My current Silva compass has developed a large air bubble which I am sure must affect the accuracy of the reading - it certainly undermines confidence in it.

I was shown a Silva Jet 5 recently, and was well impressed by the smooth action and damped movements of the needle and wondered if anyone can give feedback on their use, longevity, similar alternatives, etc. The going rate on't th'interweb seems to be about £60, so any comments good or bad would be appreciated.

Cheers
