Went back to the old house I'm working and slapped on the 6" and re-hunted some areas in MTC with no luck after 30 min. Switched over to TTF using the relic pattern and went back over some already hunted areas again and picked up a few more. I can honestly say the Merc and the 1919 wheat have had the Ultimate over them several times before and also 1 yr ago with my Tesoro ( approx. 1 ft off walkway to front door). The Merc was only about 4" down but the TTF/6" sniffed thru the iron. Think my problem attempting TTF several times before was trying it in locations with more modern trash. It worked well for me today and should help snag a few more that I'd most likely miss in MTC?...... I think I like it....
