Title: Better compasses out there....
Review: This compass doesn't have an on / off switch but appears to switch off when not in use. I suspect mine has a fault as it keeps losing it's calibration.At the end of the day, this is a budget compass and I certainly wouldn't rely on it for orienteering or anything life saving!
