Very informative video, clear and concise. FYI...Benjamin Franklin was not a president of the United States. However, he was a "Founding Father" and a signer of the Declaration of Independence. Thanks for all your videos.
Without doubt the best I’ve come across on the net for explaining all types of navigation . Truth is , these days a lot rely heavily on phones and gnss devices, so these videos are like refreshers as well as picking up new tips, and definitely give me the inspiration to brush up on what I learnt years ago. Thoroughly enjoying wading my way through your videos having only just discovered your channel. Thank you very much sir 👍.
I so appreciate your videos. I am in N. America and I explore areas in the state of Utah... feeling comfortable with map and compass (bearings and such) are very important to me. Thank you.
These videos are very interesting and extremely helpful, even to those of us who stay on the marked trail in cell service areas! Just watched basic parts and Naismith rule. Many thanks for your time and work.
Interesting etymology for "triangulation"... When my ex-navy-radio-operator grand-father was explaining to me the concept of triangulation (applied to RDF, he did a lot of SIGINT back then), he never mentioned error-margins or fast-moving boat resulting in a triangle-shaped intersection rather than a point. Actually, I always assumed it was named "triangulation" simply because when you measure bearings to 3 points A,B,C : A,B & C are the 3 corners of the ABC triangle. Thanks for your alternative etymology : it makes sense and will help me memorize things better.
I've found a permanent marker or chinagraph can be removed from laminated maps by using a pre injection swab. They come in small neat wrappers a bit like lens wipes but stronger. It's a method recommended by another well known navigation company. No names mentioned. Keep up the very good work Wayne.
Great videos. I used a compass last time 30 years ago as in Polish mountains usually a map is enough - we have a lot of marked tracks. But your explanations and tricks are very interesting, so I watch whole series :-). You can use markers for whiteboards. They are not permanent. Or you can use WD-40. Should be able to clean this. And alcohol, of course.
I'm really enjoying the information.. thank you .. when I was in the Fire Service, we had to keep Breathing Apparatus entry records for our personnel (to buildings, etc.).. being outside - it often rained.. so, we used a chinagraph pencil to write on our plastic boards (they're readily available and reasonably cheap).. its soft wax like pencil, it doesn't make as fine a line as a sharpie, but it's waterproof, fairly resistant to smudging, and easy to wipe off (we used a bit of wrag kept fir the purpose).. just an idea to try out 😊
In the US they are called grease pencils and are used for marking on glass or china. We used to use them for marking audio tape back in the day when we edited with razor blades.
When you put a map in one of those clear cases, make sure to reference the case to the map. It’s super easy to do. Just find where two grid lines intersect, draw a cross, and mark the easting and northing on the cover. This way, you’ll always be able to line up your waypoints and transit lines later if you need to. And guess what? They’ll translate from the cover to the map in the correct places! When you get home, just run a dry erase marker over the permanent Sharpie, and it wipes right off. A better pen to us is the Stadelter Lumocolor markers with a super fine tip. They come in a 4-pack: red, green, blue, and black. The lines and dots they make are way more precise.
Agree with Edward's comment below - for anyone interested in developing or maintaining their navigation skills - this channel is excellent, full of great info, tips and methods and the occasional wonderful waffle moment! Check out the gate video....
