That's a reassuring page. I sent an e-mail and we'll see.

A compass, like my matches, is something I don't like to muck about with - or tolerate defects. I've been in situations, in the real world, where my life did depend on proper functioning of this bit of technology. While I normally carry two capable compasses on serious trips in the wild (and own several good ones e.g. Cammenga, Suunto, Brunton), I like the old Ranger and want to keep it ticking along.

Thanks for all the help from the forum.
