The Suunto EON Core is the latest dive computer to join the elite ranks of Suunto's diverse range of dive computers, bringing many of the features found in the premium EON Steel but in a smaller and lighter format. Smaller and lighter it may be, but it doesn't lack in capability with Air, Nitrox, Gauge, Trimix and CCR dive modes which use the Suunto Fused RGBM decompression model. The EON Core is compact and comfortable to use. Much of the size difference between the EON Core and Steel is to do with the thinner and lighter reinforced composite housing that has a depth rating of 80m, more than ample for recreational divers. The three push buttons have also been moved to the side of the computer to make the EON Core fit better on the wrist for divers wearing thinner wetsuits or rash guards. Whilst the Eon Core is fitted with an elastomer strap it is also supplied with a bungee strap kit. The EON Core still features the straightforward and easy to read full-colour LED-backlit display that features customisable screens with four pre-configured display modes that provide large digits and dive information. The screen automatically rotates depending on the orientation of the dive computer. The screen also makes excellent use of the 3D tilt compensating compass that makes navigation so simple. The Suunto Eon Core uses a rechargeable lithium-ion battery that provides 10 to 20 hours of diving from a full charge. Charging is kept simple and can be recharged from any USB socket with varying speeds depending on the port output. The Eon Core supports wireless air integration and is capable of pairing with up to 10 Tank Pods. The Core can also be connected to a PC / Mac using Suunto Dive Manager for data transfer and software updates or to a smart device via Bluetooth for dive profile synchronisation using the Suunto Movescount app.

I really like this computer. On my first dive I used the factory settings. It was easy to use and intuitive. The menu system is easy to use. I like the fact that I can customize to my needs. There are, however, some key enhancements required:1. The ability to view two tank pressures simultaneously on the same display setting. For a computer of this level this is a big omission in my view.2. For older divers who struggle to read things close up, the size and clarity of the all the headings and readings on the display is critical.

It is the reason I bought this in the first place - my logic was that due to it having a bigger display compared to a watch computer, I would be able to read everything easily. Well, I was wrong. Firstly, the headings for each piece of info displayed (e.g, dive time, max,m, tank, bar etc.) is too small and dull in colour to read underwater. Even on the brightest setting. So, basically I have to memorize where on the display all the relevant info is. Secondly, the smallest of the numbers displayed are just that, they are small. Despite a nice big screen, I have difficulty reading in prominent view the bottom right number. Considering that this is where either the no deco or tank pressure (depending how you have set it up) is found, it is not great. Unlike the other numbers, which you can read at a glance, this one I cannot. I have the same issue with smallest numbers on the other views - classic etc. PS. I don't really feel like getting and paying for a prescription mask just for this. I have no other need for a prescription mask.3. Glare off the screen when near the surface. Whilst the first two issues raised above should in theory be able to be fixed with a firmware upgrade, this may be hardware related.Otherwise, a great product and lets hope some of these improvements will come via a firmware update soon.

I really have enjoyed this computer, and would like to keep enjoying it. However, my not-so-complex advancements in scuba are outgrowing this computer. Half of my diving is in the side mount configuration and running two Tank Pods for reporting the same gas is not currently an option. I've considered "work arounds" but that would only lead to the possibility of dangerous confusion. There are computers on the market that have a "Side Mount Mode" that allows their transmitters to report two tanks containing the same gas without confusion. I am looking at them! Suunto, please produce a firmware solution to accommodate Side Mount Mode!

My first short dive trip consisted of five dives, all on air, over six days with two no-dive weather days in the 6.After studying up and practicing with the computer for a few sessions before the trip I had no difficulties popping through the menus to configure as needed on the shore, boat or even when floating at the surface. That is mostly unnecessary to do, I was just putting it and me through the paces to gain complete competence in my new computer.I found that on a sunny day on a boat or at the surface the full bright setting is necessary to see the details on the screen. Practically speaking I feel that full bright will be my “default” setting at all times. That dramatically impacts estimated battery life, however, I still completed all five dives and a fair ... MoreMy first short dive trip consisted of five dives, all on air, over six days with two no-dive weather days in the 6.After studying up and practicing with the computer for a few sessions before the trip I had no difficulties popping through the menus to configure as needed on the shore, boat or even when floating at the surface.

Practically speaking I feel that full bright will be my “default” setting at all times. That dramatically impacts estimated battery life, however, I still completed all five dives and a fair amount of dive log and planning work over the six days without a recharge. I think that is very adequate for my expectations. All of the dives were simple except one guided full-limit deep dive. I was very impressed with how the computer managed my time and stops after descending to 130 ft of depth to a zero no deco time. It directed me to do two deep stops and a mandatory safety stop. The audible alarm to prompt me on these procedures was easily heard. The screen displays were easily read and interpreted for easy compliance.The compass feature was straight forward and easy to use.It did a fine job of tracking and reporting my surface time between dives, and through days of no diving, to provide for my long-term protection.I was able to use the Tank Pod only on the surface before I left for the trip, so it’s use was incomplete. However, in testing, it paired easily and reported pressure intuitively. I’m looking forward to using it at depth.I will reevaluate my rating as I complete a multi-gas switching dive with use of the Suunto Tank Pods accessory.I chose the EON Core because my intentions are to train to PADI Tech 45 standards and this computer is well designed and intended for that flexibility. However, most recreational divers will likely be well served by one of Suunto’s lower cost, simpler computers. Since they run the same algorithm there would be no compromise in safety.Overall I am very happy with the EON Core’s performance.

