Aqua Lung has packed a lot of features into a dive computer scarcely larger than a sports watch. The three-axis compass, advanced pairing with a mobile app and social sharing, bright display, and useful features make this an excellent dive computer from a legendary brand.

Aqua Lung has been making scuba gear for over 70 years and the care and attention to detail shows in the i750TC. The PVD finish is durable, resistant to wear, and does not reflect sunlight in shallow water.

Data retention stores your dives and settings even when you are changing the battery.

The bright OLED color screen is vivid and easy to read, and the intuitive operation is easy to understand.

This is a dive computer simple enough for a beginner but versatile enough to grow with a diver as they become more advanced.

The bragging rights on the i750TC are definitely the OLED display, with variable brightness, rich colors, and an easy-to-read, easy to navigate operation.

Three buttons make screen navigation a bit faster than two, which is a nice feature.

What We Like

The Aqua Lung i750TC has all the features beginning and intermediate divers need, in an attractive. compact design. The bright display is clear and easy to read, and the combination of visual color warnings with audible alarms keeps safety simple and clear.

It uses the popular Pelagic Z+ algorithm, which is less conservative than some algorithms, lengthening dive times while still easing safe ascents. While some feel that Pelagic Z+ may not be conservative enough for brand new divers, it’s worth remembering that it’s been used safely by divers for decades, and shouldn’t be a cause for concern when followed properly.

What We Don’t Like

The screen does not manage sun glare well and can be difficult to read in bright light, even when underwater. Adjusting screen brightness is important, and not intuitively done within the interface. Divers should refer to the manual ahead of time to learn how to adjust it.

The related DiverLog app is not free, and not very well reviewed, so some of the device-driven capabilities and social sharing features of the Aqua Lung i750TC may not work as well as claimed.

Who Is The Aqua Lung i750TC Designed For?

The Aqua Lung i750TC is simple enough for beginners but advanced enough for experienced divers. The compact design is attractive, with a tough, stealth-mode PVD finish. The range of diving modes, the 3-axis compass, and tank-switching capabilities make this a versatile dive computer with an attractive style

The price is fairly high, reflecting the advanced technology of the i750T. It may be a bit too expensive for a beginner, but the i750T is durable enough that it can grow with a diver as their skills advance, and for many, it may be the only dive computer they ever need.


Frequently Asked Questions

Can the i750TC be paired with other brands of transmitters?

What type of batteries does it use?

Can I monitor my buddy’s air supply as well?

The Bottom Line

The Aqua Lung i750TC is a very good dive computer, with attractive features and high-tech capabilities that will appeal to people who want to plan their dives from their laptop or mobile device.

It’s simple to use, but robust enough, and has the capabilities that will take a recreational diver from beginning to intermediate or advanced. It may seem expensive, but it’s an investment that could pay off for years to come.

  1. Love my I750 but at100% brightness it hard to see and pod keeps dropping out. Have to rest it . When I first bought it it was amazing could see everything easy but now it harder to see. Cleaned after every dive. Any suggestions.

  2. I have a i750tc, it has about 45dives logged and the screen started to have some vertical lines and now there is no more image on the screen, I would not reccomend this diving computer because screen is hard to read if the sun is up(when the screen works) too cheap hardware for the price you have to pay
