I use a rangefinder and range different landmarks when I get into the stand.
My dad does not have a rangefinder, he hunts mostly pines and IMO it is extremely difficult to judge distances in a pine plantation. I plan on spray painting different colors for different yardages on the pines early next spring.
His pins are green and red so I will use those colors to indicate the yardage and as an easy reference of which pin to use.
I'm thinking it should work good.
