I received Andy's book last week and have been looking forward to experimenting with some of the ideas in the book. I had the patterns already loaded from page 135 which are very similar to Andy's popular program for the Etrac. I did not have the #2 pattern set up but copied it from the book. I have always thought I should run Ferrous-Coin and that is where I have ran it for the last 3 years. My sensitivity runs about 23 and I run auto +2. I switched to Low-Trash, fast off and deep on. I went to a spot I have hit very hard over the last 4 years. I had searched there for almost 25 years prior to that with no luck. It had been grided in the early eighties by a couple of guys with Deepseekers and cleaned out. They had found about 75 coins then. I bought an Etrac in 2012 and found about a dozen coins. It is an old church yard surrounded by cornfields. The church was removed in 1923. It is still mowed a couple times a year because there is an old fenced in cemetery behind it. I had not found 1 coin with my CTX on this property. I just figured I cleaned it out with the Etrac. I went to a spot that almost all the coins had been found. It is a very small area close to the fence by the cornfield. After about 10 minutes a received a signal that I probably would not have normally dug but I was trying a new program. Ferrous jumped only from 1 through 4 and conductive from about 33 to 46. The round icon was there but jumped around with no color in it. A very week signal but consistent. I dug down and at a full 9" pulled this 1892 Barber dime. Now I cannot say I might not have heard this before but was just curious because of the new program. I searched for another half hour but the heat and mosquitoes drove me away. I would have to say this book gives you some ideas where you normally get set in your ways and think the coins are all gone.
