USMC Land Navigation Sergeants Course is sold on Amazon. The two compasses you highlighted are the only two I would trust my life with. For anyone wanting to get out and learn, they can find a local orienteiring group. REI may even offer classes.
I know it's been 4 years but I have a question what is model of protrek casio you have?
Thank you
Only suggestion I’d have is remember to adjust your bearing to include magnetic declination.
Always impressed at creators who make their content with Mr. Tripod. He is a highly decorated, award winning film maker with the most Academy Award nominations ever. No clue how this guy afforded Mr. Tripod as he usually demands millions in both budget and huge percentages of box office sales. Very impressed.
Yup. Thought the same thing
Thanks, finally a lesson on reading a compass that i could understand.
I'mglad it helped
Me too. Civvie here. Helped a lot. Hopefully i wont be lost in the triple canopy jungles of the Philippines. 😬
I still have mine that was issued to me while in the Marines way back in 1988. I qualified with this
Compass... At night!!! I'm in my 50's now & still prefer to navigate with this Compass than a GPS.
Thanks for highlighting this amazing piece of tech.
Cool
Semper Fi
This was great. I’ve been through a couple land nav courses in the military and this easily made things a lot less complicated than it’s made out to be. Thank you.
Looked good to me, good to know it meets military approval (That's you ;) ) . Couple of us heading into desert, just wanted to get brushed up, for the first time and not get too parched.
Thank you for the refresher course.
Haven't done this since I got out of the military about 45 years ago.
You are welcome
This is definitely one of better presentations on Lensatic Compasses .Thank you Sir.
Glad it was helpful!
Nice. Technic tip: you can hold your eye to the little magnifying glass, and see your bearing and see the wire (direction) at the same time. You don't need to lift your eye to see the wire.
Slide the lensatic eye piece into the cover that has the grove to match the lensatic grove. They should be touching.
thx! I think if I had graduated lenses like the OP, I wouldn't be able to do this, but you pointed it out!
I have tried to understand how to use one of those, but maybe my mind wouldn't catch ahold of what the instructor was saying, but I think now maybe a little of me and instructor,
But Brian, it was very clear to me how you explained it!
Thanks for ALL your videos, they help so much!
Side note, I'm 70 now and joined the BSA when I was about 10 and only stayed about 2 years then quit, maybe me maybe scout master but something didn't work, but if he was anything like you, I would have been a proud eagle scout and probably a life long scout master like you!
This learning video is worth its weight in gold, just some people have the gift of teaching that comes naturally and he has it, learned very easy and understandable.. TY
Was seriously terrible at this no one ever explained the purpose of the index marker. Lighting just struck my brain. Thank you
Well done Sir. I'm preparing myself for my first moose hunt this coming fall. That's 6 months away but I want to be ready and confident. Thank you.
You know where the best place to shoot a moose is, don’t you?
And you can bet if ANYONE knows anything about compass reading it's a scout!
Great video!!
Great lesson but you alway have to remember to adjust for your Grid Magnetic Angle which moves slightly every year. It only works out to a few Mils but when walking on a bearing for a long distances, it can make a big difference to where you end up. 👍
Where I live magnetic variation is 357mils
It depends on where you are, where I am in the Eastern US, it’s 12 degrees, much more than a few mils. There are places out west that are much more than that, just easterly rather than westerly.
I'm 28 so I'm a little too old for Webelos or whatever, these videos are as close as I will get to being involved in the Scouts again. Please make more videos like these
I’ll try
I would've failed land nav in the Army if not for buddies who were good at it.
This is a great vid- best explanation + DEMONSTRATION I've experienced. Subbed
I am glad it helped. Thanks
I bought this compass year's ago only seen 2 videos that explained it simple n easy thx you great video
Last year I just retired my Cammenga compass that I had when I got out of the Corps in 1983. Bought another Cammenga phosphorescent model 27. But after a while, I missed having the tritium, so I bought a model 3H. Then a week later, I couldn’t resist getting the Cammenga wrist compass with tritium.
Yeah, they’re that good 👍🏻👍🏻
Yes they are
Thank you, thank you, thank you. The first youtube video were I could understand how to use compas.
This was a great video! It gave me an idea as to how to use a compass when I had none. You explained it well.
I'm glad it helped.
Best instructions on how to use the compass by far, simple and to the point.
The top and the bottom touch then you look through the lens. Nice job
Great video. After looking at several compass and pace bead videos I learned the most from yours. This made the Lensmatic seem more intuitive. I may pick one up when the old pension check gets here.
I'm glad it helped
You explained that well in terms even I can understand. Other explanations I've seen of the Cammenga 3H overcomplicate things.
