IntenseAngler’s “Tip Of The Week” – Episode 9. How to accurately determine your position with a map and compass. This navigation tip is not only a useful outdoor skill to have, but one which may be a life saver as well. This week’s tip is brought to you by our special guest host, Paul from BCoutdoorsurvival. Thank you Paul.

  1. Mmm maybe I do! But can't see right off hand why it wouldn't work.

  2. good video, I think for me, it'd be easier to never adjust my compass for deviation, and just lay it on the mn grid deal arrow, and rotate map till whole thing compass and map say n. that way i don't have to ever fiddle with adjustments. when i travel to different areas., i understand though it should always be a very current map

  3. sometime i can't tell mountains apart, so i have difficulty to make decision on where i am on the map.

  4. If you can identifie 2 locatoins on the grond and on your map you should know where you are so resection would not be necerrary. saves a lot of faffing about

  5. What compass did you use? Can you tell me the name of it ,please.

  6. another way to do a resection is to find a sure prominent feature, shoot a bearing and mark it on your map. do a 90 degree turn left or right and pace out 100 meters and shoot another bearing to the same prominent feature and mark it on you map as well. then use a roamer/protractor and slide it down your 2 lines you made with your bearings until it reaches the 100 meter mark. iv done this on a 1:50,000 map but it is not as accurate as having 2 prominent features as mentioned in this video. Great video by the way!

  7. Brilliant presentation, never knew how to do this, will try this out tomorrow, if I make it back I'll post how it went. If I don't post tomorrow it will mean I got lost.

  8. I bet you had some good tips in your video. Unfortunately, your video was about three minutes too long for me to watch. Cut down the length of your videos and I bet you will get a lot more hits.

  9. Ei Pi

    thxs ! nice vid

  10. Very good video. But I have noticed that a lot of mountain tops just look the same to me. Will the same method work even if you are not 100 percent sure that you are sighting at the right one? That is if the map has been lined up with true north. I think this is harder to do than what most people understand it to be. Most people think they can do this until they really get lost off the trail.

  11. Where can i find these maps? I can never seem to find the one i need.

  12. Cool i'm learning a lot! Thanks for those awesome vids.

  13. It's also called 'triangulation' (because a (invisible) triangle is formed from the two features and yourself.).  You can also use 'resection' by using just one feature if you know you are currently on some linear feature on your map like a road, trail, river, creek, under a power line, etc. Where the drawn line from that one feature on the map bisects the linear feature you're is exactly where you are on it.

  14. this is better then an expensive GPS device and it´s cheaper and accurate.

  15. Resection works only if ALL THREE of these conditions are met:
    1) You can see landmarks.  If it's dark, low visibility, snowing etc this technique fails.
    2) You can match landmarks you see with your map.  Even if you can see a lake or a peak, if your map has several and you don't know which it is, this technique fails.
    3) You see a landmark and you can identify it, but it's not printed on your map as it;s too far away.  This technique fails.
    So, you can see that 3 favorable conditions ALL have to be met for this to work, and it is thus NOT a technique you can rely on in every case to get unlost.
    Consider this as an alternative:  Get a smartphone GPS app like IHikeGPS for $10, turn it on, and bam there is your position on a nice base map.

  16. Suggestion: spend an extra $10 and get a quality compass with adjustable declination. The Suunto M2 or M3 is a great choice, about $25-35.
    Set the declination once for your home area and forget about it.  After doing this, all bearings are to true north and you have no need for confusing backcountry arithmetic, most likely needed years after you watched this video, when you are lost, wet, dark stressed, etc and can't remember  whether you add or subtract the declination. 

  17. this method of determining where you are on the map will work with either kind of compass..also to add on the info in this video the more landmarks you use and make the lines on the map the more accurate it is. its recomended to use at least 3 or more landmarks..once you figure out your position the compass with the mirror is quite a bit more accurate navigating to where you are trying to go when you know your bearing ..
