The term 'Orienteering Device' can be summarized as a COMPASS, which is a seven-letter word. A COMPASS is a navigational instrument used to determine direction relative to the Earth's magnetic poles. It consists of a magnetized needle that aligns itself with the Earth's magnetic field and points towards the north. Compasses are used by orienteers to navigate through unfamiliar terrain, allowing them to find their way from one point to another.
