Although I do miss the differentiations provided by the Explorer TID, I've found Target Trace on the CTX provides results similar to those we could get with the "bouncing cursor" on the Explorer. I think this was a big improvement over the "flat line ferrous" display on the ETRAC. Add this to Combined audio, and being able to one-click into a second Pattern with minimal discrimination, and it seems to be a pretty decent "substitute" for the lie detector. JMHO HH Randy
