Learn how to pace off yardages,

Get a tape measure, 50' is a good one, get some chalk, mark zero and 50'. Now what you do is, walk the distance with a good even step, try to keep say distance each step. Once you get use to this its pretty normal. Take that 50' and divide by the number of steps you taken. So lets say your pace is 2.5' per step, ok that means ever 2 steps is 5', ever 12 steps is 30', so every 12 steps is 10 yards. So you hit an iron shot, walk off the distance and do the math. For me, i learned to take a large step that is 3' per step, and i've come close to 50 yards, i think i taken average 49 steps per 50 yards, that's pretty good. So, i can easily pace off yardages. I know, we don't trust the yardage markers. I've googled mapped the yardage markers on the courses i play, there pretty good, so i don't know were people get all out of shape about it. If you have trouble, google map the back of the tee boxes, and other land markers, and just create a small note book, then you can pace of distances better.
