I just took this dive computer on some deep dives. I had a back up computer and compared them to other people's dive computers. I was at 95ft and other people were hitting 9 minutes till DECO whereas Mares Puck Pro said I still had 26 minutes. That big of a discrepancy makes me question the integrity and accuracy of this dive computer. I checked all my setting. Everything was correct. And everything lined up with my second DC. Except for the DECO timeI didn't try it yet, but it seems to be a great dive computer.Although I bought a new one, it looks like an used because the wrist strap has some melted parts. It's not gonna affect the functions but I expected to get a new product.After MUCH research I decided to purchase this computer for our dive vacation to the Virgin Islands. This was the first dive computer that I have owned, so its hard for me to compare to others. But....I will say that after a reading the manual and a little practice with it, I didn't have any problems or issues. Great product and simple to use!My first dive computer. Does everything I need. Simple to use. Very pleased!Easy to use, accurate and clear to read, even with eyes that wear glasses with a 1.75 magnification on the surface.Works as intended, I like the big display I can see it without my reading glasses.Great product, got it for my 14yo son and it worked perfectly on our recent trip to Bermuda.I have been diving for over 30 years with probably two to three thousand dives under my belt including such places as Belize, the GBR, Raja Ampat, Sharm el-Sheikh, the Mediterranean, Mexican caves, and on and on. I’ve never bought any dive gear till this year, choosing to rent instead. I like to travel super light.After a recent dive trip to Hawaii to do the Black Water and Manta dives off the big island, my wife and I finally decide to buy a few simple things: a dive computer, a mask, and fins. We were tired of sometimes getting crappy equipment wherever we rented and we can still travel light with these items.For a dive computer I wanted something that told me a few simple things: how deep I was, how long I was under, and how long I needed to deco before surfacing. It would be nice if I could use it for nitrox tanks too.I didn’t want bells and whistles, and a thousand dollar dive watch that would take days to learn how to use and with functions I didn’t need. So many of my friends have gotten these things and they never learn how to use them, and then they sit in their garage for a couple years between dives. The only functions they ever needed are the ones I just mentioned.This watch is perfect. Its the google of watches. Simplicity. It does every single thing you need a dive watch to do, is super easy to learn and use, durable, and inexpensive. It’s got a simple screen to look at without numbers all over it that you don’t know or care what they mean. It gives you all the info you need for your dive. You can also change your settings for Nitrox tanks if you want to, very easily.We just came back from Bonaire where we did three dives a day with this watch. Worked perfectly.Whether you’re a novice diver or been diving for years, this watch will serve every purpose you need in a watch. I highly recommend it.great productDer hier angebotene Tauchcomputer wird als Bluetooth fähig angepriesen.Auch fragen in dieser Richtung wurden vom Verkäufer dahingehend beantwortet (siehe oben). Und das ist schlichtweg falsch. Der Tauchcomputer kann es von Haus aus nicht, und der entsprechende Dongle liegt dem Gerät nicht bei.Das war für mich das Hauptkaufkriterium, da Mares die einzige Marke ist, von der man die Daten direkt in das Logbuch der SSI App importieren kann.Zum Tauchcomputer selbst. Dieser ist in Ordnung. Wirkt gut verarbeitet (nicht wie sein großer Bruder Mares Quad). Bedienung geht, wenn auch nicht supertoll mit nur einem Knopf. Aber das sollte man wissen, weil damit geworben wird (Ein Knopf Bedienung).Insgesamt finde ich aber der Tauchcomputer ist das Geld nicht Wert, wenn er kein Bluetooth kann. Und für den hier angebotenen Preis bekommt man auch günstigere Modelle die genau so wenig können.Da nicht absolut schlecht, gebe ich 3 Sterne. Aber das Ding geht zurück. Schade, dass ich das Paket erst erhalten, öffnen und enttäuscht sein musste um das zu wissen.. Aber der Verkäufer ist selber Schuld und kann jetzt geöffnete Ware an den Mann bringen.I bought the original "Puck Pro" two years ago and I love it - it really does everything you may want from a diving computer as a recreational diver. Now I bought this one as a gift for my partner. The price is definitely reasonable compared with some other diving computers that have the same functionalities. The only thing I'm not 100% excited about is the size - I have relatively small wrists and this is actually wider than my wrist! But it's not a watch and I only wear it when diving so I got used to it. All in all great value!When purchased, there is no explanation that you NEED to order the USB>PC adapter in order to charge the unit.I literally have had this watch a month... went to Cuba over Xmas and used it for 4 dives, and the battery is dead, and it is deemed useless until I change it or recharge it.It would be a good starter dive watch (which is what I need), but with no instructions coming with it or a charger, and the “on line PDF” instruction books little difficult to interpret, I have found this NOT to be a good purchase.Will be returning and looking for something else.El producto tiene buena reputacion si me refiero a todos los comentarios positivos, y sin duda esta bien. Pero a pesar del gran tamaño de la pantalla, las cifras son demasiado finitas para que me sea comodo a leer bajo el agua (no adaptado para personas que tiene prebicia). Ademas, la ilumniacion de la pantalla es floja en mi opinion.
