    At the dive site, perform your manual pre-checks on each device before entering the water. Dive Computer Pre-check Ensure that: 1. Suunto EON Core is in the correct dive mode and the display is working as expected. 2. Altitude setting is correct. 3. Personal setting is correct.
  • Page 6 8. All primary and backup gauges for time, pressure and depth, both digital and mechanical, are showing correct, consistent readings. 9. If Suunto Tank PODs are in use, check that Suunto Tank POD is properly installed and the tank valve is open. Please see the Suunto Tank POD User Guide for detailed information and proper use.
  • Page 7 WARNING: Using a dive planner software such as in Suunto DM5 is not a substitute for proper dive training. Diving with mixed gases has dangers that are not familiar to divers diving with air.
  • Page 8 Suunto EON Core WARNING: Do not disassemble or remodel Suunto USB Cable in any way. Doing so may cause an electric shock or fire. WARNING: Do not use Suunto USB cable if cable or parts are damaged. WARNING: You must only charge your device using USB adapters that comply with the IEC 60950-1 standard for limited power supply.

    3.11. Decompression dives When on a decompression (deco) dive you exceed the no-decompression limit, Suunto EON Core provides the decompression information required for ascent. Ascent information is always presented with two values: Ceiling: depth that you should not go above •...
  • Page 21 Suunto EON Core WARNING: NEVER ASCEND ABOVE THE CEILING! You must not ascend above the ceiling during your decompression. In order to avoid doing so by accident, you should stay somewhat below the ceiling. On a decompression dive, there could be three kinds of stops: Safety stop: this is a recommended three-minute stop for every dive over 10 meters (32.8...
  • Page 22 Suunto EON Core If you ignore the alarm and stay above the safe margin for three minutes, Suunto EON Core locks the algorithm calculation, and decompression information will not be available anymore on the dive. See 3.2. Algorithm lock. Decompression display examples Below is a typical decompression dive view showing ascent time and the first required deep stop at 20.3 meters:...

  • Page 23: Last Stop Depth

    NOTE: If the ceiling is broken for more than 3 minutes, the decompression algorithm gets locked. Below is an example of what Suunto EON Core displays during deep stop: With decompression stops, in the continuous ascent mode the ceiling is constantly decreasing while you are near the ceiling depth, providing continuous decompression with optimum ascent time.
  • Page 24 It all comes down to proper control of the expanding gas during an ascent. This is why all Suunto RGBMs use a maximum ascent rate at 10m/minute, which has proven over the years to be an effective protective measure.

  • Page 29: Gas Mixtures

    NOTE: When you have analyzed your gas, you should round the result down when entering it for Suunto EON Core. For example, if the analyzed gas is 31.8% oxygen, then define the gas as 31%. This makes the decompression calculations safer.

  • Page 30: Gas Time

    Gas time information is not visible by default. After customization in DM5, the information will be visible in the lower right-hand corner of the screen. If you have not paired a Suunto Tank POD, the gas time field shows n/a. If you have paired a POD but there is no data being received, the field shows –.

    In another case, if for some reason a diver runs out of gas and needs to use a gas mixture from a dive buddy, it is possible to adapt Suunto EON Core to the situation by adding the new gas mixture to the list. Suunto EON Core re-calculates decompression and shows the correct information for the diver.
