morning folks I'm Dave Canterbury with self-reliance outfitters in the pathfinder school back in another in our series five minutes to better bushcraft and today we're going to talk about the angular advantage and the only thing you need to remember about the angular advantage is the number forty five forty five degree angles will do a lot for you in bushcraft we're going to talk about that right now okay let's talk about this forty five degrees if we have a line this way and a line this way and we have a 45 degree angle here then this distance and this distance are going to be equal and we can use that on the ground or we can use that in the air to our advantage if we want to know the height of a tree and we get back from that tree on a 45 degree angle to the top of that tree and we find a 45 degree angle with our clinometer which we'll talk about in a minute we are the same distance away from that tree as it is tall plus our body length because we're standing up so we'd have to be laying down you get that 45 degree angle again so we add our body length to that measurement that will tell us how tall that tree is we can use that for lots of things if we're going to fella tree we want to know how far it's going to fall where it's going to land we can figure that out if we have a tree that's dead fall in the area of our camp we can find out how far away from that dred fall we need to camp to be safe if we're going to drop that tree across a danger area like a Swiftwater crossing and we want to know that that tall tree is tall enough to reach the other side we can measure that how do we find out what the link is across that danger area we use the same method on the ground if we have a Swiftwater crossing here a danger area and we want to know what this distance is here because we're going to drop a tree on this side to give us an assisted handrail across that crossing then we need to find a tree on this side to take a bearing on with our compass and then we walk in this direction until we are 45 degrees in either direction from that azmuth and that gives us the distance from here to here equal to the distance here which tells us exactly how far it is across that danger area okay let's say we're trying to do something mapping and we want to do some contour mapping and we have a hilltop here and we have our buddy standing somewhere on that incline and we're standing down here at the bottom we can use that same angle if we get away from him at 45 degrees then we travel this way until we are 45 degrees again here then this distance is the same as this elevation if this is our zero elevation this distance equals the elevation here we can spot check that in several places and just connect the dots to create simple contours this is a more complicated mapping method but it's a simple way to use the same thing to affect a somewhat accurate contour if you are trying to do something the other way that we can use this if we are trying to navigate from a camp Serah campus here and we are camped along a linear feature because we understand that aiming off and things like that will help us to stay found if we take an azimuth here and walk a certain distance and we know what that distance is because we keep track of it and then we make a 90-degree turn and walk an equal distance in either direction so there's equal here or here then this angle should be 45 degrees to get back where it came from and if we aim off and then we can't drift into our camp or if we hit this linear feature know exactly which way to turn to get back to camp but this 45 gives you a leg here and a leg here which would give you an exact asmath back here at a straight-line distance back to your camp and about one and a half times the distance of either one of these legs okay guys well I'm Dave Canterbury with self-reliance out there is a path lesson when I appreciate join me for this quick five minutes to better bushcraft on the advantage of angles or the angular advantage I appreciate your views I appreciate your support and thank you for anything you do for our school for family report business all of our sponsor instructors affiliates and Friends I'll be back to another video as soon as I can thanks guys