Great video Thank you for doing this channel. I've never done compass / map reading before, so your guides are very usefull. Only thing I'm worried about is being "Lost" and trying to triangulate where I am. This really worries me
I would suggest not starting with back bearings. One way of starting to learn navigation is to buy a map of a local area which you know - so you won’t be worried about being lost. I would suggest asking the shop for a 1:25,000 map, so there will be lots of details on it. Go to a place you know (e.g. Sutton Park?) and try to identify any features such as roads, tracks, rivers, bridges, building, hills, etc. Walk towards one of those - try and follow your progression on the map by looking to the left and right and see if you can see anything shown on the map - then, when you arrive, identify another feature and walk towards that. If you cannot find your location on the map at any time you can always go back to your last known position. Next, once you're happy you can follow a route on the map, try using the same map - as they tend to cover quite large areas - and go to an area which you haven’t been before and just use the map to navigate. You won’t need to use a compass to start with if you stick to tracks and lanes. Have a look at this play-list and it will start at the very beginning and work up from there. ruclips.net/p/PLtmTvvlTrlahCoV4mgSzG6s_gF4xLLUU_
PS I have an introductory course in the Shropshire Hills (Church Stretton) in Sept. Have a look on our website at the end of next week when all the autumn courses will be up. Bronze Level course details are here: mapreading.co.uk/
As a scout, soldier never listened to any about back bearings. I've always rotated the compass ( using it backwards) this is the first time I've heard someone else talk about it. Once you have done your calculations for mag to grid, on top of compensation for year map( was in scouts ,maps always years old) why bother working out what 180 is. Plus if it s dark ,raining ,cold and your wearing gloves. Just check your dail to see if still set on orginal bearing, then use it backwards. Nice to see people still using maps. GpS and phones need batteries and signals. Maps just need a plastic bag to keep them dry. Remember you are only lost because you went one step to far from remembering how to get back to a place you knew where you was.
Actually gnss devices work off satellites - mine off 5, and phones you can download routes offline. I have a Garmin 66sr and it is incredibly accurate(less than 2m), robust, and battery life last for days or even weeks in the right mode. 100% believe in being totally confident with traditional methods first, but then equally embrace the technology. All adds up to a more enjoyable experience in the wilds :-) cheers
All the navigation videos that I watch regarding back bearings, no one ever mentions the easy 200/20rule. I learned it in flying to make the calculation easier than adding or subtracting 180°
I once heard a tank soldier being interviewed by a newscaster after their tank had been hit by friendly fire in Iraq, and the newscaster asked him how they wound up where they were hit, asking if they were lost. The soldier replied, "we're never lost, just disoriented." When navigating, I never forgot that. If you have compass skills you can always get yourself oriented. Also, as far as taking a back bearing, I find it useful for getting back to camp or my car.
Regarding the section on transits, when you take the bearing to the reservoir do you then put Fred in the shed before transferring to the map? I get very confused about this still!
When you take the bearing using your compass you point the compass’s direction arrow at the feature and rotate the dial until “red is in the shed”. When you transfer this bearing on to your map you put the edge of the compass on the map so that it’s touching the feature. (don’t move the dial whilst doing this). Keeping the edge touching the feature, rotate the whole compass until the orienting lines are point straight up the map (northwards). The edge of the compass will now be touching the feature and also running though the track that you’re on. When the edge cuts through the track - that’s your position.
Question: Is there a reason you rotate the compass until the orientation lines match the grid lines, instead of setting the compass down so that the orientation lines match the map, and then sliding the compass down until the edge of it (or parallax line) hits the feature you're triangulating from? Thanks!
At 10:30 in the video I’ve taken a bearing and set my compass to that. When you put the compass on the map the bearing on the compass doesn’t change so you need to rotate the whole compass (without changing the dial) until the orienting lines match the eastings on the map.
Awesome video as usual.......Question though. Why is it that when doing triangulation, resection and transits, are they referred to as "Back Bearings" ? When you're only taking a forward bearing ? Thank You.
😊 well I’ve never been asked that before. For the past few years I have used AltBerg Kidson. They are “G fit” which means they are slightly wider than some other boots. These are good quality 3 season boots, but they are a bit expensive. www.altberg.co.uk/boots/gfit-boots/kisdon
Another excellent video! I found your explanation of the rotation method for circumnavigating an obstacle (or otherwise recovering from drifting off course) was not entirely complete. It certainly left me a little confused until I checked it in the field. What is not mentioned is that it only works if you can sight your last starting point (ie when you took your last bearing). The steps to follow are: 1. Turn your body to directly face your starting point. 2. While holding your compass in front of your body and always pointing towards your starting point, walk left or right until the black/white end of the compass needle is back in the shed. 3. Turn your body 180 degrees and put red-in-the-shed. 4. You are now back on course.
I've never used maps and compasses, and that's why I'm here. However, we used to use Chinagraphs at Pilkingtons (pencils - not graphene though) to write on the monitors',glass, metals etc to keep track of the glass position etc. Would that be better than a permanent (Sharpie) pen? Although the nail polish may be useful for also doing your nails and lighting a fire or burning yourself.
