Calibrating compass

When you first start using Suunto D6i, the compass needs to be calibrated. Suunto D6i displays the calibration icon when you enter the compass.

Calibrate the compass by slowly rotating the unit in your hand in large figure-8 loops..

During the calibration process, the compass adjusts itself to the surrounding magnetic field.

If the calibration fails,Try Again appears. If calibration continues to fail, move to another location and try again.

When traveling overseas, it is recommended that you recalibrate the compass at the new location before using it.

To manually start the calibration:

  1. While in the compass view, keep DOWN pressed.
  2. Press DOWN to scroll to Calibration.
  3. Press SELECT to start the calibration.

Setting declination

You should always adjust your compass declination for the area where you are diving to get accurate heading readings. Check the local declination from a trusted source and set the value in Suunto D6i.

  1. While in the compass view, keep DOWN pressed.
  2. Press DOWN to scroll to Declination and press SELECT.
  3. Press DOWN to toggle to East or West and confirm with SELECT.
  4. Set Declination Degrees with DOWN or UP.
  5. Press MODE to save and exit.

Setting compass timeout

You can define how long the compass stays on after you have activated it. Reset the timeout with any button press while using the compass.

After the timeout, the Suunto D6i returns to time or dive mode.

To set the timeout:

  1. While in the compass display, keep DOWN pressed.
  2. Press DOWN to scroll to Timeout and press SELECT.
  3. Adjust the timeout time with DOWN or UP.
  4. Press MODE to exit.

Setting bearing lock

A bearing is the angle between north and your target. In simple terms, it is the direction you want to travel. Your heading, on the other hand, is your actual direction of travel.

The default bearing is North.

You can set a bearing lock to help you orientate yourself underwater and ensure you maintain your direction of travel. For example, you can set a bearing lock for the direction to a reef before leaving the boat.

The last locked bearing is stored and available the next time the compass is activated. In Dive mode, the locked bearings are also stored in the log. To lock a bearing:

  1. With the compass active, hold the watch in front of you and turn yourself towards your target.
  2. Press SELECT to lock the current degree displayed on the watch as your bearing.
  3. Press SELECT to clear the lock.
