Mares Smart Dive Computer

  • £249.00

Smart is the perfect example of the qualities of a good scuba diving computer. Perfectly set out display with sharp and clearly visible characters, an ergonomic profile with two buttons for very easy navigation. "Smart" is the most "intelligent" dive computer on the market.

Smart is the classic dive computer! Superb clarity of subdivided characters, perfectly arranged displays, ergonomic buttons and slim outlines all combine to give you the smartest computer on the market!

The Smart Scuba Dive Computer has a perfectly clear display and an exemplary design. Extremely comprehensive and ergonomic, it is also suitable for multimix and free diving. On the surface, you can adjust the nitrox settings, or view the logbook at a glance. On the other hand, underwater, the Smart allows you to switch between depth information (shown on the top line), which is completely independent of the complementary information shown on the bottom line. The middle row is dedicated to information on the decompression state.

The buttons have been repositioned to the side, thus favouring a truly compact, ergonomic profile and providing immediate performance. The upper right button manages data regarding the maximum depth, average depth and maximum depth reached by the gas. The lower right button, on the other hand, adjusts the field next to the dive time, providing temperature, oxygen percentage, CNS, time of day and stopwatch. The time of day is given a 4-second timeout, after which the dive time will be displayed again for safety. The battery has a guaranteed autonomy of 2/3 years (depending on the number of dives), and can be easily replaced independently by the user, without any technical support. Equipped with a two-tone black/white and black/grey strap.

Great Service!

Ordered a couple of dive computers mid-afternoon, they were sent out the same day, arrived quickly and well packaged. Good price too!

Dive computer itself came set up well and pretty much ready to go. Well made and should take a battering, clear screen, and although a bit big for every day watch duties isn't overly cumbersome. No instruction manual in the (all cardboard) box, but easily found on the Mares website.

Recommend this place fully, they're new to retail so don't have the online presence of some others, but the service is great!

Very professional, friendly and efficient service.

5 Star. The internet is flooded with online retailers especially in the dive/Watersports industries but if you’re looking for a company that goes that little bit further speak with Russell at Water World Sports. His website is up to date, his communication is second to none, always ready to answer your questions and return with an answer promptly. My Mares computer arrived next day, securely packaged. Russell’s aftercare email to make sure everything is ok sets them apart from others. It’s a competitive market out there but if you want a hands on, professional service then look no further. Thanks Russell and team.
