    Re: Accuracy of backpacking compass

    I agree with you, very accurate compass to use. The compass card is accurate and the sighting system allows accurate reading. I have taught many classes in land navigation in the army and I would give it one degree or at worse two degree accuracy.

    I also use the hockey puck when sailing, I wear it around my neck and tell people that it is my "magic amulet" that keeps rocks out of the bilge. Same level of accuracy and is even easier to read than the army lensatic.

    Also in the field artillery we use the M2 compass which is even more accurate but is more difficult to use. The M2 is marked every 10 mils which is about 1/2 degree and we use this level of accuracy to aim the cannons to hit targets 20 miles away. You can buy the civilian version of this compass, it is the Brunton pocket transit, but they are not cheap.

    Brunton also makes the lensatic type.

    And if you want to have a control compass to compare the readings of your students with their compasses, get a pair of binoculars with a built in compass like the Fujinon, reasonably priced and about one degree accuracy.

    I use the U.S. Army 'Lensatic Compass' made by Cammenga for backpacking. It is a compact compass that is great for taking azimuths. The Army teaches their young officers land navigation using this compass. It has a luminous bezel indicator, induction damping for fast azimuth acquisition, and a sighting system to get more accurate readings.

    The key with this type of compass is that you need to learn how to use it properly. Proper instructional material is available on the web at no cost.

    There are some cheap knock-offs on the market, so if you like this type of compass, be sure to get the one made by Cammenga.