First off, I love it, it’s easy to use and has tons of options to customize for divers more advanced and adventurous than me.There are a few caveats though:Battery life. It’s around 19 hrs of screen-on time, which is usually fine for me for an entire week long trip plus scrolling through logs and fiddling around in between. Just be aware you won’t be leaving this thing in your bag and slapping it on at the dive site. You’ll want to remember to charge it between dive trips. The charger is also proprietary so don’t forget it!It’s VERY conservative out of the box. It showed me longer stops and shorter bottoms times than my buddies oceanic did. I understand this can be tuned to your liking however, so that shouldn’t be a problem long term.Size. wearing this on ... MoreFirst off, I love it, it’s easy to use and has tons of options to customize for divers more advanced and adventurous than me.There are a few caveats though:Battery life.

The charger is also proprietary so don’t forget it!It’s VERY conservative out of the box. It showed me longer stops and shorter bottoms times than my buddies oceanic did. I understand this can be tuned to your liking however, so that shouldn’t be a problem long term.Size. wearing this on your arm over a wetsuit is fine, and I didn’t notice the big size until I finally took it to the tropics. Then I realized how chunky the thing is. It didn’t like to stay put on my bare arm when I switched to a short suit. I ended wearing it tighter than usual to get it to cooperate, which worked out okay.You’re not going to wear this anywhere except while diving. It doesn’t work as a real world watch, and it looks like you’ve got a full size iPhone strapped to your arm. Watch-style computers have the market cornered on wearability.The pros:The color display is super easy to read, the alarms are audibly but not overly annoying (unless you ascend too quickly) and I love how the relevant information at the time takes over the largest portion of display.When you’re at the bottom, you get a big circle ticking down your NDL time remaining thats green when its full and turns red when it gets low. When you hit your safety stop after ascending to 15 feet, it changes to a countdown in minutes and seconds that starts red and gradually turns green as you are considered “safe to ascend”Really lovely compass and bearings, timer functionality is great. All around really recommend it if you don’t quite want to fork over the $$$ for a shear water but you want something thing high-end.Overall I think it’s great for most people. My girlfriend tried it on and it was just too big for her arm, so smaller divers should try it out before selecting it.
I have been diving for many years now. I was taught how to multi level dive from the tables to put it into perspective. I currently hold Dive Master cards in PADI & SSI and am working towards my completion of SSI OW Instructor. The first computer I have owned tracked depth, time and Nitrogen... that's it. I was diving another comparable computer that I enjoyed using very much. It started as my wife's but it has a very busy layout display and quickly overwhelmed her so I inherited it. I put 70 dives on this it over the last 6 months or so. I recently switched to the Suunto Eon Core where I quickly fell in love with the layout options, customization options and the quality of the display.

I recently switched to the Suunto Eon Core where I quickly fell in love with the layout options, customization options and the quality of the display. The bungee attachment is a must in my opinion also. Wearing a wet suite I find you have to cut off circulation to get it to hold at the surface and then you still have it flopping around your wrist at 50 ft. But my absolute favorite thing about this computer is the real time feedback of my SAC rate. I know if and when I am working a little too hard during the dive now and can maximize my bottom time better with this awesome feature.
I have had it a year now and it is easy to read for my (older) eyes. It is also pretty conservative, which I appreciate, though you can make it more aggressive if you wish.One question: when I share a dive, the graph does not seem to represent my actual profile. Also, what is the vertical depth measurement on the right side tell me (for instance, on a 96’ dive yesterday, that vertical measurement says 29’)?Finally, when I download my dives to an iPhone or iPad, it gives my consumption in l/pm, even though my computer is set on imperial and it shows in imperial measurements on my Mac laptop.But, I love this computer and it’s options for customization. I have recommended it so several others.
I have used EON Core for around 30 dives including night dives and murky waters. I like very much that it's so easy to read the bright coloured screen, and I like that the layout of screen can be customised.Air integration is a nice feature, especially in poor light conditions where it is easier to read EON than my SPG.Unfortunately air integration on this computer is of no real use with side mount configuration. Even though you can connect simultaneously to several tanks, you're only able to read from one tank at a time.So unless Suunto will fix this in a firmware update (hopefully soon), I'll have to replace it with something else.
I purchased this computer for my son who was certified this summer. I used to have one, but gave it to my daughter when I purchased an EON Steel for the larger screen. Now both kids have the same type of computer, so everyone is on the same algorithm. Love the computer's intuitive menu and how easy it is for newer divers to use, plus the depth of features that will support the kids as they advance in their diving journey is great. This computer works just as well in a drysuit and thick gloves in Puget Sound as it does on warm water trips. I highly recommend it.
Positive:- compact- rugged- backlit color screen- rechargeable batteryNegative:- you can't really trust the battery charge assessment; if the computer claims it has 3 hour left on the battery it's likely that it's less than that- if your computer runs out of power during a dive, it's LOCKED OUT for the net 48 hours! I know the reason behind this (computer doesn't know what you did during the dive) but having it locked out for 2 whole days makes it completely useless.Suunto needs to fix this... either by adding the possibility to "fill in" manually the dive details, or at least add a warning which informs the divers that their physiological state will be "reset" to "no dive" and that they need to acknowledge this and assume responsibility before they ... MorePositive:- compact- rugged- backlit color screen- rechargeable batteryNegative:- you can't really trust the battery charge assessment; if the computer claims it has 3 hour left on the battery it's likely that it's less than that- if your computer runs out of power during a dive, it's LOCKED OUT for the net 48 hours!

Most excellent purchase. I like this computer. 63 dives on it. I'm a recreational diver so I cant speak to all that supposed tech diver kinda stuff. But in the tropical waters of florida it works fine for me. you do have to charge it every night. Not a high capacity battery. Not a problem for me. Great compass. Transmitter is a bit big at the bottom so I used a XS scuba hp port extender now it clears the hoses fine.
