A very accurate low-tech way of checking level on a tall structure is a plumb
bob.

Subject: [TowerTalk] How to Level a Crank-up?
I want to level my new US Tower HDX-589. I put a 4' carpenter's level on
all three legs of the base section and have levelled them. This is all US
Tower recommends.
Is there anything more I can do? I have heard of using two theodolytes with
it fully extended. But I figure the sections must lean a bit due to the
clearances that allow them to slide past each other. I don't want to tilt
the bottom section to compensate for that lean, since different antenna
loads or wind loads will probably make it lean different directions.
With the bottom section leveled, am I done?
73,
