EON Core Computer

Brand: Suunto

Model: EON Core Computer

SKU: 70615-1

Please note: This item cannot be shipped outside the European Union - learn more

The Suunto EON Core Dive Computer is a bright, intuitive colour screen wrist computer made for the travelling diver who wants an easy to under stand computer that they can read in all conditions.  The colour screen can be fully customised to your needs and the Core's software can be updated at a later date by connecting to DM5.

A lighter and more compact version of the popular EON Steel Dive Computer but with many of the same features and benefits the Core sits just below the Steel in the Suunto range.  Inside the Core is much the same as the steel and has a similar structure but it is made out of lighter materials.


Colour Screen

The TFT LED screen has a full range of colours that make it intuitive to read, even at a glance.  You can change the brightness of the screen to make it easier to read in any environment.

You have a choice of display formats from graphic, numerical and a new prominent that either show you pure numbers for depth, air remaining etc. or circles for a more natural view or a mixture of the two.  As with the Eon Steel you can create and organise multiple pages or screens that you can flip through during the dive for different information.



Along with the choice of screen layouts you can change the orientation of the computer so you can invert the screen to wear it on either arm with the buttons facing either direction.  You can also fit an optional bungee strap for a flexible mounting option.

Suunto EON Core Computer - Features

FeatureProduct Specification
Air Integration
A dive computer with air integration allows the diver to view the current cylinder pressure on the dive computer display. Some models also display breathing rates. Air integration can be achieved through either a high pressure hose attachment or by using a wireless transmitter. Close.
x10 Wireless (not included)
Apnea Mode
A collection of features developed for free-divers and snorkellers that records how deep you are, how deep you have been and how long you can hold your breath.

Some computers include a faster sampling rate, specialized alarms
and warnings and specific logbook for apnea. Close.
Computer Style
The format denotes the style of the computer, whether it is a standard wrist sized unit with large easy to read display, a smaller watch sized unit which can be worn for every occasion but still packs in all the same features or a console mounted unit which are available with or without air hose integration. Close.
Display Illumination Type
Dive computer displays typically have one of two illumination types. Phosphorescent displays glow when charged by light such as torchlight, it will continue to glow until its charge is depleted or it is recharged. Dive computers with a backlight facility use an internal light source to illuminate the display for a short period of time before turning off to save the battery. Close.
Display Type
The type of screen affects what and how information can be displayed on a dive computer screen.

The simplest is a segment display that builds up characters using pieces of a fixed screen like a digital wrist watch. This is cost effective but limits the use of complex details.

A partial dot matrix screen stills uses a section of segment display for numbers but also has a section of tightly group squares that allow for text or graphs to be shown on the screen.

A full dot matrix screen completely does away with the segment section of the screen to give full use of the display.

Colour LCD screens use the same technology found in TVs to provide a high resolution colour display that gives very clear, vibrant dive information. The technology is more expensive but raises the computer to a new level.

OLED screens use a display of tiny LEDs that are very efficient and super sharp. The screen doesn't require a power hungry backlight and can still be seen in very low visibility. Close.
Gas Switching
Gas switching allows divers to use more than one gas mix whilst diving. For example, it allows a diver to switch from main breathing gas to an enriched oxygen mix to decompress faster when ascending. Close.
Integrated Compass
An integrated compass helps to reduce additional pieces of equipment that need to be carried. Some console computers are equipped with a standard magnetic compass. A number of computers now feature an electronic compass that is built into the unit itself and operated through the menu system. The electronic compass shows the magnetic North all over the planet by recalibrating the compass for your current localation. Close.
Nitrox Compatible
A Nitrox or EAN (Enriched Air Nitrox) compatible dive computer allows divers to benefit from the advantages of diving with an enriched oxygen gas mix including extended dive time without incurring mandatory decompression stops during the ascent. Close.
5 to 99
PC Interface Compatible
A PC Interface alllows divers to download previous dive information and profiles for viewing and analysis on a PC. Depending on the model of dive computer this can include depths, times, alerts, breathing rates, temperatures, etc. Close.
USB (included)
Rebreather Mode
A dedicated Closed-Circuit-Rebreather Mode that, depending on the computer, you can adjust and plan high and low setpoints, open circuit bailoutsand other features for diving with a rebreather. Close.
CCR, Fixed Point
Trimix Compatible
A trimix compatible dive computer allows a suitably qualified diver to take advantage of the benefits of a Trimix gas consisting of oxygen, helium and nitrogen. Advantages include extended range diving and reduced narcosis effects. Close.
0 to 95
User Changeable Battery
Modern dive computers allow divers to safely change the battery themselves with minimal risk of damage through flooding due to incorrect installation. The logbook and memory of previous dives are typically saved during the battery change. Watch sized dive computers typically still have to be returned to an authorised dealer to have their batteries change as special tools and usually needed to open the body. Close.
No, Rechargeable

Nice Suunto Computer

The EON core is the latest Suunto colour screened model. Screen is sharp and layout can be customised to show elements you are interested in (good) and can have as much or as little data as you wish depending on your preference regarding size of figures. One point on this, in bright sunlight even in the UK, you will really need to run full brightness and this will reduce battery life to no more than 15 hours.

Customisation is done with DM5 on Mac/PC only. You cannot do this on the Movescount app.

This is a gas switching computer supporting plenty of gasses, Nitrox/Trimix. DM5 to enable /disable trimix for example.

Things possibly to note:

- If you are doing say 26% back gas and 50% deco, the ascent time includes the use of the 50%, NOT the ascent time for the gas you are on and then when you switch shortening stops.

- Gas switch is easy enough, but pressing the button does not instantly switch when it says change gas if you program two, you have to enter the menu and choose select for the gas you want - you might have 3 or 4 you see (well I guess that is why).

- The plan function cannot plan for the deco gas, only standard single gas diving (this seems poor for a computer of this cost) - you have to use DM5 for this planning.

- charger cable is USB and of course custom and expensive

- Fused RGBM is notably LESS conservative by default than a Gallileo.

Nice computer, but possibly for the tech diver it lacks a little - but alot cheaper than OSTC/Shearwater etc.

Great Screen - Easy To Use

I've bought Suunto computers for several years now as I like the general quality and usability of their products. Unfortunately though as I get a little older my eyesight is getting a little worse and I'm finding it hard to make out the info on my D6, so it was time to look for an alternative. This computer fits the bill perfectly. The screen is fairly big, bright, colour coded, and easy to read. It's also really easy to navigate. A big bonus is that you can easily change the display layout in DM5 on your Mac or PC, and create display custom settings. This isn't a gimmick, it really does make reading and navigating the computer much easier.

Overall a great computer and perfect for recreational diving.