4 years of being in the Army and having this explained differently each time Ive never fully understood. Thank you. You made this so easy!
🤣 Army. Should have joined the Navy. Lol jk we use the stars to direct our sea free floating spirits
Wait. The Army has been lost for 4 years?
Land Navigation instructors in the Army ha ha
Very confusing explanation as far as I am concerned - I still don't understand how to use the army compass.
@@galehess6676 Actually, the Army has been lost for nearly 250 years.
I agree with the commenter below, finally a video on compass reading that I can understand... fire the most part. There are lots of things that others don't seem to cover. For example, why would you need to set a bearing? The reason is because on a map there might be obstacles between you and your objective. I'm using a cheaper compass (Brunton), my compass face has two lines... (What is the second line for?) What happens if you get off your bearing as you travel at night? My guess is that you would have to re-identify your location if you got far enough off track.
Something I would have mentioned is return bearings, and how to be careful not to alter the magnetic properties of the compass. I totally agree with you that everyone should know how to use a compass. Great Video!
I think I covered that in my earlier playlist. If not, I'll get on it ;-)
Cool video! I learned how to use one in basic training when I was 18, I have used one in a while amd needed a refresher thanks!
Glad it was helpful!
That was the best lesson on the compass I've ever seen. Books overcomplicate it. Ty!
Glad it was helpful!
You are a very clear and awesome instructor for this device. I really enjoyed this material. I'm for sure subscribing, have a blessed one
Never good at orienteering even though I was a Scout way back. But dusting of those old brain cells getting back into it. Thanks for the help!
Glad to help
Excellent video thank you! I’ve watch numerous videos trying to explain this topic and yours broke it down in an understandable way!
Glad it was helpful!
Thanks for showing us all these carpisses.
Love it carry one for years all over the world, drawing the strait line is cool and it works ,But protractor is better, Good job.
Whatever works
Great explanation of using this compass. I got the one less expensive version of this compass. But I've wanted a compass for a long time.
Very easy to understand way to read a compass.......Thank You !!!
Thanks
I love the Insight on this video Bryan. Thank you for the tips on how to use a compass I always love expanding my knowledge. And that's why I love your videos. Please keep up the great work. Looking forward to seeing more.
Thanks Dave
As a vet, I was in Field Artillery. In F.A we use mil-radians instead of degree's. 1°= 17.78 mil. 6283 mil in 360°, which when firing a explosive 20 miles or so, the mil factor is absolutely necessary. That's probably the biggest difference between civilian and military compasses. I don't believe some needs such equipment for Hunting or hiking. The military compasses are quite expensive because of the ability to break 360° into mils. Good day too you, thank you for the info. More people need to know map and compass navigation.
Amazing, now I know how to use a compass
You can do a three legged, or triangular, compass walk. Pick a bearing and count your paces. One count for every time right foot (or left) hits ground. Stop and turn the bezel 40 clicks to the left. Walk the same number of paces. Stop and once again, 40 clicks towards the left. You'll wind up at your starting point, or at least very close. You'll walk an equalateral triangle. Each detent on the bezel is 3 degrees. 40 X 3 = 120 which is each angle of an equalateral triangle. You can turn it either way initially. Your direction of travel will be opposite from the direction you turn the bezel. If you turn it toward the right...it'll send you to the left on that leg. Just be consistent in whichever way you rotate the bezel. Check out "Ranger beads" which help keep track of paces. Also, learn what your personal pace count is per 100 meters. Average is about 65. So every time you count to 65 (or whatever) pull down a bead. Great confidence excersise. Try for one kilometer per leg of the triangle. Know beforehand what direction it is to get back just in case.
So is this to fine tune one's precision? Kind of like doing homework, or as AI says, "practice?" In other words, are we talking about practice?
Straight and to the point. As a life long Scout, it was NICE to have a 10 Minute refresher for landmark navigation. Get a pen on that map and you can teach waypoints! But you knew that... Thank you!
I have been terrible with compasses my entire life, but I have always wanted to know how to use them. I just can't make it make sense to me. I am going to watch this video a few more times and see if I get it. Thanks for the video, and all the explanation.
I hope it helps.
Thank you! Great explanation!
What a fantastic video- thanks so much for explaining this. Really easy to understand
Great video, thanks for your time and info. I have been educated.
Me too.. That guy compass for Dummies ( Poor ) Whatever ..Confused me ..
Ok, NOW i understand it. One thing, what you said at the end is a point worth emphasizing, that when you line up the North needle with the yellow bearing marker, you have to keep it there as you walk. If you dont, you wont stay on the bearing and will wind up in timbuktu. Its critical because if you lose sight of some distant target you made at the beginning, like some big rock or something, how would you know you are staying on course towards it?
thank you for this. You explained it better
Glad it was helpful!
