There are a couple of "tricks" but basically it just takes practice. You really need to learn what 10 or 20 yards looks like. Then go from there.

Here's a few "tricks" you can use to help though:

- Find the mid way point and judge to that, then double it.

- I find I do best going from me to the target in 10 yard chunks, when you don't have
room for another 10 yard chunk you guess how short you are.

- After some practice you will learn when you can no longer see the target definition with targets like mcKenzie HD, the detail lines are visible until you get x yards away, you just need to find "x" for your eyes.

- You will learn that under some conditions you over/under judge. For me, I ALWAYS under judge in fields.

Takes practice. One thing you can do is to take your range finder, tell the check in table you want to "donate" your scores and ask if you can use it. Everyone in the group will probably need to agree to also donate to do this.
