I am giving this this version one famous person as a result of the details that follows.This version states--right at the cover--that it "now presents info on GPS." that's actually precise yet very deceptive. I had anticipated information regarding the right way to use GPS in addition to a map or compass, or utilizing GPS in simple terms. yet in its place, the only a few statements approximately GPS simply let you know that GPS is undesirable, and maps and compasses are stable. for those who glance within the desk of contents, you will not see any bankruptcy approximately GPS. visit the index and also you see merely 3 (that's correct, 3) pages which point out GPS. web page tells us how GPS does not paintings good in forests, canyons, and so on. Then visit web page 14 - 15, and you will find that Ms. Elgin and the publishers have been in this kind of hurry to make the most of the luck of the unique model, they could not even get the index correct. there's not anything on those pages approximately GPS, yet in fact if there have been, it is going to in basic terms be, back, that GPS is undesirable and maps and compasses are good.Perhaps the writer neglected that on web page 20, the booklet states that maps let you know concerning the geographic positive factors of the area,"not simply how you can get there, as with a world Positioning System." After this, i ended interpreting, even if I did glance through the e-book for whatever precious approximately GPS. i did not see whatever, and the index does not contradict this as, back, there are just 3 pages which supposedly supply info on GPS.It's unlucky that the author's daughter stumbled on it essential to dishonestly try to promote extra books with this phony "revised edition." i have ordered the former variation.

Example text

From Paper Circle to Protractor The paper circle with its sixteen direction markings is your first step toward using a protractor. As you probably know, a protractor is an instrument used for measuring angles. It consists of a circle made from a piece of metal or plastic marked in the 360 degrees of a full circle. The markings start with 0˚, go clockwise around, and wind up at the 0˚ mark with 360˚. Zero degrees and 360 degrees coincide. Some protractors, for ease of carrying, are semicircular.

Round the free edge with scissors. Open up the paper and mark the folds clockwise: North, North-North-East, North-East, East-North-East, East, East-South-East, South-East, South-South-East, South, SouthSouth-West, South-West, West-South-West, West, West-North-West, North-West, North-North-West, North. To make things simpler, you can just put N, NNE, NE, ENE, E, ESE, SE, SSE, S, SSW, SW, WSW, W, WNW, NW, NNW, N. Place this circular piece of paper with its center directly over your spot, or base of operations, with the fold marked “North” (or “N”) lying north on the meridian line that runs through your spot.

On a great number of topographic maps—among them the included training map—the contour level is 20 feet. On a map of a rather level area, the contour interval may be as little as 5 feet. On maps of mountainous territories, it might be as much as 50 feet or more. There would not be space for all of those 5- or even 20-foot interval lines. The contour interval of the map you secure from the USGS is found in a note printed in the bottom margin. It may say CONTOUR INTERVAL 20 FEET, for example, but you can figure it out for yourself by studying the numbers on the contour lines of your map.