Focus, grasshopper.
That snapped me to attention right quick
Also on the lensatic compass with illumination by tritium, the lifespan of tritium I've read to be about 12 years. Then it begins to fade out over time.
Great information I never knew how to use that compass. Question; Do you know what the mirror is for on that other compass? ... ... That is so you can see the one who is lost. 😁😁😁LOL "Da-uppers"
Signal mirror?
Fantastic instructions and guidance video! Really looking forward to applying the knowledge now. Thank you!
Good video on this often misunderstood compass. I’ve always been drawn to the lensatic style compass and owned one like you used in the video.
However, I began noticing that former military (like you, I am not) had some not so complimentary comments about this style. In fact, the hosts of 2 of my favorite TH-cam channels Corporal’s Corner and Gray Bearded Green Beret (both former military) seem to recommend the Suunto compass you also displayed.
It would be interesting to see a comparison of the features of both compasses to help guide us in the best direction.
But, in any event, thank you for this quick and simple explanation.
Myabe next time. Both are excellent compasses
Survival On Purpose 👍
Thank you so much for the information.
No nonsense explanation, thank you.
You're welcome!
Good job sir .finaly other than your strange speach .im from AUSTRALIA .you were a great help 👌👍
What strange speech mate? ;-)
@@SurvivalOnPurpose haha cheers mate .Have a good one .
If you're looking for a US lensatic compass on the cheap try keeping tabs on your local auctions. Especially if they post pictures before hand that you can look through like on facebook or something. I nabbed a 2005 Cammenga tritium compass for $25 and a slightly older Stocker and Yale compass (same compass just made before Cammenga was founded in '92) for $20. Tritium glow on the Cammenga is a little weak now that its 15 years old but for 25 bones it was a steal all the same. Just a tip for ya'll not wanting to spend $80 on a new Cammenga.
cool
Excellent explanation.
Thanks. I'm glad you think so. I really did my best to make it simple.
You should do an in-depth video on magnetic declination and the agonic line.
In depth?
Good video. Great content. Thank you.
Nice video! Good job of explaining.
Glad it was helpful!
Really enjoyed this video. You don't try to make land nav sound like rocket science. I haven't used a compass since my Boy Scout days in the 70s
Well...it ain't rocket science. It actually more like geographical science ;-)
Great information on how compas
Glad it was helpful!
I wanted to see you use the one with the mirror on it. Most people cannot clearly explain what the mirror is for. Maybe you have a video about it I will check your list.
Very, very helpful.
I would like to know how you work out your exact GPS co-ordinate from a lensatic as I've a NATO issue version with the tiny look thru viewer an notch style azimuth sighting.
Thanks for a good video very good explanation! Mine is a model 27 phosphorescent. Is that like the one you demonstrated?
Excellent how-to.
Glad it was helpful!
All my lensatic compasses are Commega compasses. I have two of each the tritium and the phosphorescent.
Cool
Great video, how do you find your position on the chart so you can create your heading?
search my Map and Compass series from a few years ago
This was genuinely helpful.
I am genuinely glad it was.
I'm a bit on the back foot as to the accuracy of those two devices.
The Camenga is pointing North at about seven o'clock. The Suunto is pointing North at about eight o'clock.
One is way off...but which one?!
Excellent video! Thanks!
i have a British army lensatic compass but it doesn't have a straight edge to it , can you help me on how to use it
Thank you!
How about going around a mountain, hills, etc. Instead of a straight shot across an area?
Thanks Brain
I have a rough/basic idea about how to figure out how to find my way.
My problem is, how do I figure out where "I AM"(starting from)
Maybe this old video I did will help. th-cam.com/video/viDBOYQV51M/w-d-xo.html
Thank you very much, very well explained
Glad it was helpful!
Hi. Do you happen to have a compass (Lensatic) video that doesn't use maps? For instance, if you go on a hike that uses trails but then you find yourself lost due to multiple trailheads and you took one too many. So then you have to get back to your parked car. Or, you are on a drive and have taken multiple small country roads and now find yourself lost. In both cases, no maps seemed necessary at the time.
Thanks,
Eric
I have an older series about several compass topics that you may find helpful. But, if you haven’t kept up with which way you went or have at least a reasonable knowledge of the surrounding geography (some sort of “map in your head”, then I’m not sure a compass is gonna be much help.
@@SurvivalOnPurpose Great, thank you.
Reading a compass is a skill i want to learn. Next time could you do one with the base plate model? Thx
Check out this playlist: th-cam.com/play/PLlvBLL5-fJbjKV34J5pvApsrMrrpJhRzE.html I made those videos a while back. The first one about getting free maps is pretty outdated because the USGS website has changed, but the rest are valid. Honestly, if I need a map I buy it from MyTopo.com. You can create custom centered maps in a variety of scales and get them on water-resistant, tear-resistant paper for about $16 or so.
