-==== The target finder ==== 
  
-The "​**''​target finder''​**"​ {{:​icon_04.png?​nolink}} is a graphical representation of the direction toward the targeted waypoint. Once the green arrow is at the center of the target finder, you are currently looking at direction of the target.+==== Target and navigation ====
  
-{{:​icon_help.png?​nolink}} The application uses the screen center ​location as your current location. You can lock this screen center point on the current GPS location to get updated directions, based on your real location.+When a location ​is set as target, the compass view can be used as a navigation tool, and the following information is given:
  
-It also gives you the following information+  * The **name** {{:icon_01.png?​nolink}} of the target, if any; 
-  * **The bearing** {{:icon_05.png?​nolink}} of the target, in degree, which is the angle between the geographic north and the targeted waypoint, at your current location; +  * The **direction** {{:​icon_02.png?​nolink}} of the target, from your current location, pointed by a green arrow; 
-  * **The direction** {{:​icon_06.png?​nolink}} of the target, in degree, which is the angle between your current ​heading and the bearing of the target, at your current location; +  ​* The **absolute ​bearing** {{:icon_03.png?​nolink}} of the target, which is the angle between the geographic north and the target, at your current location;

 + 
 +{{:​icon_help.png?​nolink}} All these figures are computed from the map center location. Be sure that it's correctly located on your current location, either by moving the map manually or by locking the GPS location on it.

 +When you move towards one direction, be sure to orientate your device correctly so that the **lubber line** {{:​icon_05.png?​nolink}} matches your forward direction. In this case: 
 +  * The azimuth value displayed under the lubber line is your **heading** {{:icon_06.png?​nolink}};​ 
 +  * The **relative bearing** {{:icon_07.png?​nolink}} of the target ​is displayed, which is the angle between your heading and the bearing of the target, at your current location.
