Mares Smart Wrist Scuba Dive Computers PRODUCT DESCRIPTION The dive-mode display is well thought out and easy to see and understand, with data for depth, NDL, dive time and temperature, along with a tissue-loading bar graph and ascent-rate indicator. the alternate-dive-screen data include maximum and average depth, gas mix, oxygen-toxicity level and current time. The smart’s two-button system is easy to navigate and logical in dive mode, in which the upper button modifies the top row of the display while the lower button toggles through alternate displays on the lower right. Test divers found the system very intuitive. the backlight is good, as are the visual and audible alarms. A large “slow” warns of too-rapid ascent, and there are warnings for MOD and oxygen toxicity. there’s also a tissue-loading bar graph on the right, although some divers found this a little hard to see. Divers found the smart among the easiest wrist- watches to read in bright sun, and they also liked its surface-interval countdown timer. In our chamber dives, the Smart’s RGBM algorithm was about middle-of-the-road in conservatism. •Super sharp and clear display •Perfect ergonomics and user friendliness •All rounder capable of multigas and freediving Quintessential: representing the most perfect or typical example of a quality or class. What happens when you add the superior sharpness of segmented characters, clarity of a perfectly laid-out display, and top it off with ergonomic advantages of two buttons? You get Smart, probably the smartest computer on the market. Smart replicates the excellent display of the Puck Pro, adding an additional button, buttons repositioned to the side, all packaged into a much slimmer profile. On the surface, adjust your nitrox settings or view your logbook with ease. Underwater, you can manage alternate depth information (top row), completely independent from the ancillary information displayed in the bottom row. We’ve finished it with a two-color strap and unique design, making this the perfect companion for your time away from diving.
