Re: using rangefinders
Keep playing with it and you'll quickly catch on.
During fall mornings in the field actually hunting up to 1200 yards is reasonable (hand held) under the proper conditions.
As the sun moves and shadows change ranges normally drop to where maybe 1K is all that is reliable hand held.
I find tripods a pain even from a 'hide' location. Something to rest it on or against helps.
