Best Digital Diving Gauges
Offering all of the same great features of the Perdix, the Perdix AI uses its large, easy-to-read screen to clearly display the tank pressure as well as your gas time remaining (GTR). The Perdix AI works with any standard AA battery and the transmitter uses a 3V CR2 Lithium.

"I LOVE THIS COMPUTER EXELENT PEOPLE TOO FAST THANKS A LOT :))))))))."
"Comes with a Bluetooth dongle which was good because I think my Samsung Tab Pro has some compatibility issues, no problems using the Shearwater provided dongle. The air integration lets me review my air usage after the fact helping plan future dives."
"It may be overkill for recreational divers, but it is very simple to put into open circuit recreation diving mode, and then it only presents the info that I need."
"This was a good computer, but the Perdix AI takes the cake. I no longer need a computer or have to wait to get to shore to upload my dives. In a matter of a couple of minutes I was able to update the dive profile info and ready to relax. I can compare this to the iPhone, while not the only dive computer capable with all these features, but they just do it so well."
"Absolutely the best dive computer I have ever used."
"This is the perfect dive computer for me, I have used it with the two transmitters on my main tank as well as my pony bottle."
It is a completely modular, rugged computer with a wide UFDS display, which provides the proverbial ease of navigation and Cressi computer menus. Menus and navigation system identical to the rest of the Cressi diving computers, with ease of reading, access to information and model parameter modification. A single button interface makes it effortless to program Air, Nitrox and Gauge modes the first time a diver picks the computer up, and an edge-to-edge, high-definition screen gives large numerical displays in a computer that is still compact and travel-friendly. Enter your model number to make sure this fits.

Or you can check this video at the minute 5:30 where I test going up quickly to test the alarm heads up: [...]. (Note: if you above this note the "[...]" text is because Amazon removed the link, so you will need to search the name above or check my comment below on this review). The only little thing I think it might be a cons, is that the watchband is sort of long and is little annoying (check the screenshot and video) and in one moment I didn't notice that the watchband grabber got released... nothing happens but I could have lost it."
"I bought my Leonardo when I discovered - a couple of weeks before being due to fly out on a dive vacation - that my Oceanic Veo 250 had developed problems with its display. Yes, there is no way to go back if you overshoot your FO2 setting, meaning you have to press the button another couple of dozen times to "go around again", and you cannot hold down the button to rapidly advance (as I was used to with the Veo) because "press and hold" means something different to the Leonardo, but the operation is very straightforward and quite logical once you get used to it. I spent a few minutes per day playing with the Leonardo before heading off on my trip, and never even needed to refer to the "cheat sheet" once I was there."
"Features I'd hoped for: -Basic dive planning. -Depth tracking (max and current). -Dive time tracking. -Temperature. I purchase this based on the reviews and price point, at some point it will be my "back-up" computer, but I love it so far."
"Overall it appears to be a well made piece of gear with easy to understand and use feature but ultimately all those are irrelevent if it is difficult to read the screen."
When Mares introduced the Puck dive computer on the market in 2008, it sent a shockwave rippling through the industry: a super intuitive, easy to use, full-featured RGBM nitrox computer at an extremely competitive price. Enter your model number to make sure this fits.

Find Best Price at Amazon"If you find my review helpful, please click “YES”. Their Claim: Dive computer that meets the most demanding diver’s needs. My Verdict (details below): True (with some missing features). I figured Mares makes great SCUBA products (everything I own is Mares), and this computer has great reviews, so why not go for it? It is an amazingly simple course to follow and taught me everything I needed over about two hours to use this computer with confidence. When you push the single red button, it turns it on (it goes dark after about a minute to save batteries, except when in the water where it’s always ON), and you see the time, with dive time and depth displaying “---“ because you’re in PRE-dive mode. Once you’re ~4 feet under, it turns on the bottom timer and goes into DIVE mode. It has MODE (DIVE and TIME), SET, LOG, PLANNER, PC, & INFO areas. MODE:TIME is for setting time of day, date, etc., that the PRO uses to time stamp your dives. You scroll through the dives, and then HOLD the button to enter that dive log for more information. You’ll find your dive date, Fi02, depth, temp, BT, etc., all quite easily accessible. Go there, and based upon your last dive, SI, desaturation time, etc., it tells you, once you scroll to the depth you intend to dive (40 – 139 feet), how long you can remain at that depth for a no-deco dive. PC is for when you’re hooking it up to the USB cable (which is not included, and costs about $80 online). Unlike the Puck (which also has a cable for downloading your dive log) but cannot upgrade firmware (a real negative about the Puck), the Puck PRO has firmware upgrade capability through this USB cable (which clamps onto the computer at the 3:00 position, which means as Mares makes changes and adds new features (maybe they’ll read my suggestions and add them??? Once you surface, if you stay there for 3 minutes without going back down, it enters the POST-dive mode. It also tells you if you need to make a DEEP STOP during ascent, generally for 1 minute. I don’t exceed 50 feet, so I’ve never had a deep stop warning. If you go above that depth, the countdown timer stops, and you have to go back down to the recommended DEEP STOP depth displayed to start it again. For the 15 foot SAFETY STOP, which it recommends for every dive over 33 feet of depth (2 ATA), it starts a 3-minute timer between 10 and 18 feet. It has a BOTTOM TIME mode, which records your bottom time, depth, ascent speed, and temperature. You can’t select BOTTOM TIME mode if you still have desaturation time left from a prior dive; the PRO won’t allow that. If you go to the surface for LESS than three minutes, and go back down, it starts the bottom timer where it left off, PLUS the surface time. So, if you hit the surface after 22 minutes of bottom time, stay there for 2 minutes to snorkel to another site, and then go back down, it starts at 24” (22” + 2”) minutes, not 22”. The battery is easy to replace, although you should use a new O-ring. But of course, there are big misses with any computer, and the Puck Pro is certainly no exception (I beta test medical software and road bikes, so I am always looking for improvements). It should have one so you can time when you need to meet up (if the dive master says come back in 1:15 minutes, you should be able to set a stopwatch). Bottom timer stops if you’re on the surface for 3 minutes. With the PRO, every time I go back down, that’s considered a new dive. I’d set mine for about 15”, and the bottom timer would restart where it left off when I hit the surface, and NOT add 13 minutes if that was how long I snorkeled for. Because of this feature being absent, I’m forced to return my PRO and am now looking for a computer that has it, such as the Oceanic Veo 3, which is less user-friendly and more expensive than the PRO, but I NEED that feature. With over 500,000 of these medical devices (neurostimulators) out there, Mares is missing the boat by a very wide margin by excluding this feature. It’s MY computer, and I want to be able to change the batteries when I want. You’re out of luck, because resorts don’t have O-rings for every computer. Mares, if you’re reading this review, please let me know if you agree."
"Even though I ordered one puck and one puck pro, I got two puck pros with no additional costs."
"Also the log recall on the device requires a lot of flipping through the menu because I couldn't write down the log items fast enough and the battery saver kept blanking out the screen."
"Very functional."
"Worked fine underwater but found the menu system annoyingly hard to navigate to the info desired."
"- Easy to use, even changing settings while already in water. - Beep alarm is easily heard and not too sensitive. - Back light was bright enough for a Cavern dive. This is the cheapest dive computer I could find and it has everything I need and some."
"Very nice.computer , I have a Uwatec it showed 30 % but it died on the way to my vacation and I have to send it in to replace the batteries., I bought this computer as a back up , and for the money its great I.will not spend onother $1000 for a fancy computer."
"I wore it so the face was on the bottom of my wrist instead of on top like a normal watch as it was easier for me to read but that I believe is a personal preference."
