  1. 3D masking is certainly a real world challenge.   I don't think there is any universal magic combination of settings. The best I have been able to do is learn what actually helps and have an idea of how handicapped I may be on a site.

    Each detectors signal processing is the key, the real source of any magic. Understanding this better helps me do better.

    Interesting thread.

  2. I will suggest that the unmasking difference between the two programs has to do with how the SMF is weighted & processed. Even if you have the same max kHz setting,  the Sensitive program will favor the higher end of the spectrum as opposed to the General program.  Higher frequencies do not normally hit coins as hard but do hit ferrous harder than lower frequencies.  The 2D air test is not hard. The 3D in ground with 5" between  the 2 targets is hard for most any detector, even in mild soil.

    I have experimented a good bit on at depth 3D masking. If ferrous trash, multi frequency is the way to go for sure. The lower weighted mix the better. There is also a sweet spot on reactivity/recovery and careful coil control is needed in interrogating a suspect target. I also find that being able to hear the iron and the higher conductor interact under the coil is helpful. TID will jumpy but not too wild.   Al trash and high mineralization is a whole other ballgame.

    You may want to try using the lowest Max Freq possible on the Beach Sensitive(and General) and play with the Reactivity some more.

    Let us know your results as this applies to all detectors and types of sites.

  3. The hook is unusual in that the nose has an acorn shaped end. I'm sure it was used on a wagon somehow. Kind of big for a trace chain. I wouldn't be surprised if it came from South Carolina after the War with the rest of the family. It is definitely older than the house site.

  4. No Gold or Silver. Only 3 coins. The partial toy soldier is neat and the small Flur de Luis ornament. The plated buckle is stamped brass so maybe from a cap gun rig.

    For some reason the photo loaded upside down. I will try again with 2 more photos. The first showing some of the big Iron. The chain & hook are hand forged, so quite old & worn. The plow share is a common type find for me. This one is whole and cleaned up well. I intend to use it on my push plow in my row garden.  The second photo shows the house with a family reunion gathered together on the front porch about 1927. Fortunately, older relatives who are in the photo as children, helped me get everyone identified.

  5. I am almost positive mine also shows R1.

    Your observations are spot on with the Tarsacci.

    NASA Tom makes a good point on sweep speed but like any detector there is a Goldilocks speed that is just right given the conditions. Too fast OR too slow will lose depth & targets.
