Review on Portable Metal Survival Compass Keychain: DETUCK For Hiking, Camping & Outdoors by Jeff Gopala

Awesome compass! It's accurate, and doesn't need to be calibrated like a lot of compasses. However, like just about any compass, it doesn't work properly if it's near any electronics such as the gauges and computer screen in any modern vehicle's dash. I got one to use in my 3-year old Honda because it doesn't have a compass, and as expected it loses accuracy on or near the dash. But if I hold the compass about 18 inches or more from the dash, it works fine. Also it's great quality and the perfect size (IMO). I got a second one after trying out my first one, just to have in case I lose the first one or if it somehow breaks or starts leaking.
