Hello, every one. Is there any technique Can help the DiNi level to measure longer distance under strong sun light?
I usually pace about 60m for each lag, but the sun light in summer season is really a problem for the level, the level sometimes can measure for only about 30-40m away when the sun is strong.
I heart some old surveyor said they used to bring a umbrella out in the old days. use umbrella to shade the level or the rod is it really helps?
