Watch the video on YouTube.

To customize Suunto EON Steel:

  1. Download and install Suunto DM5 from
  2. Connect your Suunto EON Steel to the computer with the USB cable.
  3. In the devices window, select Suunto EON Steel.
  4. Select the Customization tab. You can create new dive modes and modify existing ones.

When creating or modifying dive modes, you need to synchronize the changes with your Suunto EON Steel before disconnecting the USB cable to save the changes to your device.

Customization is divided into four categories:

  • Dive mode name
  • Dive algorithm
  • Gas settings
  • Customize views

Dive mode (name)

Maximum length of the name is 15 characters. Use something short and simple that helps you identify easily the features and information that you have customized on this mode.

Dive algorithm

You can select to use Suunto Fused™ RGBM or no algorithm (see Suunto Fused RGBM). If you select no algorithm, Suunto EON Steel functions as a gauge (bottom timer) in that mode. If you select Suunto Fused RGBM, you have two additional options: personal setting (algorithm conservatism) and altitude setting.

Gas settings

Here you configure what you see under the Gas(es) menu in Suunto EON Steel. The multiple gases option can be turned on or off. Turn it on to be able to dive with multiple gases. When turned off, the gas menu is simplified and easier to use with only one gas.

Helium can also be turned on or off. If you turn this off, you cannot see the helium component for any gases.

The gas max pO2 setting can be set to manual or fixed. The fixed option means that the selected value is used for all gases and the option to manually edit them in the Gas(es) menu is disabled. When manual is selected, you can edit the gas max pO2 for each gas individually in the Gas(es) menu.

Customize views

For each dive mode, you can create up to four custom views. For each view, there are two areas of view customization: style and content.

The style of the mode can be prominent, graphical or classic.

Prominent style presents key information with large numbers:

Styles Prominent

Graphical style presents information with additional visual elements:

Styles Graphical

With classic, information is presented in the traditional manner using numbers:

Styles Classic

Within each view of the mode, you can define what information is shown in customizable fields. When editing the view in DM5, you get a preview of how it will look on your Suunto EON Steel.

In each view, you can define multiple custom field pairs for the values shown in the lower left and right corners. When you use the view in Suunto EON Steel, you can cycle through these field pairs by pushing the lower button.
