Review on Dependable Boy Scout Compass for Navigation, Orienteering, and Survival - Liquid Filled, Rotating Bezel, Magnetic Heading - Reliable Outdoor Gear by Ricky Gilbert

Declination is when you set your compass to magnetic north. You need to be able to set this to get accurate readings when navigating a topographic map. I did my best to try to adjust the internal dial to set the declination, but I couldn't. It has all the markings needed for declination, but it just can't be adjusted. To be fair, it doesn't list the adjustable declination as a function (although it does have all the declination-related markings). All other features of this compass worked fine but I bought it for a purpose and it doesn't suit me. If you want to give this to someone just to have a compass instead of using it to navigate a map, this makes a good gift. If the person who received these expects to navigate topographical maps, they will throw them away or return them.
