Hands Down the best method is the triple Method. I started using this method after reading it from a Peterson's Bowhunting article about the method. It has increased my yardage estimating abilities greatly. 1) Judge the distance in increments. This method requires judging 10 yrds (relatively easy) then double that distance and triple and so on. Once you get close to the target you will need to call it as you see it. Say you get to 30 and there is a distance left. Looks like 3 yards. Go with that. 2)The next step is to judge the actual distance to the target. This just simply requires looking at the target and "guestimating" the distance. Say for an example 35. 3) Next step requires judging the distance to the half way point. Simply look at the target and decide where you think the half way point is and judge that distance. This will be closer and easier to judge. For example 18. Next double that distance (36). ****The last step is to add up these yardages and average them. Now this isn't always easy without a calculator and only a 2 minute time limit, but you get used to it and get good. Our examples were 33, 35, 36 This equals 104 which equals a 34 2/3 yard average so go with 35. Again this may not work for everybody but When I found it in that article and started using it my scores increased.
