    It's wonderful news to read Silva Sweden has acquired ownership of the Silva name in N America and started importing your compasses again with US models starting Jan 2018.
    Also terrific to see you now have compass models with global needles .

    Silva is a swedish company, we hardly have any declination over here so the few degrees declination some areas have is so small it dont matter, but yes, if your area got substantial declination you will need to correct your bearing.
    But if you didnt notice, this is all very basic land navigation skills, correcting declination comes in the advanced classes along with pin pointing your location, this is preschool stuff, the basics everyone needs to know to get you in the correct general direction.

    2:11 statement is true if magnetic north is equal to true north. Or those lines on the map are drawn in magnetic lines. Declination must be considered and should be mentioned.

      Those lines would almost certainly be grid meridians -pretty close to true northings.

    Forgot to mention Ranger beads and pace counting. Other than sighting a target in the direction of travel and walking to it, you may need to estimate the distance that you have traveled if there is no point of reference on the map. In essence, you need to know how many times your left foot strikes the ground in 1 kilometer with the load you will be carrying in the type of terrain you will be traversing. Ranger beads are a convenient way of recording each 100 meters to one kilometer.

    • @annar8759
      @annar8759 10 років тому +3

      Ranger beads are best, but I find I never have them when I need the. You can move pebbles from one pocket to another, keep one more finger out of your pocket, tie a loop in a string etc. The important thing is, have 2 pacers. The average of 2 people gives a more accurate number than 1. Keep in mind that your load, fatigue, ground conditions (ie walking in sand, snow or swamp) will all effect the number of paces it takes you to go 100 m. AND when 1 pacer screws up, he should immediately announce it and start again at his buddies numbers.

      Been route marching, and on land expeditions for over 40 years, in many differing types of terrain, and have never yet used ranger beads, ever. You should know your average walking pace, and how long you have been walking, then the rough calculation is simple.

    Unfortunately not. The products sold in the US under the Silva name are cheaply-made by a different company, there was a big trademark/distribution dispute you can read about if you wiki "Silva Compass."
    To get true Silva AB of Sweden instruments, you either have to find them on eBay, travel to Sweden, or have someone in Europe to ship it to you. Retail stores in the USA cannot legally sell them.
    The best option to a real Silva available here I believe is the Suunto M-3G Global, about $45.

    This is a very simplistic video and completely disregards magnetic declination. In some parts of the world, FT Lewis in WA state as an example, magnetic north and grid north varied by no less than 23 degrees. Even on short legs that can result in significant errors. For a 23 degree difference, you would be off by no less than 42.4 meters on a 100 meter leg, (the tangent of 23 degrees is .4244). That is enough for you to completley miss your mark. On 300m, it is 127m, more than a football field!

That's a difference between arriving at your landmark and arriving at a similar looking landmark you think is the correct one. With 25 degree declination we're talking almost 1 km error after the same 2 km.

The only situation where you don't have to know the local declination and adjust for it is if you can get the [magnetic] heading from somewhere else than from a map with geographical grid lines. If the "up" of a map is towards the geographical north rather than magnetic north then you will have to take declination into account.

      @@Gekkibi this is an excellent point. When going from map to compass there are three techniques to correct for declination:
      1. Depending upon whether the declination is east or west, add or subtract the declination from the true bearing to the objective determined on the map;
      2. On the map, draw (in pencil or on an overlay) magnetic meridians and use those to determine the bearing to your objective rather than the true north meridians;
      3. If your compass allows for it adjust the magnetic north indicator by the degrees of declination east or west; now your compass will point to true north and you may use the true North meridians on the map to determine the bearing to your objective.

    Go to www.ngdc.noaa.gov/geomag-web/?useFullSite=true
    Remember - "East is best ( add +), West is worst ( substract -). "
