Welcome to Dive Gear Reviews, a comprehensive guide to scuba diving equipment. Scuba diving is an expensive pursuit, so looking up reviews for a particular article of equipment is a wise precaution before investing any hard-earned money in it. However, consumer reviews may or may not be written by an experienced diver, and magazine reviews could be suspect due to the advertising ties of the publication in question. Dive Gear Reviews provides cross-referenced reviews assembled by an expert, making it possible to see at a glance what multiple sources said about a particular piece of scuba equipment. If one magazine loved a scuba regulator or a dive computer, but the consumers hated it, that information will be found here.

Suunto D4/D4i Dive Computer Review

Written by Dive Gear Reviews Editor. Comments Off on Suunto D4/D4i Dive Computer Review Posted in: Between $251-$500, Dive Computers

The Suunto D4 is the most basic of Suunto’s wristwatch dive computers, and Dive described it as the company’s introductory model to its more advanced D6 and D9 number crunchers. The screen is efficient and displays most of the necessary data on the basic page. Depth and no-decompression time occupy the center, an ascent rate graph is situated to the right and a nitrogen graph to the left. Smaller texts on the bottom of the display give out other data, such as water temperature. As for other features, the computer is controlled through four buttons, can be set for Nitrox or free diving, and has three altitude settings. The computer’s basic algorithm is semi-conservative, but by playing with the settings this can be adjusted to an either more conservative or more liberal footing. Leisure Pro users were quite satisfied, giving this basic computer a 4 1/2-flag rating.

In 2011, Suunto introduced an air-integrated version of the D4, the D4i. The only real change is that tank pressure data is sent to the wristwatch computer from a wireless transmitter attached to the regulator. The computer uses that data to provide read-outs of not only tank pressure, but also an estimate of remaining air time.
