    this compass has been through many adventures and adventure races with me. it's great and always works. however if you have to change the declination frequently the little screw will get stripped. i have used it for years but i can no longer change the declination on mine. that sucks, but i think it's common.

    the ad for The Suunto MCA-D Challenger Compass says it has a fixed declination scale.

    Just what does that mean? Does it have a declination adjustment or not?

    I just got this compass for my Dad (Father's Day) and the answer is no, this compass doesn't have an adjustable declination scale. The declination is fixed on the scale, doesn't move, so you just have to subtract or add the declination that you read on the map from your measurements. Personally I'd recommend the Silva Ranger compass or another with adjustable declination.
