Suunto Eon Core

The compact Suunto EON Core is designed as a dive companion for both beginner divers and experienced divers looking to explore new depths. Underwater, the key data of your dive is easy to read on the clear colour display with large, bold digits.

Easy to read: All important dive data is visible at a glance on a clear, well-readable screen. The high-contrast, large digits and letters remain legible even when diving in murky water or at night.

Grows with you: The Suunto EON Core is ready to use right out of the box, and with the Suunto App you can easily personalise your own dive modes. Several view styles are available, and you can choose which details you want to see while diving. When personalising your dive modes, you can also set your gas, algorithm, and dive alarm preferences. Software that's easily updatable by the user via SuuntoLink keeps the Suunto EON Core a reliable dive partner for years to come.

Compact and comfortable: The composite housing is light and comfortable to wear, either on the wrist with an elastomer strap or bungee, or with a drysuit. The display is protected against scratches by durable mineral crystal glass, and the large buttons are easy to press with or without gloves. The Suunto EON Core is available in Black, White, and Aqua Blue, and charges conveniently via USB, offering 10 to 20 hours of diving time on a full charge.

Connect and transfer: Track your tank pressure conveniently right on your wrist, with up to 10 tank pressures displayed on the watch at once when using a Suunto Tank POD. Connect your Suunto EON Core to the Suunto Tank POD before your dive, and tank pressure is transmitted wirelessly to your display, with the device able to pair with up to 20 different Tank PODs. Transfer your dive logs easily via Bluetooth to your phone. In the Suunto App you can relive your dive adventures and share them with others, build a comprehensive dive history, and enrich your dive logs with short stories, comments, and the dive location. Review and analyse your full dive data, including dive time, maximum depth, device settings, and gas consumption (when using a Suunto Tank POD). The Suunto App is available on the App Store and Google Play.

Suunto Tank POD: Enjoy more comfort and safety with the wireless tank pressure transmitter, compatible with up to 20 different tanks.
