Ahhhh thank you, found one of these military looking compass but never knew how to read it. Now it's more clear.

I was super confused the whole video until you got to the part with the 10.5 degree azimuth conversion, then it all clicked finally. I feel pretty cocky now, like I have a super power lol. The Army still teaches this, not because they dont issue gps devices but because you have to be prepared if they fail. I failed this when i went through basic in 95 and never learned it. Thank you!

Practical proof that the lensatic compass works perfectly fine with a map, unlike what many people think, or they are eager to sell mirrors to the crowd... excellent video.

This video made me love my Cammenga compass even more! Not having to bring my protractor is a big improvement and makes it as easy to use as a baseplate compass. I think people are worrying too much about the three degree clicks. Most navigation is done using rough directions and backstops. Only when doing dead reckoning is the accuracy so important. Most compasses are only rated to be within 2 degrees anyway.

This is a helpful thing which school doesn't teach us.

Holy shit! I was taking all kinds of fire of the SF recruiting BN video of land nav at Mackall. I was trying to teach this and all these guys were talking shit. Glad someone else knows it, thanks alot!

Great technique! After doing these adjustments that you demonstrated, all i had to do was to point the magnetic arrow towards the luminous light and voila! Its oriented to my direction of travel.

Would have been really, really nice if Cammenga made their compasses with a transparent bottom and given it rotating alignment lines, just like a baseplate compass. And if instead of the clicking bezel they would have went for a friction one... it would have been the absolute perfect compass.

This is such a huge help to not have to always fight with the protractor issues. Can we get a video for how to plot points TOO!! Thank you!!

Thats a great, clear description of a really simple way to remember. On a side note. I recently updated a few of my 25 yr old topo maps for my local area here in Australia My old maps, as yours there have perfectly lat and long lines. My new maps, the lines ara a pale blue and sooo faint, even with mglasses on, and under bright table lamp , they are almost invisible. They are disgraceful. A second thing on the new map...no declination diagram. K ust written, ," Mag north ís approx 13.04° East of grid North. I just spent an hour inking the grid lines on a brand new map.A Romer card would be impossible to use without the re inking So hard to find who to send some bad feedback to about it. Anyway, Great video mate 👍🇦🇺 Cheers from Oz Neil

thanks for the explanation. It is very useful because it gives you azimuth without first having to orient the map. In practice, the Cammenga can be used as a Siva or Suunto type chart compass.

This is such an important video! I prefer ruggedness over convenience but I was taught with silva compasses and got those because of the ease of working with a map and not needing a protracter. Thank you!

That was clear and concise, excellent Video! Thank you

I'll Always Love you Hayden Panettiere for Time and All " Eternity."

Really love this! Thanks!

Really easy and understandable 👌👍

With i knew your name. You are very talented!😀 Super job!

Exactly how I learned for baseplate compass.

Also, if you site something in the distance, like a target. You snap the bezel ring down, it will lock the dial. Then just put the arrow straight north and the 0 on the scale on your position. Whatever you estimate the distance just plot that along the distance scale.

Great video! Thank you. 🙂

Great info, thanks for sharing!

This is a fantastic video displaying a practical technique using a lensatic compass. You provide a easy to understand video when determining grid azimuth. I would add a minor thought. When adjusting for declination. If like this example, you fall between either 3 click or 4 and being overshooting by 1 1/2°- just now do this part old school math. Just subtract the declination from the grid azimuth. Then you get the exact adjusted magnetic azimuth. Also good idea to draw a longer line between the two points on your map, now you can slide your compass along the line to get a better visual of your bezel line a matching the map grid lid to aid in lining up the two lines. Excellent excellent video👍 Cheers

I have a small military protractor in my nav kit. As a backup, I carry a flexible half-moon school protractor in my nav kit. Perhaps you can do a video on plotting with a half-moon protractor. I enjoy your videos. Well done.

Pretty slick, I learned how to do this with having the map oriented to mag north prior to using the straight edge but I see how this could be even quicker.

Very good! Thank you.

Thank you, very informative....

If you orient the map first to magnetic north, you can then measure right from point to point. You'll only need to spin the dial once.

Fantastic thanks

I'm new to this land nav stuff. Curious on a good compass, I have been looking and not sure what is too cheap and what is too expensive. Thanks if you get to this. Great video.

You did a good job of breaking this down. It this just proves to me I'm incapable of learning how to use a compass after trying for more hours than I care to admit. Frustrating as shit.

Nice video, man. Thanks for sharing. I guess, basically, you are using that tritium marker like the meridian lines on a baseplate compass? In that case, does it matter if the map is orientated North to obtain correct bearings, so long as the tritium marker is pointing North and aligned with the grid lines? It seems to me that I could have the map facing in any direction to find my correct compass bearing. I picked up a kit of ESSE 'survival' cards and it came with a few business/wallet size map scale cards...and one of them I believe is called a compass rose. It is simply a 360 degree compass dial (thin, flexible transparent plastic card), with a center hole provided for a string. Line up the edge of the card with a grid line, extend the string out tightly in a straight line reaching from starting position to destination and that is the correct bearing/azimuth (East or West declination to be added or subtracted to GN of course). Is this correct? For naval navigation there are several compass roses provided on your navigation charts (aviation charts as well), and those charts/maps do not need to be oriented because the compass roses are already aligned for North with the map. You take all compass bearings from the stationary compass rose, and not moving a compass over the map/chart. I hope this makes some sense! If it does, get back to me to confirm I am correct or incorrect. Cheers!!

