In case you didn't get a manual with it

I picked up one of those off ebay a few months back and was worried about the same thing. Then I realised that it NEVER gets as cold here as it does over your way, so the compass is unlikely to develop a bubble while I'm using it unless I go mountaineering in NZ.

The MOD must be clearing out all their old stores of those compasses - absolute bargain. The tritium on mine still glows.

Useful tip for all us compass users, thanks

I don't trust compasses any more... ideally I would have 3 brand new ones on me and triangulate the readings..

When I use them it's mostly to get a general -that-wayish-sort-of direction over short distances. F.eks in dense spruce forest. Else I just look at where I am...(on an island, so if I can see the sea, I know where I am :-)

I think they can develop a bubble at high altitude too. But I do mean high.

Check out (if you haven't already) Crawlingroad's Utube channel, some good vids on there.
