Went out yesterday with a GPX route loaded into Outdoors GB. Worked a treat. 1:50 is okay if you know at least some of the area, but 1:25 obviously makes it much more easier and reliable.
Certainly encouraged me to check out some stuff I’ve never thought of before, not least because I’d always be able to find my way to the next section without faffing over a map.
Device (in recording mode) used 50% battery in 2 hrs 30 mins. Not great, but not bad.
But it’s intuitive, route can be switched on/off, panning and zooming is allowed, plus it’s accurate.
So I’ll probably download a couple of 1:25 county maps (£50-60) and crack on.
