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.

Tusa IQ 950 Zen Air Dive Computer Review

Written by Dive Gear Reviews Editor. Comments Off on Tusa IQ 950 Zen Air Dive Computer Review Posted in: Dive Computers, Over $500

For some reason, reviewers call Tusa’s IQ 950 Zen Air a “sleek” wristwatch dive computer, but at Dive Gear Reviews, calling a dive computer “sleek” demands something more than a mere digital sports watch readout. On this point, we profoundly disagree with everyone and think only a serious gear nerd thinks this wristwatch would look good at a business meeting or on a hot date. While the IQ 950 Zen Air is compact, it isn’t “sleek.” Even so, it is a very functional air integrated dive computer.

In terms of data, the IQ 950 is a two-gas computer with three different gas mixture settings and four different dive settings: air, nitrox, gauge and free diving. It uses the Buhlmann ZHL – 16C algorithm with user-controlled safety settings, so a diver can dial the conservatism of the computer up or down as needed. Likewise, a diver can turn the Deep Stop and Safety Stop features on or off. The memory stores the last 24 dives.

The primary displays on the 950 Zen Air include no decompression, elapsed dive time, estimated air time remaining, current depth and water temperature, all of which one would expect from a solid air integrated dive computer. Tusa has also set up the IQ 950 Zen Air with a set of programable alarms for maximum depth, elapsed dive time, dive time remaining, nitrogen load, tank pressure, estimated air time remaining and other factors, and clever use of those alarms can minimize the amount of time spent checking the computer read-out on a dive. The computer can monitor data from three separate transmitters, which is a function with some appeal to divemasters and instructors.

The Tusa IQ 950 has a standard wristwatch computer battery set-up, and has a depth rating of 100 meters. It includes PC support, and data can be downloaded into a base computer.

Sport Diver named the Tusa IQ 950 Zen Air as a 2011 Editor’s Choice, and the guys at Scuba Gear Reports gave it high marks as well, saying “as wristwatch-style DCs go, [it]  is as good as they come.” It also earned high marks from consumers, with the negative commentary confined strictly to the complexity of the buttons and the user interface. That sort of thing is to be expected in a computer with as many features as the Tusa IQ 950, however.
