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 👍.

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

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 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.

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 😊

So just a quick tip about using a permanent marker, and removing its marks. You can make a new mark directly over the one you want to remove, and wipe quickly. Why does this work? Because the pen contains the same solvent required to make the ink flow initially.

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. kzfaq.info/sun/PLtmTvvlTrlahCoV4mgSzG6s_gF4xLLUU_

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.

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!
@TheMapReadingCompany3 ай бұрын
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.

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.
@Cous1nJack3 ай бұрын
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.

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!
@TheMapReadingCompany4 ай бұрын
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.

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.
@brandynrudolph8 ай бұрын
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.

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.

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")
@kirkhamandy9 ай бұрын
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.

I may have missed something. Would you please clarify: in order to do the triangulation method did you undo the declination?
@survivalzoneswitzerland66979 ай бұрын
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
@TheMapReadingCompany9 ай бұрын
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.
