Review on Sportneer Military Lensatic Sighting Compass With Carry Bag - Waterproof Boy Scout Compass For Hiking, Camping, Hunting Outdoor Survival Tactical Backpacking Compact Handheld Navigation. by Maurice Stavros

I bought this compass because the magnetometer/compass in my phone is terrible and always gives incorrect readings. This is an ordinary magnetic/mechanical compass. It has the usual features, a cover that protects it and when raised gives you an aiming line and a few notches that can be used to find object sizes if you know its distance, or distance if you know its size - not a direct read, some mathematical work required for this, the numbers table included in the manual, can be copied into your phone. There is also a bearing bezel. A little lens magnifies bearings for a more accurate reading. The manual says this little lens can be focused, but I did not find that to be true. For me, the lens works fine without my glasses on but is useless with them. Still, there is little point to this feature unless the compass is held steady and level on a table or tripod. Hand-held (because of wobble and tilt) the lens is no more accurate than merely looking down on the top of the compass disk. The manual also mentions a vertical angle measurement feature, but that is not available on this model.The metallic case is solid and protective. The glass cover is also protected, and the nylon case is fine. Overall a decent tool for the money.
