Thank you for the reply. A transit will not work for this situation. I do understand the beam will be wider the farther away it goes. I dont care if its 3+ feet wide as long as I can tell were the beam is at distance. I may have been a bit generous in my estimate of 1000 yrds. lets say...
I am interested in building a laser for fun but it will also have a purpose.
Specs for my build:
Will regularly use to point from 200 yards, up to 1000 yards. I will be on the other end of the beam looking for where it contacts the object I am pointing at during day and night.
Smallest...
