I used a Fluke TS100 Numeric TDR as a pulse generator for "gross" detection of items of interest, and a Pico Second Pulse Labs (PPSL) tunnel diode for "fine tuning" on the anomalies.

I suggest that you start with the TS100, they are only a couple of hundred dollars each. I prefer Fluke part number 26500500 with the right angle bed of nails)

Also, the PPSL product I recommend (you need to swap modules based on what you observe with the TS100 and scope):

I have had really good results in just using the TS100 with a high bandwidth scope like the Fluke 199C.
