Suunto Nautic S User Guide

Dive settings

For Dive settings, scroll down from the pre-dive screen.

GPS

To track the start and end point of your dive and to get a more accurate dive route, you need to enable GPS in the Dive settings. Make sure the GPS arrow icon turns green in the pre-dive screen before starting your dive to get an accurate location. Suunto recommends you always start your dive from the pre-dive screen.

Dive route

You can track your dive route with Suunto Nautic S. The underwater route tracking is based on GPS, accelerometer, gyroscope, magnetometer and pressure sensor. The algorithm has been developed by using large amount of data from real dives, data analytics and machine learning.

To track your underwater route while diving, you need to enable both the GPS and the Dive route settings. The dive route is not visible in your dive computer. It will be synced to your dive log in Suunto app when connected to your mobile phone.

Note that the dive route signal can be compromised in the following situations: overhead environments like caves or wrecks, indoor pools or with poor on nonexistent GPS signal.

Dive start depth

Set the depth threshold for starting and ending a dive. The default depth is 1.2 m (4 ft) and the maximum is 3.0 m (9.8 ft).

Dive end time

Once you are shallower than the set start depth for the dive, Suunto Nautic S will start calculating the elapsed time at the surface. You can set your desired time under Dive end time. Once this time has elapsed, your dive ends automatically. If you continue diving before the set end time, the dive continues. You can define the time between 1 and 10 min. The default setting is 5 min.

Water type

Select the water type you are diving in. You can choose fresh water, salt water, or for default standardized depth measurement, the EN13319 option.

Brightness

The brightness setting determines the overall intensity of display brightness during dive activities: Low, Medium (default) or High (default). The brightness setting is specific to the dive mode, and does not affect other dive modes, outdoor modes or the general brightness setting.

To save battery life during dive activities, the display brightness will lower after a period of inactivity. Any wrist movement, button press, or alarm trigger the full brightness mode. You can also adjust the brightness during dive by long pressing the upper button.

Feeling

If you are training regularly, following how you feel after each session is an important indicator of your overall physical condition. A coach or personal trainer can also use your feeling trend to track your progress over time.

There are five degrees of feeling to choose from:

• Poor
• Average
• Good
• Very good
• Excellent

What these options mean exactly are up to you (and your coach) to decide. The important thing is that you use them consistently.

For each training session, you can record how you felt in the watch directly after stopping the recording by answering the 'How was it?' question.

You can skip answering the question by pressing the middle button.

Resetting tissues

You have the possibility to reset tissue compartments, that is, to clear the data regarding the residual nitrogen after a dive. After tissue reset, the previous dives have no effects on the dive algorithm calculations.

To reset tissues, go to Dive settings » Reset tissues.
