Orienteering Compass 1.0


Category: Navigation
Price: $1.99 (iTunes)

Description:

THIS APPLICATION WILL ONLY WORK ON AN iPHONE 3GS! Installing this application on earlier iPhones will be useless.

Not just a Compass, an Orienteering Compass designed for use while Orienteering with a paper map (maps not included**).

To use for Orienteering:

1. Place the iPhone on a map with either long edge along the desired course.
2. Place two fingers on the Compass dial, this will put the compass in 'set' mode. Six lines will appear in parallel to the Northern direction of the compass dial.
3. Rotate the Compass dial using two fingers. Both the Compass dial and north pointing lines will rotate together.
4. Continue rotating the dial until the north lines are parallel to the northern direction indication on the map, then remove both fingers. The compass is now set to the desired heading.
5. To travel in the set heading, hold the iPhone out in front of your body, and rotate until the red end of the compass needle lines up with the hollow arrow inside the compass dial.
6. When the red end of the compass needle is aligned inside the hollow arrow, the heading display will turn green and two green arrows will point in the direction to travel.

Orienteering Compass can be set for magnetic or true north. When set to true north, the compass needle will not be displayed if the iPhone hardware cannot determine true north. Moving the iPhone in a vertical and horizontal circular motion will aid in calibration of its internal magnetometer, and improve true north calculation performance.
