JM,
It funny that you mention the norton bomb site, I used two
of them mounted on my longline pavement sriper when I worked
for CDOT I would use the x for lining up on the existing line
and use the +1,+2,-1,-2 etc for leading into curves The best
system in my opinion .a lot of drivers can't ever adapt to using it . The end up using a a pointer with a wheel in front of the paint machine. Parts and such are getting hard to find I bought one of the last complete units in existence after searching for
it for a couple of months.
