Anyone have any programs to help find silver coins and possibly gold jewelry in high aluminum trash areas? I have a new detector with 3.2 program and 11" coil. I have rather limited detecting experience Thanks
Good luck with the aluminum - 4 kHz seems especially sensitive to aluminum trash, most notably the cast aluminum bits buried at depth. Are we talking can slaw trash, pulltabs, cast aluminum, etc? The higher frequencies will help separate every target in trashy areas at the slight cost of depth with all other parameters being equal. I would think 8 or 12 kHz would be a good starting point if you are in a trashy area - you get decent depth with either frequency with great separation, but if there's a lot of bottlecaps you'll want to either use higher silencer settings or go to 4 kHz which almost always knocks out the caps - or at least it will make them more recognizable.
I would start with finding the silver first, then you can come back through with lower notch settings. Try this program...I use it for deep silver and deep Wheats along the sidewalks in the neighborhood. Reactivity at "2" will solidly hit a dime at 9 inches while reactivity at "3" will max out at 7.5" (at least in my soil)
4 kHz (which means TX = 3)
Silencer = 0
Reactivity = 2 or 3
Iron Vol = 0
Sens = 88
Notch = 00-60 and 93-99
Audio Response = 3
Overload = 2
90% silver dimes will ID as low as "72" in this program but more likely will register "75-77". Indian cents can ID as low as "55" and occasionally as high as "66" - just depends on the copper content which was variable at the time. Some of the older Wheats ring up true at "61-62" and other newer Wheats will register around 66-72, sometimes as high as "74". A 90% silver half will peg out at "89-90" almost every time. Always allow a little bit of downward -AND- upward VDI migration for desired targets since iron can both decrease and increase the VDI of a non-ferrous target. There are other factors that influence VDI readings of supposedly uniform U.S. coins, but keep this in mind when setting up your notches and breakpoints, if applicable. You can set one tone for copper coins, like from "60-74" and from "75-90" you can use a higher tone to more quickly identify what's under your coil.
I use full tones, but many people like to have tone breakpoints - personal preferences and flexibility are what make the Deus such an outstanding machine! Have fun and HH!
