This week I went back to the field site of a one-room schoolhouse that I hunted last spring. While hunting it last spring it had the remnants of last years corn crop. This time it was in bean stubble that was cut this fall. The rows of stubble were very close together and were sticking up about three inches, which made hunting it quite difficult. Last spring I hunted the outer perimeter of where the school stood and it seemed to be pretty much empty of good targets this time around. Like many schoolhouse sites, the building was knocked down in the 1920's when consolidation doomed these schools. The resulting debris field was loaded with nails and other low conductor targets. Every swing of the coil in this area resulted in a loud "machine gun" array of hits. I tried various Tones and Processes in Discrimination Mode but between the nulling and falseing and the very short swing because of the stubble it seemed like a hopeless cause. Excess loud noise while detecting can soon result in user fatigue so I needed to try another method. I like All Metal Mode over Disc. because it gives a better indication of what's in the ground,so I switched over to Motion All Metal and turned the volume way down to where it was about 20% of full volume. Without the distraction of the loud sound I started to constantly watch the numbers on the screen and stopped to investigate any number that hit 30 or above. Many times on each swing of the coil there were multiple single digit hits but once in a while a higher number hit would be mixed in and these are the targets that I would slow down and investigate, resulting in the various coins and buttons that I found. As a side note I had the FA ( FAST PROCESS ) set on the Disc side before I switched over to All Metal. Fisher Labs say that some of the response characteristics of Disc Mode carry over to All Metal. I know this is true of the Boost Process but I am not sure about FA ( Fast Process) Any thoughts on this ? The 1835 Large cent hit at 83 with single digit numbers on both sides on the same swing of the coil. The 1866 Indian Head hit this way as well with a 67 surrounded by 7 and 9 numbers. The Flying Eagle in the first photo had a reading of 42 with a 6 "nail" reading right next to it. The arrowhead was a nice bonus find on the second day. I wouldn't want to hunt this way every time because the constant monitoring of the screen can become tiring, but for two days this week it worked well enough for me to find targets in heavy trash that I otherwise would not have found.....Thanks for looking

There was an article in Fisher’s Magazine a few years ago about doing what you’re talking about. Trying to find it now…… basically they said run Disc at 6 and in 2H tones, dig anything in the higher tone. If I can fond it I will try and post the link. I’ve not tried it yet but hopefully soon……
Thanks for the input Draco. It has writing on the back but I can't make it out.

Thanks Ronstar.I will read and try to wrap my brain around it. It seems like a good method to get down pat and apply in the field to recover good targets in the trash laden sites.F-75 Metal Detector Performance Review
