Summary: hi all I shall begin this review by saying the item pretty much does what it's supposed to do the screen is a good size and the 1:50 map of the UK seems to be of good quality. After using it for a short while I soon learned most of its features. Although I've yet to use it in anger out in the wilds.
Summary: This product is a huge advance on the Garmin Edge 605 that I had before. It has a much bigger screen and displays an OS 50,000 map that is exactly the same as the paper version. I use it off road on a mountain bike and it is just about impossible to get lost. Battery life is excellent.
Summary: I brought a SatMap last autumn, and as a regular hiker, thought it would be perfect for winter walking, where you really don't want to be fiddling with paper maps. Overall it is a great product, the 'you are here' circle is brilliant, and the screen is large and clear.
