How good is the TDR?

Hi guys,

I had an open circuit appear in a run of LMR coax burried underground of over 200 feet. Using
the AIM I was able to dig down and locate it, within a foot of what the AIM calculated.
It looks like a gopher went thru the conduit and thru part of the coax!

Don't forget the optional protective case for your AIM UHF analyzer.
The case uses a water-jet custom cut high density foam insert in a sturdy black molded locking shell. There are cutouts for your calibration loads and adapters as well as the Power Supply and the USB cable.
