The AquaLung i100 Dive Computer is a simple and easy to use entry level dive computer for the new diver. With a single button navigation system, you can select from four operating modes and navigate the dive computer.  Safety features such as audible alarms and a high-visibility LED keep you safe by alerting you to rapid ascents or other limits. The i100 dive computer provides all the essential functionality you need, a compact design, and a great price.


Inside you have four operating modes, Air, Nitrox, Gauge and Free Dive. Air Mode is for most of your recreational diving based on 21% air. When you progress onto Nitrox you can select what gas mix you dive on and it will adjust its algorithm. Gauge Mode is the most basic and turns off the algorithms so your computer will just tell you how deep you are and how long you've been underwater. Free-Dive Mode is for snorkelling and freediving with frequent sampling times for more precise records. The i100 even tracks calculations to allow switching between DIVE and Free Modes.

    ABOUT Aqua Lung

    Aqualung have been industry leaders producing a range of diving equipment from regulators and computers to drysuits, wetsuits and masks.

    Aqualung have been producing dive equipment since 1943, started by Jacques-Yves Cousteau and Émile Gagnan who introduced the world to scuba diving and the Aqua-Lung.

    Aqua Lung I100 Computer - Features

    FeatureProduct Specification
    Air Integration
    A dive computer with air integration allows the diver to view the current cylinder pressure on the dive computer display. Some models also display breathing rates. Air integration can be achieved through either a high pressure hose attachment or by using a wireless transmitter.Close.
    The built in algorithm that calculates your NDL and recommends when it's safe to ascend.Close.
    Apnea Mode
    A collection of features developed for free-divers and snorkellers that records how deep you are, how deep you have been and how long you can hold your breath. Some computers include a faster sampling rate, specialized alarms and warnings and specific logbook for apnea.Close.
    Computer Style
    The format denotes the style of the computer, whether it is a standard wrist sized unit with large easy to read display, a smaller watch sized unit which can be worn for every occasion but still packs in all the same features or a console mounted unit which are available with or without air hose integration.Close.
    A PC Interface alllows divers to download previous dive information and profiles for viewing and analysis on a PC or smart device via an app. Depending on the model of dive computer this can include depths, times, alerts, breathing rates, temperatures, etc.Close.
    USB (not included)
    Display Type
    The type of screen affects what and how information can be displayed on a dive computer screen. The simplest is a segment display that builds up characters using pieces of a fixed screen like a digital wrist watch. This is cost effective but limits the use of complex details. A partial dot matrix screen stills uses a section of segment display for numbers but also has a section of tightly group squares that allow for text or graphs to be shown on the screen. A full dot matrix screen completely does away with the segment section of the screen to give full use of the display. Colour LCD screens use the same technology found in TVs to provide a high resolution colour display that gives very clear, vibrant dive information. The technology is more expensive but raises the computer to a new level. OLED screens use a display of tiny LEDs that are very efficient and super sharp. The screen doesn't require a power hungry backlight and can still be seen in very low visibility.Close.
    Gas Nitrox
    A Nitrox or EAN (Enriched Air Nitrox) compatible dive computer allows divers to benefit from the advantages of diving with an enriched oxygen gas mix including extended dive time without incurring mandatory decompression stops during the ascent.Close.
    21 to 100
    Gas Trimix
    A trimix compatible dive computer allows a suitably qualified diver to take advantage of the benefits of a Trimix gas consisting of oxygen, helium and nitrogen. Advantages include extended range diving and reduced narcosis effectsClose.
    Integrated Compass
    An integrated compass helps to reduce additional pieces of equipment that need to be carried. Some console computers are equipped with a standard magnetic compass. A number of computers now feature an electronic compass that is built into the unit itself and operated through the menu system. The electronic compass shows the magnetic North all over the planet by recalibrating the compass for your current location.Close.
    Multiple Gases
    Gas switching allows divers to use more than one gas mix whilst diving. For example, it allows a diver to switch from main breathing gas to an enriched oxygen mix to decompress faster when ascending.Close.
    Rebreather Mode
    A dedicated Closed-Circuit-Rebreather Mode that, depending on the computer, you can adjust and plan high and low setpoints, open circuit bailoutsand other features for diving with a rebreatherClose.
    User Changeable Battery
    Modern dive computers allow divers to safely change the battery themselves with minimal risk of damage through flooding due to incorrect installation. The logbook and memory of previous dives are typically saved during the battery change. Watch sized dive computers typically still have to be returned to an authorised dealer to have their batteries change as special tools and usually needed to open the body.Close.
