Then when that fails: Sun rises in the east and sets in the west. And as a last resort. Find a stream of water and follow it downhill as it is bound to come to some town as that was how they were usually founded. ie. near water.
I also know how to use a map and compass. How may people do you see with a compass mounted on their Bike?
However a GPS can do alot more than point to Magnetic North and take sightings, and is not effected by magnetic interference.
As in my previous post, I use it to log (and review at home) hills speeds etc. Whilst riding it can give me an idea of the road ahead (relevant maps installed), and a rough idea of how far to, say the lunch stop.
All in one nice handle bar mounted waterproof case.
Yes, I know there are limitations such as limited satellite coverage in mountains, under tree cover (especially wet) and limited battery life depending on the unit.
