AOR Flashlights Camping 8 in 1 Multi-Tool with Signal Mirror/Survival Rope/Magnifying Glass/Whistle/Compass/Thermometer/LED Fire Magnifier/Lanyard/Light
Great kit for camping or emergencies. Don't be caught in the wilderness without one! Cleverly designed and very functional for many purposes. It comes apart with a twist of the easy to see locking mechanism which is a push together and twist about a 1/4 turn, and the same for the magnifier. The needle is very sensitive and if the needle is not in balance, all you have to do is tap the side of the casing to get the needle to move.
