Aqua Lung i770R Dive Computer: ScubaLab Testers Choice

We tested the Aqua Lung i770R dive computer. Combining function and convenience in a compact, comfortable, air-integrated wrist mount, it was a Testers Choice. See full ScubaLab dive computer review here. We tested it at the University of Southern California Hyperbaric Chamber on Catalina Island. We also tested it in the field at Blue Grotto Dive Resort in Central Florida.

We put through a series of simulated dives alongside other computers to gauge the performance of its decompression algorithm. We also simulated dives with rapid ascents and missed deco stops to assess the effectiveness of its alerts and warnings. We evaluated how easy it was to set up and use, how well we could see the screen in different conditions, and how well it presented important data during our dive.

The new flagship of Aqua Lung’s growing computer line, the has a color display that stands out crisply on the deep black background of the nearly 2-inch-wide screen. That earned it an excellent score for readability underwater (though on the surface it hides a bit in the sun). Test divers liked the way it highlights important info by placement and size, giving it the tying top score for data presentation. “Tons of data, but not at all cluttered,” as one test diver commented. Divers also praised its intuitive operation, and rated the 3-button control very good overall, though left-handed divers found the upper-right button a little less handy. The i770R also excelled in its presentation of critical info; rapid ascent triggers beeps and red flashing “TOO FAST,” while excessive PO2 or missed deco brings unmistakable warnings and clear prompts. Compatible with up to 4 transmitters and Bluetooth-equipped, the i770R is a Testers Choice for wrist mount computers.
