Anyone using the Pythagoras method.
Something about about Squaws and Hippopotamus Hides?
Two balls and hole make
Careful!

Draw imaginary line between the two balls (the base line) and walk along it looking at the hole - with another imaginary line drawn between yourself and the hole.
Move along the base line until the angles between the two imaginary lines is a right angle - as best as you can judge obviously. When it is look at each ball in turn. Whichever looks furthest from you is first away.
I use a slightly different Geometric method - equally convoluted to explain - occasionally.
