A guidance device (101) determines direction, and indicates with a discrete transition indicator (104, 106, 108) when the guidance device axis is aligned that direction. This is accomplished through the integration of a radio navigation receiver, in this case a GPS receiver (203) and a flux-gate compass (205) in a hand held unit with a user interface including a keypad (110), a direction display (119) and a configurable display (115). |
