Simple to use

It is an easy-to-use dive computer. It comes with a user manual that clearly explains how to set up the computer, and it’s so simple to operate. The buttons are large enough for gloved hands, and there are no codes or combinations that you have to remember. The screen is big enough for anyone with old eyes like me!

This Aqua Lung i300c computer is a great combination of a watch and a console system. It has all the basic functions of a dive computer system, but it’s also simple to use. This unit is easy for both new and experienced scuba divers.

It has a backlight button which makes it easy to read at night or low light conditions. It has a countdown timer that beeps every minute until your time is up on your dive; this feature can be turned off if you prefer silence while diving deep into the sea where no one else can hear it anyway!

The battery charger that comes with the i300c has two prongs on top which fit perfectly into my power strip at home without any adapters needed! I don’t know about you but when I travel overseas it’s always hard finding things like this because they come in different shapes and sizes depending where they were made (or so I’ve heard).

More safety at depth

The i300c is a well-designed dive computer that provides you with more visibility, contrast, information and comfort. The large display means it’s easy to read while diving, while the lighted screen means that even if you’re diving in low light conditions (like caves) the screen will still be visible. The wrist strap also allows for greater comfort when wearing your computer so that it doesn’t get in the way of your dive experience.

The Aqua lung i300c’s Versatility

As a dive computer, it is a versatile device that can be used in basic open water dives as well as being very effective in advanced diving situations.

It is designed to be used by recreational divers who want more information about their dives than simply time underwater or depth of dive. It has many useful functions including multiple gas choices, dual time zone capability (local or UTC), data recording capabilities (including maximum depth reached), full decompression tables including altitude adjustment factors for air/nitrox/heated water dives, customizable settings such as temperature compensation or altitude decompression calculations, intuitive menu system and backlight modes which allow you to choose between high intensity lamp mode or low intensity lamp mode


The quality of the Aqua Lung i300c makes this dive computer an excellent choice for both new and experienced scuba divers.

It is a great dive computer for both beginners and experienced divers. This is mainly because it can be used in a wide variety of diving conditions, from basic open water dives to advanced technical dives.

It has been designed with simplicity in mind, making it very easy to use by both new and experienced scuba divers alike. It’s also very light weight which means that you will barely notice it on your wrist when you’re diving. The display uses large numbers so that even when wearing gloves you can still read the information clearly on the screen and there are 9 different languages available including English, Spanish and French amongst others.

The Aqua Lung i300c digital wrist dive computer is a great choice for divers who want to have a compact, lightweight, easy-to-use dive computer on their person at all times.


It comes in 5 bright colors: black, red, blue, green, and yellow. The diver can choose the color that suits their style and it will be easy to read in any light because the numbers are large enough to see from afar.

The Aqualung i200c and i300c dive computers are both mid range models that offer a wide range of features. Both models have a user-friendly interface, and both are capable of storing a large amount of data.

Here is a comparison table between the Aqua Lung i300C and i200C dive computers:

As shown in the table, both the Aqua Lung i300C and i200C dive computers offer similar dive modes, max operating depths, backlighting, and audible alarms. However, the i300C has Bluetooth connectivity, allowing it to sync with the DiverLog+ app to wirelessly upload dive data and provide firmware updates. The i300C also has a longer battery life and dive log capacity than the i200C. However, the i200C is more affordable, making it a good option for recreational divers who do not need advanced features. Ultimately, the choice between these two dive computers will depend on your specific needs and budget.
