GPS Navigation

Using a Garmin Etrex GPS

GPS devices are becoming increasingly popular as a navigational aid in Scotland. GPS stands for Global Positioning System, and these handheld devices calculate your position by reference to a series of satellites orbitting the earth.

Much has been written about GPS devices, and many walkers have been critical of them. We feel much of this criticism has been made because many people are worried that walkers will not bother learning proper, traditional navigation using a map and compass and will rely solely on their GPS. It is true that using a GPS device does not mean you shouldn't be carrying a compass (what if the batteries run out or the device stops working?), still less that you wouldn't need a map, which is essential for all but the shortest, waymarked walks. Despite this, GPS has a huge amount to offer those with the patience to get the most out of it - see Using your GPS.

For software, we reckon you should take a look at Quo. This program - the basic version of which can be downloaded free from the link above - enables you to plan routes on your computer. You can purchase and download Ordnance Survey maps through Quo, at both 1:25 000 or 1:50 000 - from just 99p per 40km square. You can then view our Walkhighlands routes on the maps (if you buy the PRO version), or draw your own routes. See the Quo page for full details.

But which GPS device to use? Well, take a look at our GPS shop. The Gecko devices are the lightest on the market, but the AAA batteries don't last as long as the AA batteries in the Etrex. It's worth going for the newer 'H' model as the receiver is more sensitive when the sky is obscured by cliffs or trees. It is possible to buy devices that can show a 'Topo map' with contours on the screen, but we feel that the basic Etrex does what most walkers would need. Check the prices in the GPS shop.
