    I often intentionally do not plan, and often take risks, because surprises are way more fun than playing it safe or having everything all planned out in advance. After all, one of the main purposes of a compass is determining where you are, not just where you are going. Also, after watching many compass "how-to" videos, it occurs to me that most of them don't discuss why exactly you go through these various steps. As a result, people may forget the steps and make navigational errors because they don't understand the rationale behind the steps. Best to know the why as well as the how. Not so easy to forget that way, IMHO. With respect to a compass, this is actually pretty easy. A baseplate compass is essentially two tools combined: a ruler and a protractor. The purpose of a ruler is to draw a straight line between two points to establish where you want to travel. Then the protractor is used to establish your angle of travel (your "course") with respect to North. If you remember simply that, you'll remember how to use compasses. Many thanks.

    new to this stuff, so not really qualified to talk: but that's never stopped me before. appreciate it if someone who knows more sees an error and points it out to me.
    meridian lines ARE true north/south. if the map has them, use them directly to orient the arrow on the bezel to the bearing you want to take, or the azimuth you want to shoot. now the reference to calc your bearing is the needle itself. and that INCLUDES the declination adjustment, the actual magnetic heading is 360 minus the angle of the needle to the arrow. if map doesn't have meridians, it will have a compass rose (if it's any good) that shows a true N/S axis line, then you use that to make your declination adjustment, line up the compass body w/ N/S axis on compass rose symbol on map, move the compass to the part of the map you're using(maintaining that orientation), then rotate the bezel (as above) so that the arrow points to your bearing. either way, if your magnetic needle is pointing to 35 degrees, then your bearing is 360 minus 35 = 325 magnetic. assuming terrain allows you to proceed directly toward your bearing and that's what you want, then that's your heading.

    I've watched several videos regarding map and compass skill, and this one is perhaps the most useful yet. Anyone wanting to learn this stuff has to accept that no one video will give them everything they need, so watch as many as you can until it begins to make sense. Explanations that I didn't like very much went don't very well with others (based on the comments). There are also some good ones out there on declination too.

    A powerful video, I simply given this onto a colleague who was doing a bit of evaluation on this. And he in actual fact purchased me breakfast as a result of I discovered it for him.. smile. So let me reword that: Thnx for the treat! But yeah Thnkx for spending the time to debate this, I feel strongly about it and love studying extra on this topic. If possible, as you develop into experience, would you thoughts updating your video with more particulars? Its highly helpful for me. Large thumb up for this video publish!

  • @ghostmode9824
    @ghostmode9824 9 ปีที่แล้ว +5

    I seriously got a question here! In the video at 3:30 (STEP 2) it says that the lines should be aligned with the map's meridians. BUT, if I live in a place where the magnetic declination is tremendous and I have adjusted my compass to compensate the declination, then my bottom Arrow will no longer be parallel to the compass' bottom lines which should line up with the map's meridians. So in this case do I still line up the compass' bottom lines with the map's meridians or should I line up the compass' arrow (shed) with the map's meridians???
    Also, when magnetic declinations has been set, should the cardinal N mark still be parallel to the North on the map, or should I line up the new compensated North Arrow in the bottom of my compass???
    No one really covers this issue, at least I could not find any :-(

      @pay9011 ปีที่แล้ว

      I'm sure you've resolved this by now. my understanding is that in step 2 you turn the bezel until it aligns with the proper amount of declination found on the declination markings (instead of the large N).

  • @Theenemy38
    @Theenemy38 12 ปีที่แล้ว +2

    So let me see if I understand this. If I have a lensatic compass and I sight a landmark at lets say 80 degrees all I have to do is turn the graduation ring until it's pointing north on the compass??? Sorry if I anger anybody I'm just having a little trouble understanding it. Any help would be much appreciated.

      If you are navigating from landmark to landmark then declination isn't necessary if the distances are only a few miles apart each.

    • @kuttz12
      @kuttz12 4 ปีที่แล้ว

      You always have to convert a Grid Bearing to Mag Bearing. If not you will be traveling on the wrong bearing. Unless you map to ground it the whole way, but this is bad practice (in this case). Always convert to a mag bearing.
      We use the silva type 54, which is awesome but unlike the the old mirror compass u have to add or subtract the magnetic variation which is all good and easy to workout on the dial.

    I'm probably way off beam, but it was a British accent, very south east which also happens to have -0° magnetic declination. So perhaps they didn't demonstrate what they couldn't demonstrate in Britain. Declination could do with some futher information, such as, what does the term "negative declination west" mean? Very good video though.

    • @Steve_Farwalker
      @Steve_Farwalker 8 ปีที่แล้ว

      Careful with the declination reading on some older maps. According to NOAA magnetic declination is slowly moving west. Older maps with the printed declination can be off by 5 deg or more. Check the NOAA web sit for the current declination for your area. www.noaa.gov/

    • @johngo6283
      @johngo6283 8 ปีที่แล้ว

      To find your correct declination, go to magnetic-declination dot com. One click on the Google map shows the correct declination for any point in the world.

  • @Perktube1
    @Perktube1 10 ปีที่แล้ว +1

    Ok, so you need your map facing true north or magnetic north?

    • @BEstudent
      @BEstudent 10 ปีที่แล้ว

      By turning your map towards magnetic north, all the terrain features showed on the map will be in the same position in the real environment. Example: if I turn my map towards magnetic north and I see on the left side of the map that there is a lighthouse, I will only have to look to my left and indeed see a lighthouse (as long as you are not too far away from it of course).
      The reason why you align your map towards magnetic north is because magnetic north and grid north (the north on your map) are different. By aligning your map towards magnetic north you avoid holding you map "upside down".
      I hope this was easy to understand. Kind regards! :)

    • @Perktube1
      @Perktube1 10 ปีที่แล้ว

      Evert Clowting wait, if grid north on the map is different from magnetic north, wouldn't it be wise to align grid north to true north and simply mark magnetic north on the map? Otherwise the map is tilted.

      @@johncelletti3108 I second that on learning via practice (and confirm with instruction manuals/videos). It becomes easy to come up with a custom way of performing the steps that makes sense to each individual. I figured out declination pretty readily by just thinking of it as an offset angle that is added or subtracted every time. That will come in a lot more handy this summer traveling up to northeast Canada, into Newfoundland and Labrador. Up that way, there is a big 25-30 degree difference between magnetic and true north.

    5:15 in, big screw up in steps calculation. If your stride length is less than 1m, how can it take fewer than 100 steps to travel 100m? 62 steps at a 0.8m stride length is just under 50m, not 100m. Hope no one relies on this!
