compass and equator
i'm riding with a mate to namibia this summer and we're taking a gps. i want to take a compass as a backup. but i'ff always heard storries that when you cross the equator with a compas mend for use in the northen heminisfere that when comming close to or crosing the equator is will become stuck because the needle will "lift" its point and will try to point trough the glass. i understand the idea and it sounds plausible but does this actually happen? or is this just a tall tall. since there are "world compassas" avalible with should not have this problem it sounds plausible but then again, companies will try to have us believe any thing if they think they can make a extra buck. so do i need to buy a expensive "world" type compas or is my old dutch recta good enough?
