What type of compass should I use for walking in the UK hills?

A clear baseplate compass is the usual choice for hillwalking because its edge and orienting lines can be used directly on a map. Other compass types can work, but are generally less convenient for this job.

How do I allow for magnetic variation in Britain?

Check the current information in your Ordnance Survey map legend and follow its instruction for converting between grid and magnetic bearings. Do not rely on an old rhyme, because the value and direction change over time and by location.

Can my phone affect a magnetic compass?

Yes. Magnets in phones, cases and other equipment can distort a nearby compass needle. Keep the compass away from phones, poles, fences and other metal, then repeat and cross-check any suspicious reading.
