Ok went back and dropped Normal Disc. to 0 1270 was rock stable with 10 Max Sen., She's still pulling more up but its getting thin, I think when I go back next time I'll use my old 555-D with the 11"coil, she goes super deep and what nice is I you can listen and just hear it break the threshold audio cause you have to have an audio tone all the time, and also when the target is to deep to break audio you wath the needle on the meter fluctuate, even just a tiny hair means there something do there. Also you can use reverse Disc. which is great. No coins today.
