Suunto DX includes a digital compass.
The tilt-compensated compass gives you accurate readings even if the compass is not horizontally level.
The compass can be activated from either time or dive mode and shows the current bearing and depth.
When in dive mode, the compass display includes additional information in the bottom left and right views.
When you first start using Suunto DX, the compass needs to be calibrated. Suunto DX 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:
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 DX.
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 DX returns to time or dive mode.
To set the timeout:
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:
If, at any point, your bearing moves outside the compass display, right or left arrows appear to show turn direction.
Suunto DX provides help for navigating square and triangular patterns, as well as navigating a return heading with the following symbols.
|You are traveling towards the locked bearing.|
|You are 90 (or 270) degrees from the locked bearing.|
|You are 180 degrees from the locked bearing.|
|You are 120 (or 240) degrees from the locked bearing.|
