Fundamentals of Orienteering – Parts of the Lensatic Compass

 

Today’s post is about the Lensatic compass.  This is a military style Cammenga compass and I lay out some of the parts below.  If you click on the image you should get a larger picture to look at.

There’s also a short video below that points out the various parts just to make sure you can see everything.

I’m taking this course in little bites for two reasons.  First, it gives me time to prepare the next section and second, it gives you time to assimilate the information before moving on to the next segment.  Don’t worry, it’ll get more interesting soon.  For now we need to learn the tools of the trade before we get to the good stuff.

    I love simplicity & am glad you are breaking it down into bite size pieces like this video.

    When I watched Saving Private Ryan, I remembered the part where Tom Hanks’s character was reading the map & he was using one of those compasses & it really intrigued me how it worked.

    Thanks for taking the time to show me/us this process.

      Glad to help out. I remember the scene in the movie you’re talking about too, I think. Doesn’t his hand shake while he’s holding it?

        Yes, his hand was shaking & it was the first time his troops saw his imperfection. A pivotal point in that relationship because it brought them all closer together.

    I’m also looking forward to learning more about them. I’m pretty limited to where I get to roam and know the place like the back of my hand. There have been a few occasions where I end up in a place I wasn’t planning to be lol, so learning about this would be wise.

    Thanks Jarhead.

    I use the suunto mc-2. I still believe the most danerous man in the world is a second LT with a map and compass!

      Agreed! I’ve got several stories about boot looies with a compass.

    as an ex-Infantryman I feel one can never get enough practice of “map and compass” or orienteering. I also taught this for quite a few years and still keep boneing up on it to stay in practice. Great work! -EvS

      I’ve got to admit that I’m getting a lot of presenting this series. I used to very good with a compass, but haven’t really done any hard compass work lately. This is a great refresher for me too.

    I actually have a compass like this sitting on a shelf next to me. Unfortunately, I have never taken the time to learn anything about it. Thanks for making some tutorials.

      You should take it down and take it out for a spin! Hopefully this will help you learn how to use it. They’re an excellent resource.

    Quick question Jarhead – I went onto Amazon & saw this compass & was wondering if it is relatively the same as yours.

      Sorry for the incomplete sentence …. I started to say, I noticed that some come with tritium & was going to ask what that was but figured out.
