User Experience


Mere looking at the aqualung computer looks great, especially in its blue color form, and also the blue ring on top is made in the same shape as the legend regulators from Aqua Lung. The aqualung computer doesn’t feel too heavy, and when you take a look at the dimensions, they are roughly the same as its competitors.

Users of AquaLang i300 classify the watch as one of the best freediving watches.

Many users conclude that the strap which is long enough to fit over all suits, even thick dry suits will remain the best part of the aqualung i100 watch.

Diving and everyday use

According to a Dive professional who had the opportunity to get his hands on the new AquaLang i100, he classified it as a perfect dive computer for the new diver. With simple one-button navigation, users can select four operating modes and manage two gases. User-changeable 3.0V CR2450 lithium battery, the Aqua computer always retains all user’s settings and calculations between battery changes.

Users also talk about some safety features it has such as audible alarms and high-visibility LED warning lights.


Users are happy with the essential functionality that it provides, they include a compact design and a great price.  4 operating modes. Air, Nitrox, Gauge, and Free Dive (tracks calculations to allow switching between Dive and Free).  User changeable battery and data retention. Maintains settings and calculations between battery changes. 2 Nitrox gases up to 100% changeable underwater

Navigation: Aqua Lung i300 computer opted for a one-button design to simplify underwater navigation. Straight out of the box you get the surface time and which mode you’re in. If you press once, you should get the last dive you’ve made but many users have complained it only shows dives made in the last 24 hours because their latest dive always doesn’t show up.  Other screens are the time and date and the no-fly time and time to full de-saturation.

Great Scuba and Free Modes: Many users have praised the AquaLung i300 for these great features ha. Apart from the normal air mode, you can also dive with Enriched Air Nitrox up to 100 percent up to 2 different gasses.

It has a gauge mode but this freedive mode is something entirely different. Normally if you go freediving with your dive computer you’re banned from diving for 24 hours. The AquaLung i100 keeps calculating while freediving which prevents a 24-hour ban from scuba diving and frees you up to switch between free and scuba mode all you want. So many users classify this as a really cool feature that they haven’t come across a lot.


  • Cheapest computer on the market with an option for gas switch
  • You can switch between freediving and scuba diving on the same day
  • Self-replaceable battery
  • 2 Colors
  • One button navigation


  • No compass included
  • Diverlog needs to be bought since it is not included

Divers have the option of choosing between three modes of functionality which consist of Dive, Gauge, and Free Mode. Though the i100 is easy to operate and use, you should get the most out of it if you are a new user if you take some time to familiarize yourself with its display and modes of operation.

Please note that the i100 does not have an off button or command. If no buttons are pressed or dive made within 2 hours, the unit will shut itself off. However, the i100 does stay on for up to twenty-four hours after a dive, counting down FLY (time to fly) and SAT (destruction time)if a dive has been made.
