We tested the Shearwater Teric dive computer. With a beautifully crisp, clear color display in a sleek, air-integrated wristwatch, it was our Testers Choice for watch computers. 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 watch-sized Teric is a departure for a company known for its capable, though somewhat boxy, wrist computers. But the result makes us think that everything Shearwater learned about intuitive operation, readable screens and customizable options with those earlier models was just preparation to make the sexy little Teric. Its four-button operation (one of them a programmable shortcut) is logical and simple – even given the Teric’s rec/tec/ and closed-circuit capabilities. The LED screen is beautifully vivid, and offers an almost limitless degree of customization. In Open Circuit Rec mode, there’s large or standard layout, a choice of what data is displayed and where, and 15 color selections for values, titles, units and menus. There’s a beep and/or vibrate alert as well as silent, and the ascent meter gives both graphic and numeric data. Test divers unanimously rated the safety stop excellent, and the Teric took or tied the top scores for intuitive operation, ergonomics, data display, alternate screen data and onboard log. Stylish enough you’ll actually wear it out of the water, and selected as the favorite by more test divers, the Shearwater Teric is our Testers Choice for watch computers.
