[QUOTE="CatShooter, post: 22918, member: 7"] The hight is where the object splits in the little window. To range, you look at something and bring the upside down image, and the rightside up image to the point where the edges (or some other features) intersect each other. But in order for this to be accurate, the point of intersection of the two images must be the same. For example, if you were looking at a 12" ruler, and #1 was at the bottom... as you raised the the rangefinder up, you SHOULD see each number hit each other when they come to the intersection... So #6 would dissapear from each edge of the window at the same time. IF they don't, and you can see #6 in one window, and something else in the other, then you can range vertical lines, but other lines (diagonal, etc) will be WAY OFF. A good check is a triangle set up with one point up, and the base flat on the ground. When you look through the rangefinder, you will see both parts... now you "range it" and bring the bottom in line with the top. If elevation is correct, then BOTH edges (left and right) of the triangle in one window, will will touch BOTH edges in the other window... the left side will touch the left side, and the right side will touch the right side... it should look kinda like a straight sided hourglass. But if elevation is off... one of the images in the window will be larger than the other, and you can only get one edge to match it's reference side at a time, the other will be off. That is elevation... set it first, before you adjust the range zero. CatShooter. [ 07-27-2002: Message edited by: CatShooter ] [ 07-27-2002: Message edited by: CatShooter ] [/QUOTE]
