Dad and I got over to an older section of the city at a vacant lot that we've talked about detecting for a long time. According to the old maps, the house built in 1912 but was torn down in the late 1970s and has been a vacant lot ever since, so this small fact tells me that the lot would be zincoln-free...which it was except for three targets. We spent about 3 hours battling the skeeters that didn't want to quit, no matter what we tried - but the good finds made it an enjoyable outing nonetheless! Started out in 4 kHz but EMI was relentless, I tried lowering sensitivity and audio response, which helped somewhat, but I wanted to try and listen for whisper and broken targets on the fringe of detection depth.
First find was a lovely green 1917 S Wheat at about 6" down, it read "56" in 4 kHz - I barely made it out in reactivity 3, silencer 0. EMI was horrible, so I tried reactivity 2, silencer 0 with no difference. Switched to an almost identical 8 kHz program, and reswept the hole where the first Wheat came from and got a persistent tone without VDI. About 2" deeper and a little offset from the first coin came a nice green 1920 Wheat, and this was to set the tone for the rest of the hunt - every old coin except for the V nickel was 6-8" deep and most of the time the VDI was non existent!!!
The 8 kHz program is used is basically the same as the "4K Super" (variant of Coop's bottlecap program), but will hit nickels and mid-conducting coins (Indians, small gold coins, early Wheats, etc) a lot harder and deeper than 4 kHz. The tradeoff is that some aluminum trash also hits harder, but for this site it worked like a charm:
I've been trying Manual GB at "80" rather than the usual "85" and it seems I can hit smaller items a bit deeper with this setting. My soil usually reads between 76 and 82, but rarely any higher. Some deep iron, especially nuts and bolts sound like a clipped coin signal, and I've noticed this since lowering the GB. The detector "sounds" a little sharper on deep targets - so I think moving forward GB is about right.

Dad found a zincoln after the first hour, and some aluminum trash, and his knee was starting to bother him from a previous hunt. He was getting a lot of mid and high-toned targets with the CZ6, but most of them were turning out to be nails and small bits of aluminum trash at depth. I told him about the two Wheats and he found a faint "square pulltab" indication that sounded good both ways not far from there. Around 6" down he pulled a nice 1918 Wheat just as green as the others. I checked this target before he dug and in 8 kHz (7669 Hz) it read "69". This is where some Wheats read in 4 kHz, but it seems the varying tin and zinc content of especially the early pre-1940 coins contain more tin, which would lower the conductivity of the coin but also make it more corrosion-resistant.
It seemed that this place had been hunted pretty well owing to the lack of surface targets. There was some can slaw, which 8 kHz tried to hit a little harder than the 4 kHz program, but if it VDIed less than 40 I wasn't digging it. I switched back to 4 kHz on these targets and IF the audio went to crap - it was almost a sure sign of the dreaded slaw. The front sidewalk of the lot still exists, and I found the majority of the green Wheats about 10 feet from it on both sides. I got a bunch of small peeps and nondescript targets, which very well could be coins living at 10" or more, just out of reach of my settings. Most of the Wheats were desperate but persistent mid-tones, some were hit only one way, and almost all of them had nails and other iron in the same hole. The 1919 Buffalo nickel was a nice surprise from around 7" down, and was a confident hit in 8 kHz, but again, no VDI. A 90 degree sweep resulted in about the same audio, which indicates a greater chance of a round target (coin) to me.
The "Queen of Clad" SBA dollar is the second one in a week - it was very deep, around 8" or so, and sounded exactly like many of the Wheats dug today. One thing about the Deus...When you have a bunch of deep 7-inch plus targets in moderately trashy ground, it gets difficult to tell the good targets from the background blips and boops, but this may be a Full Tones issue rather than the signal processing. I've learned to "just dig it" if it sounds halfway repeatable, but today I crisscrossed some of the front yard several times and found more deep coins on each pass. There were nails and iron whatsits, also some chunks of cast iron mixed in with coins at depth; but the audio was clear enough, although clipped sometimes - for me to investigate further. EMI was a BIG deal today, and overall I am quite pleased with the results despite the interference!
The easiest coin to recover was also the oldest; a very thin 1905 V nickel. Searching in 8 kHz the EMI was a lot better, but at times the chatter would get ridiculous - not sure why! I switched to 12 kHz and things really quieted down, and suddenly a "53-54" target pops up clear as a bell. At this point dad was seated on the front steps of the sidewalk, giving his knee a break. I think he pushed it a little too hard today, but detecting is something both of us love to do despite a little discomfort. Anyway, I was joking about this target being a second buffalo nickel, and at only 3" down out came an orange disc. Saw the "V" on the back and got excited - this is another "first" for me! I've found one other V nickel in my life in a stormdrain not far from where we hunted today, about 20 years ago.
I went back to the 8 kHz program and decided to just tough out the chatter and do the best I could since the sun was going down. I was listening for more of those faint, whisper targets but I had worked away from the sidewalk and was now heading towards the back yard. The trash levels increased here, so I switched to reactivity 3. Wanted to get one more old coin as dad had given up for the day and it was getting hard to see. The last signal of the day was a solid "73" in 8 kHz and sounded about 5" deep. Out came a light green 1936 Wheat - I checked it for the coveted 1936/1936 doubled die, but not today! Will have to get back to that vacant lot - it's apparently been hunted moderately due to the lack of surface coins, but not with anything like the Deus. The backyard awaits...
