Just wondering over what sort of distance one of the diy laser levels
will work? I need to check a level over a couple of hundred feet and
suspect that it wouldn't be powerful enough but assume that I could do
it in stages by laying out some sort of peg system.


Mine will send the little red dot a hundred feet easily if used after dusk.
Don't know how accurate it would be though.


It doesn't have to be hugely accurate so it might do the job.

The cheaper units typically have a divergance of around half a
milliradian. For less divergance, you need to be able to focus onto an
objective, and have a bigger lens.
The cheaper ones will do a spot of maybe 5cm at 100m, and this is
trivial to see at dusk.
