      Unfortunately a transit requires a moderate learning curve and money 
for rental. TIA-222 specs say that you can be out three inches in 100 feet 
and you can eyeball it that close. While I've used a bubble level many times, 
if you can get ahold of an electronic level (good to a tenth of a degree!) or 
a level for dish installations (1/4 degrees) - use it to plumb the bottom 
section. Then you can sight up the face and plumb the rest of the tower 
visually; it'll be pretty darned close. Or use  the aforementioned levels to 
plumb each set of guys. Either way is good enough for me.
