Handheld EDM, Rangefinder, etc
A side note
The Engineer who had a Survey License that I worked for in the early 80s wanted to buy one of these types of range finders to use with a Berger transit instead of an actual Total Station.
We had over 10 miles of Meander Boundary to locate around a 255 acre lake.
I rented a Topcon TS and we finished the project within 3 weeks and I had to supply the canoe to work out of.
