Just started using my e-trac and I am detecting in an old amusement park that is in a rather wet flood plain. Does anyone have any suggestions on how I should set up my machine. The first day I used the coin program that came with the detector and found one buffalo nickel. The 2nd day I used Andy Sabisch's pattern, that I found on Youtube, and got skunked...I am sure it was my inexperience rather than the program. When I dig more than a few inches the hole fills with water.
