Go online and download the Suunto DM5 dive-planning and recording app, and you can now connect your dive-computer to your PC or Mac to download detailed dive information, using the same USB cable you used to charge the Eon Core’s battery.
Suunto DM5 dive planning and dive log screens.
So far, so what, you may say, but the DM5 app also allows you to turn on the settings for Gauge mode, or diving with multiple gases, or using trimix, or even have your Suunto act as a backup in case your rebreather throws a hissy fit. In fact the DM5 needs to be considered as part of the Eon Core package when you make your buying decision. It’s free to download.
The Eon Core unit itself has some basic dive-planning functionality built-in, allowing you to plan a square-profile single-gas dive taking into account the size of your gas supply and your breathing rate, assuming you’ve set them up in the computer.
However, the DM5 app provides you with a much wider range of tools, including multiple gases and even a choice of three Suunto decompression algorithms.
The app will also automatically check that your Eon Core has the most recent firmware installed, and will prompt you to upgrade your computer if not, which is a simple one-click-and-wait-until-it’s-finished process.
The idea is that you can buy an Eon Core as a recreational newbie without being put off by complexities you don’t need, but then it can be updated with new firmware to make sure it’s current as long as you are.
Then, if you’re drawn to the dark side, it’ll go with you almost as far as you want to go.
Take it diving, and the Eon Core sits nicely on the wrist. It’s big enough without being over-sized, and the slimline design should keep it at least partially protected from knocks.
A stick-on protective film to provide extra protection against scratches for the mineral-glass screen comes in the box, and you can buy extras if you need them.
The strap is plenty long enough for even the thickest arm and drysuit combination, and it has closely spaced slots so that you can tighten it exactly to your liking and make sure it stays put.
I’ve already said that I rate the readability and the layout of the screen very highly, but it’s worth repeating.
To be very critical, the screen is a bit directional in brightly lit water, but a turn of the wrist restores readability. And if anything that strap is so long as to be annoying. A replacement bungee arrangement is available for around £21 but being cheap, I’d put up with the strap until it broke, then get the bungee.
If the strap on my original Suunto Solution is anything to go by, that could be a long time.