Thank you for this video of finding the azimuths with a Lensatic Compass. I want to point out what I noticed because I think I missed understood or missed on something before my question: At about timed 04:40 you confirmed your grid azimuth when you lined the luminous line with the magnetic arrow at 300 Degrees. Then you moved the bezel ring clockwise to get 286 Degrees. But at about timed 08:55, you took the the compass next to the Declination Diagram without having the luminous line and magnetic arrow lined up. Your compass read at about 130 Degrees if I read that correctly. I see that your map is 10.5 on your Declination Diagram. Then the diagram says to Subtract when converting Grid Azimuth to Magnetic Azimuth. When and how many times I rotate my bezel ring on a compass if I'm either holding it on and off my map? Would I be wrong if I Subtracted the degrees?

Excellent! 😉😁😁

A simple rhyme to remember as used to be taught in the UK military in my time: from mag to grid get rid (-) from grid to mag you add (+), that way you wont be adding or subtracting the value of the magnetic deviation from grid north the wrong way around, for calculating the back-bearing there is no need to flip the compass around just subtract or add half of the scale, if in mils that would be 3200 and degrees that would be 180, I must confess I have not had to use a compass in anger for 40 years tho :/

Sweet!

Thanks

Thanks!

Kickass

Yo man, I just posted your video on the special operations recruiting battalion short video on sfas land navigation. I hope you get more traffic

Thank you. I love an old school compass...I was given one of these by my son. Love it! How do we use the magnifying glass? Is it simply toenlarge detail on your map? It looks like it should be some line of sight.... thing!

Great info.Thanks.

Thank you. Very helpful.

1.5⁰ difference seems like a lot if traveling further. when you over/undercompensate degree adjustments, would you just slightly change course at intervals to stay on track?

really well explained, English isn't my nativate language but I've got it despite the fact I didn't in my mother tongue

Could you have just oriented to 289 instead since it's the more accurate direction of travel?

Learned the same technque in geology course

Would you be able to do this hack while converting from magnetic azimuths to grid azimuths? Or in other words, while performing intersections and resections? If so would you make a video to show it?

Nice job I learned a couple of things but in stead of doing the math with the declaration I learned to make the magnetic grid line longer and use the line to orient the map to magnetic north first this was you don’t have to make any math

💞

Sir before you start everything, can you read declination on map adjust it, then proceed, what's the difference to do it after

This is very helpful! Question: it looks like the short glowing line doesn't match up with the glowing line on the north-seeking arrow. How do you compensate for that? Or is that just the camera angle?

Thank you so much for this simple explanation! But I do have one question...do you have to be actually on site to take a proper map bearing with a Lensatic Compass? I am practicing plotting bearings (at home) using a map & compass, and checking my numbers with Google Earth; but my numbers are off :( Even when I account for declination. Not sure what I am, or not, doing correctly. Going from a transparent baseplate (with alignment lines) to a floating dial with degrees, is a learning curve for me apparently.

AND they say you need a protracted to do this when using a Cammenga Lensatic. Ha! Thank you!

It does work great if you have a 50k map. However I’ve never used anything for EIB or land nav other than 25k maps. Never understood why the compass isn’t marked on both sides.

regardless of what side the mag North is on the GM angle, don't you still use the classic formula like it says next to the GM angle map "To convert a grid azimuth to mag N ADD GM angle?" and subtract for Mag to grid? Even if in your region of the map shows Mag N left of the GM angle Grid North going from Grid to North you would still add? Turn bezel right?

I have a little problem. I didn't understand if you oriented the map towards the north before taking the measurement

Why do you have to turn the compass to get north lined up with the luminous navigation line? 4:24

So it doesn't matter if you have a 1:50k or a 24k or a 62k map, they all are 1000 meter grid lines right, so I can use my milliary protractor 25k scale and get perfect distance and azimuth . I'm I correct in that assumption?

Sir, the lensatic compass used here has graduations of 5 degrees(least count)...how do you set bearing that are not 5 degree multiples...for example say i want to travel at a bearing of 242 degrees using this compass and navigate the terrain?...would an approximation induce error?...thanks

Sir, do you orient the map before you do this?

where do you get those maps?

If I were to look for maps that I can use with one, what are they called?

Oh my lord. Just get a base plate compass and save yourself lots of grief. Update: After taking more time to get into their idiosyncrasies, lensatic compass are every bit as good. Base plate compasses do the heavy lifting for you with declanation conversions but you get the same results with a lensatic with a little brain power added.

This is an argument I'd like flat earth peope to explain ... How does a compass work if the world is flat??

Comment

So this type of compass is always off a 2 to 3 degrees 🤣

elevation 547, over

You just lost A few students of mine with your video. Lol. I backed it up,and reviewed while watching myself and realized I have a better method of less confusion. So at this point I am highjacking todays video hour and giving the declination class myself minus the video.

💀☻️⛑️🌛🧭🌐⏳️SIMPER🤏🏿💢👍🏿FI°⌛️🌐🕰🌜🪖🌚👽

always always Orient the map first ! ... or forever be lost .

300° subtract 10.5° will give you grid to magnetic 289° , simple math rather than using clicks.

Poor explanation for someone trying to learn

Thanks
