Super sharp and clear display, perfect ergonomics and user-friendliness, all around capable of multi gas and free diving. 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. Ean (nitrox) from 21% to 99%.