I'm confused about adjustment for magnetic declination. In you video on that subject you say if magnetic declination in 10 degrees west you ADD 10 degrees. If east, SUBTRACT 10 degrees. In this video you say the opposite. Which is it? Great videos by the way. Thanks
Hi Matt. It depends where you’re getting your bearing from. If you use your compass to take a bearing and you want to transfer this on to your map (like in the Back Bearings video) and your declination is West you subtract the amount of declination, if your have an East declination you add it. If you take a bearing from a map and want follow it (like in the Declination video) and your declination is West then you add the amount of declination, if it’s East you subtract it.
That calculation method drives me crazy. As much as I love math, adding and subtracting always bogs me down. I try and use at least the four compass points to calculate from instead (360 180 270 90) and then visualize the rest. So if I'm reading 80 degrees, I know I'm just over the other side of the 270 of the compass by 10. Helps me a lot. Probably would be easier even if I could manage to memorize 8 points of the compass rather than just four too. But I manage 😋
I have to chuckle - my wife is navigationally challenged and gets very anxious about it, but I worked, lived and hiked for years in the million acre Mt. Hood National Forest and knowing my compass directions is just a habit now. When I tell her in the car "We're not *lost*, I'm just not exactly sure where we are right now" - oh, the look I get!
for a recection with a compass you only need 2 bearings... (the third one would be for confirmation? if it doesn't coincide with the previous ones there is something wrong.)
It doesn't work in half of the UK (and all of it by the end of 2026). It also doesn't work in half or the world. See here for a better method (WAvES) ruclips.net/video/Tf9rrmq5Vf8/видео.htmlfeature=shared
You could use a dry erase marker to make your lines, or for a life hack- you can remove permanent marker from a whiteboard, laminate etc but going over the permanent marker WITH a dry erase marker and simply wipe away :)
It's best when triangulating a bearing to make sure all three points are far apart on degrees to insure as accurate a position fix as possible. On land it is not as necessary as at sea.
But not so far as they become reciprocal. 60 deg is optimum. 1deg at 1 mile is 200 yards so easy to be inaccurate in any case when taking a bearing with a baseplate. 2 or 3 degrees error at 1/2 miles is easily 300m per measurement and a cocked hat covering a whole grid square.
Oddly if you you have a permanent line marked (of any age) on any surface it can be removed by drawing a line on top of it using a non permapen. After applying the line while it is still wet just rub it with a cloth and it should remove the marker pen line.
Even more oddly you can also use a permanent marker to remove the line to. Redraw the line with a permanent marker and wipe it clean just after doing so. I used a permanent marker on a white board to intentionally create a permanent grid pattern but many months later I no longer had a need for it. After trying many times to remove it unsuccessfully a friend of mine showed me the trick. It worked surprisingly well. It seems to me that it might also work on plastic map covers.
The 3rd method, transit, description I found to be odd, I was never taught it probably because forests, walls, and boundaries change a lot and can differ from the map and I was taught to contour read distance hills, especially peaks, and use these (I haven't watched the entire video yet so maybe what I described I do will be the last method, "triangulate")
Now I've watched to the end and yeah, that last method I mostly use. And thinking more, I do use transit lines when on path but I always choose contour-defining points rather than "features that could change". Great video though, all methods are clearly explained and demonstrated.
Do we really need to account for declination here in western Europe, i mean most of the time there is something in the way like a prominent feature, a tree, a wall, a fence and so on therefore we tend to spend most of our navigation time hoping from one to another. I think that as the distances we use are generaly so small that those few meters are not a problem, however I do agree that if we were in a desert and navigating to the only water source for several hundred kilometers that then it makes a real if not life life saving difference
I’ve always said, and some people may disagree, that when we’re out walking, if the declination is less than two degrees it’s not worth adjusting your compass for. Most cheap compasses aren’t that accurate anyway so they may be out by a degree or two anyway. But you also have to remember that these videos are watched by a lot of people (over a million people a month according to my YT analytics) and many (most) of them don’t live in Western Europe. In some parts of the world the declination is significant and so it’s essential to adjust the compass before setting off.
