GPS

I've just bought a basic GPS locator and have been trying it out in the park; it's very simple to use, even with one gloved hand - the hardest thing was attaching the lanyard before I set off. The unit, apart from being able to locate my exact position, accurate to thirteen feet; also has a multifunction trip odometer, an altimeter function (that I suspect might not be particularly accurate though) a compass, and various functions more suited to orienteering or geocaching.

Because I usually hike alone on the moors, above all it will give me piece of mind...but I'll still have fun with the trip statistics when I get home.
