My knees
gave way when I saw the price.
Learned distance in my younger 3D days when bows were a lot slower. And the drop of the arrow in feet was a lot greater. Had to learn without a angefinder. Practiced distance while on hikes. Another bad habit of mine-walking.
Still use the old arm for 20 yarders. Sure broke up the long hikes. Even have a straight away for judging 100 and 200 yarders.
Guess there's not many old timers before electronics took over hunting. Except for practice, didn't spend two dimes for rangefinding.