Yes you're right. Thanks for the comment. I did include the 200 + - 20 to start with but the video started to get way too long so a few sections were deleted in the final edit.
Not in the rain. To easy to accidentally run off. Grease pencil is used for this type of work all the time. And... alchohol work fine on removing sharpie.
"Sorry, no offense meant". Someone else told me he wasn't a US president. I'm not too bad with English history but other countries . . . . obviously not 😊
😊 Not many Yanks follow this channel I guess. So I will have to chime in. Franklin was an American, but he was never president. Although he has been called The First American

No need to apologize. I was just responding to your statement. I appreciate all the effort that you put into your videos.
Sorry for the error - I'm not good with other country's history
@@TheMapReadingCompanyno worries, lots of my fellow Yanks also think he was a president. Maybe because he's on the $100 bill?

You could also use a thin piece of tape temporarily on your map case
for a recection with a compass you only need 2 bearings... (the third one would be for confirmation? if it doesn't coincide with the previous ones there is something wrong.)
True. Only 2 are needed for a 2D environment (like a flat map) and 3 needed for a 3D environment.

I may have missed something. Would you please clarify: in order to do the triangulation method did you undo the declination?
Isopropyl alcohol will nicely remove Sharpie- less caustic!
Thanks.
I use hand sanitiser to remove permanent marker. Plus you can sanitise your hands.
have you tried using a dry erase marker? You can run the dry erase marker over your permanent marker line, then use the dry erase both marks.
Won't hold up in rain. Grease pencil (what they are called in the US) works well. Or use alcohol to remove sharpie.
Thanks

You can also over-write the permanent marker with a washable marker and then simply wipe off with a tissue.
A sharpy will reactivate a sharpy. So draw a new fresh line over the old line and quickly rub it off.
Thanks, I'll give that a try. Sounds like a good idea.
👍
Do we really need to account for declination here in western Europe, i mean most of the time there is something in the way like a prominent feature, a tree, a wall, a fence and so on therefore we tend to spend most of our navigation time hoping from one to another. I think that as the distances we use are generaly so small that those few meters are not a problem, however I do agree that if we were in a desert and navigating to the only water source for several hundred kilometers that then it makes a real if not life life saving difference
I’ve always said, and some people may disagree, that when we’re out walking, if the declination is less than two degrees it’s not worth adjusting your compass for. Most cheap compasses aren’t that accurate anyway so they may be out by a degree or two anyway.
But you also have to remember that these videos are watched by a lot of people (over a million people a month according to my YT analytics) and many (most) of them don’t live in Western Europe. In some parts of the world the declination is significant and so it’s essential to adjust the compass before setting off.
Denatured alcohol will remove almost all types of sharpies, except textile markers.
In the UK it's called Methylated Spirit. Nail polish remover is cheaper 😉
Uups... Quite the opposite here 😆
Rubbing alcohol works fine, too.
Ben Franklin wasn't a President. He was the inaugural winner of MasterChef the Pioneer Days.
+ or -- 200 then - or + 20 gets the back azimuth quick.
Yes you're right. Thanks for the comment.
I did include the 200 + - 20 to start with but the video started to get way too long so a few sections were deleted in the final edit.
whiteboard markers might be better those will just rub off
Not in the rain. To easy to accidentally run off. Grease pencil is used for this type of work all the time. And... alchohol work fine on removing sharpie.
Geographically misplaced lol rather than looking over strange terrain
Alchohol removes sharpie. We do it everyday.
Never Lost. Just disoriented
Isopropyl Alcohol will remove Sharpie from nearly anything!
American President? Bruh
"Sorry, no offense meant". Someone else told me he wasn't a US president. I'm not too bad with English history but other countries . . . . obviously not 😊
"Its important to remember a famous saying from the American President Benjamin Franklin" ... *laughs*
"If he wasn't American, I apologize"
Whoa.
😊 Not many Yanks follow this channel I guess. So I will have to chime in. Franklin was an American, but he was never president. Although he has been called The First American
