Any tips on these?

Looking at a Amprobe 2004, 2005, and the 4005
AT's..

Any input on these and any others?

Need to trace 0-480V in walls and underground a max of 4'..

I have the Ideal 61-954 "SureTest Circuit Tracer" Kit and it has worked well for me for tracing wires in walls. I have not had the opportunity to use it to trace underground, though I expect it would work well there as well.
