First Impression
In a hurry and looking for the gist of things? Here is our review in short. Keep reading for the entire version.
The Aqualung i100 is the ultra-budget entry dive computer made by Aqualung and is stripped down to the absolute minimum. Like the budget offerings from Mares and Cressi, it features a one-button design that just works out of the box and gives you all that's necessary to dive right in.
I also like that the Aqualung i100 features a freediving mode, and different gas blends, and just looks super nicer with its black or black and blue finish.
Despite its shortcomings, I like the Aqualung i100 way more than other contenders for several reasons.
First off, it just looks super nicer with its black or black-and-blue finish.
Secondly, it features one additional mode to the others which is Free Dive. This way, you can use your dive computer for freediving without having to buy a new model.
Last but not least, the Aqualung i100 allows you to switch gases (up to 2) underwater very easily for some entry-level decompression procedures.
Honestly, I would NOT recommend this dive computer to anyone wanting to get into the technical diving area anytime soon, but it is possible.
The Aqualung logbook app is really cool, too, and works like a charm between all your devices. This compensates for the only 24 dives which are stored in the device itself.
What I really like about any of the Aqualung computers is that they all use the Bühmann-Z16 algorithm instead of the RGBM.
This means you will be able to calculate your dives by hand or using the dive planner mode on your computer and know exactly what is going to happen at which depth.

Conclusion
The Aqualung i100 is clearly a dive computer for beginners that has a lot of features for an introductory offering.
Aqualung gets a lot of things right with this dive computer, however, it isn’t anything spectacular.
If you are on a budget, you get a lot of bang for your buck, including Nitrox mode, gas switches, and automatic altitude detection.
That’s cool, especially when you are going altitude diving!
A big drawback is the dull and small display. There is no backlight and that makes it hard to read both underwater and at the surface. Moreover, the interface cable is outrageously expensive considering it’s a low low-budget dive computer.
I cannot but feel that in the end, for just a little bit more you can get the Aqualung i200 as a full-featured 4-button dive computer.
Alternatives
In the super low-budget dive computer market, there are multiple options to check out.
The Mares Puck Pro is a popular choice for beginners that’s very easy to use, and has a comparable feature set but a so much better display! If you want to spend a bit more but get A LOT of extra value, the Suunto Zoop Novo is our go-to choice!
