We all know that if you put a battery close to a compass it will affect the compass needle. Because of this, or because of something I may have read in the past - I have always been paranoid about storing my compasses near anything metallic or magnetic, or batteries in case it permanently affects the accuracy of the compass.
For example: I have never carryied my silva in the same rucksack pocket as my headtorch. I never feel happy to pack a survival kit with compass and batteries for the same reason.
Does anyone else do the same?
Does anyone know if there is any substance to this fear or should I not worry and pack em how I like??
