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-850 DC Sapience II Dive Computer Review

Written by Dive Gear Reviews Editor. Comments Off on Tusa IQ-850 DC Sapience II Dive Computer Review Posted in: Dive Computers, Over $500

Tusa’s IQ-850 Sapience II is a wristwatch dive computer of the big, square console style, as opposed to the discrete wristwatch style. The dive computer also builds on the old IQ-800 model, so many of the design features are already well-proven.

The first thing a diver should notice about the IQ-850 is that it is not even remotely as clunky as it looks. Despite the big square display, the IQ-850 is a product of thoroughly modern technology, so that display is thin despite covering a large surface area. Another very up-to-date feature is the vibration alarm, which was exclusive to the IQ-850 at the time of its release. Basically, you can set the computer so it vibrates instead of beeps, much like your mobile phone. This rounds out the visual and audio alarm systems, for maximum flexibility.

The computer has four basic modes: air, nitrox gauge and time operating (Scuba Diving reported only three, but the manual confirms the time operating mode). As the modes imply, the computer can handle nitrox computations of up to 99%, and is programmable for two gas modes and can switch between them in mid-dive. It has automatic altitude adjustment, can download data to a PC and store data from 25 dives. The Sapience II also displays a no-fly icon automatically, displays data in big characters and digits (as one might expect from the big screen), and that screen is back-lit. The basic algorithm is moderate-to-conservative, but it can be adjusted up or down by the user with three settings. The battery is a CR2032 coin-type battery, and is user-replaceable.

Average Price: $775
