with Gradient Factors | $750 to $850 |
| Ocean | Suunto | $750 to $900 | |
| Genius | Mares | Mares-Wienke RGBM | $750 to $900 |
What should you check before you buy?
- Can you read it? At arm's length, in dim light, without glasses. This is the most common reason a computer is replaced, and no specification captures it.
- Can someone near you teach it? A unit your local shop rents and services is worth more than a slightly better one nobody around you has used.
- Does the battery arrangement suit your travel? Check the maker's current documentation, since battery arrangements change between revisions.
- Is the price band real for you? This is the middle of the market, which is where most divers who dive regularly should be shopping.
- Are you buying capability or permission? A computer that supports trimix does not qualify you to dive it. Training comes first, always.

Frequently asked questions
Does the Scubapro Aladin H Matrix support nitrox?
Yes. The Aladin H Matrix accepts oxygen fractions up to 100 percent. That covers every recreational nitrox mix and the oxygen-rich decompression gases used in technical diving, so the mix setting will never be the limiting factor on a recreational dive. Remember that the computer accepts a number you type in: you still analyse every fill yourself, verify the actual fraction with an analyser, and set the mix before you dive. On EAN32 at a 1.4 ata working limit the maximum operating depth is 111 feet.
What decompression model does the Scubapro Aladin H Matrix use?
The Aladin H Matrix runs a decompression model its maker does not publish in detail. Algorithms differ meaningfully between makers, and two computers on the same dive can show no-stop times that differ by many minutes. Where a maker does not publish the model by name, treat that as a reason to read the manual rather than as a reason to assume it is conservative. Whatever the model, your own computer supersedes any published table.
Does the Scubapro Aladin H Matrix have air integration?
Yes, optionally. The Aladin H Matrix supports a wireless tank pressure transmitter, sold separately. Transmitters do not cross brands, so buy the one matched to this unit and expect it to add several hundred dollars. Air integration is a convenience rather than a safety requirement, and a mechanical pressure gauge stays in the kit either way.
Is the Scubapro Aladin H Matrix a good choice for a new diver?
Probably not. At $650 to $800 this is an expert tier unit, and most of what you are paying for is capability a recreational profile never reaches. Divers who want a single wearable device for diving and daily use. A cheaper computer with a clear display teaches the same habits for a fraction of the money.
How we choose: we compare published manufacturer specifications, published training agency standards, and verified owner reviews across retailers. We do not test gear in person, and every depth rating, cylinder capacity and algorithm name quoted here is the manufacturer's published figure unless we say otherwise, so confirm it on the current spec sheet before you buy. Nothing here is dive instruction, and no calculator output on this site is a dive plan. Scuba diving carries a real risk of decompression sickness, oxygen toxicity, barotrauma and drowning. Dive within the limits of your certification, verify every plan with your own computer, and buy the training before the gear that assumes it.
