[TowerTalk] Laying out antennas

[Tom Rauch]

Are there any reasonably priced devices for laying out wire 
antennas or tower and guy lines, so the direction heading is 
accurate? What I'm interested in is something that uses magnetic 
north or maybe even GPS to get precise direction references, like a 
surveyor might use. 

Any idea what they are called, what they cost, and where they are 
sold?
