I've been using Anquet for a few years now and there is so much more you can do with it.
You can set it on an area and print it out either at 25,000 or 50,000 scale, you obviously get more area at 50,000

Even if you only have the 50,000 scale map.
Load tracks straight from a hand held GPS into it and see where you have been, how far, height, ascent and or descent.
Mark out a track and see what it looks like and how far it is, set up Naismith Rule to your own pace and estimate how long it will take, then upload it to the GPS and follow it when you get there.
Change the map to Virtual Landscape and see all the ups and downs or Split Screen to see map and landscape together.
I laminate the map for the area I am going to and use that rather than the OS map which I keep tucked away in the rucksack. All the grid lines are there so you can still navigate with the map and compass.
I am now considering whether to upgrade to the new version from the 1.2.20 version I have at the moment as I believe the saved information from this isn't compatible and I can't be bothered with all the hassle of converting them
