I was out activating GM/NS-025 Beinn Enaiglair - 889m a couple of weeks ago. True winter conditions, snowing on the summit with poor visibility. Got the summit activated, now to navigating off… The compass said we should go in the opposite direction to where intuition said we should go… Moira, said I should check the GPS. I said compasses never lie and you must trust it even if it seems wrong, this has worked for me many times in the past… I got the GPS out and it said the compass was 180 degrees out… comfirmed with Moiras compass. My compass had been sitting in the top pocket of my rucksack with my Blackberry molile phone in it’s magnetic case. The compass had been re-polarised 180deg out! Have often had phone and compass in the same pocket. Never had a problem before. Will never keep them in the same pocket again!!!
So I thought I should warn you all of this possibility. SILVA have kindly repolarised my compass and said this can happen with mobile phones of any make and and GPS’s.
If Moira had not been on the ball we could have walked off the wrong side of the hill in poor visibility into who knows what, we were expecting an easy slope, we may have happened on a cliff. When you have been playing radio on the summit you can get disorientated and may not realsie there is a problem. So from now on mobiles and GPS units will be in a different pocket to the compass!
Has anyone else experienced this problem?