4:23
Still confused. You oriented your map to magnetic north; you found your direction of travel based on the magnetic north orientation. When did you account for deviation?
If you are just planning a route using the map, and the map is oriented toward magnetic north and the compass has not been adjusted for declination (which means the needle points to magnetic north) then there is really no need to account for deviation because your map and compass are speaking the same language.
Thanks, your reply clears things up.@@SurvivalOnPurpose
If lost in wilderness in Southern Hemisphere do we always travel “North” or “NW” direction? or do we travel “South” Plz help.
That would depend on which direction you need to go. There is no "always travel" direction in either hemisphere.
GREAT VID!I HAVE A MILITARY ISSUE L.C.......DURABLE,SOLID,&PRECISE!
yep
Good to the point tutorial.
Thanks
Thank you for a clear and concise description. You took a lot of the mystery out of using a compass and saved me money and buyers remorse. I just completed the purchase of a Cammenga 3h
Not very clear and concise description at all. Alas!
I have a lensatic compass and when I hold the compass up horizontally and square the sight slot appears to be out of line with the sight wire. Is this an issue as my other compass appears to line up on the wire better. This is a National Geographic Lensatic compass and the one that lines up better is called Engineer
It could be a problem. It is hard to say without actually seeing it.
I live in Arizona do I need to get a Northern Hemisphere or Southern Hemisphere compass
northern
Brian, where do you get your maps?
Mytopo.Com
Great video on Lensatic Compass use and thank you!! How do you feel about using it in conjunction with a GPS? Transferring GPS magnetic bearings to the Lensatic Compass for navigation? The GPS works great with a baseplate style compass!
I have no experience at all using a GPS. (Except Google maps)
Please, more like this
I'll try
Easier then I thought. Similar to using a scale rule on a blueprint.
Exactly
All i really need to know is which one to put in my pack that will save my life if im lost and do not have a map . Because those little key ring compasses literally point North in every direction. I have three of them and they can literally get you lost in Walmart And how do i take a reading from the start of my hiking trip to get back to my car
I use a brunton 9077 brunton tru arc 5 and tru arc 3 and my garmin etrex 30x when hiking I carry 2 compasses and my gps and when prospecting (looking for gold) my tru arc 5 and my gps and switch maps from back pack to backpack you should check out the book (wilderness navigation) it says NO F**KEN AROUND HAVE A BACK UP but the book s really good california is huge the one place I have been going into is 2,700 square miles and the forests get bigger here
Backups are good
thank you
You're welcome
What’s the best way to store this compass? I know your not suppose to store it near metals but I was wondering if you could carry it in an EDC but would still it be effected by metals (cars etc) you face everyday even when the magnifier locks the compass?
I don’t think storing it around metal hurts it. Just make sure it is not too close to metal while you are using it.
Survival On Purpose ok thanks
Thanks for making this video I have a lens etic compass it says it is Waterfield he does a big bubble inside I know what direction North is from where I live but this compass points South to North and North to South I am more confused than a rabbit with rabies can you please explain if this is correct and what am I supposed to do as I feel like hitting it with a hammer hahaha just joking but it really is a hard compass to use I always thought you pointed a compass with West pointing away from you and North should be on your right but I am only trying to learn if there's anything advise you could give me it would be much appreciated thanks American from Australia.👍🇦🇺🇺🇸
Archer 001: You can get compasses which only work correctly in the Northern hemisphere OR the Southern hemisphere.....it sounds like you're using a Northern hemisphere one in the Southern hemisphere (hence the back-to-front readings.....your North needle will point South & Vice versa). You can also get a "Global" compass which will work anywhere in the world.
I would love to have a Cammenga compass. It's a little out of my price range. With that said . What do you think of the Eyeskey millitary style compass? From the reviews I have read they seem to be fairly accurate.
I'm thinking of getting one till I get the money for a good Cammenga .
I have no experience with them. I will say that I need a compass to be more than "fairly accurate". For the same money you can get a Suunto MCB amzn.to/3eqai7M and for about $47 you can get the MC-2, which is an excellent compass amzn.to/2NeBcTY
7:58 So basically, you WON'T be looking down like that. You will put that lense much closer to your eye such that when you look through the lense you can see the compass dial, and when you look up _through the gap at the top of the lense_ you can see the wire. It is very important to look at the sighting wire through the gap because that allows you to have both the wire and the objects in the background in focus at the same time.
You can do it either way. The "eye up close" method is more accurate.
