Digging deeper with Twinkletoes!
If you feel like digging more and deeper targets than ever before, try this new and exhausting technique. This will work well in an area where oil drums or other large targets like tanker trucks are buried deeper than 17 feet, if the ground isn’t overloaded with too many pre 1964 coins. Turn on VCO/Ratchet Pinpointing set D/C Sensitivity to a fairly low number, like -2 on the +10-+50 scale (Sorry, don't remember the scale on the XLT but it weighs about 6.5 pounds). Now, when you start hunting, click the trigger forward to hunt in the All Metal mode ......you need to set ground balance so you get a faint threshold in the pinpoint mode to get maximum depth. You are going to search for the faint soft signals (not the short choppy ones, these are usually industrial chunks of large machinery and scrap iron). When you get a signal, pull the trigger for normal detecting mode (discriminate) and sweep over target, if it reads at VDI #-95 thru +95, and seems larger than 2 feet across dig it. You'll find that those very deep signals will generally ID at +95, or anywhere else in the number range. Basically what you are doing is hunting backwards......that is hunting for huge pieces of junk and hoping to find masked coins layered above them as you dig. Check the target again in the discriminate mode. This is harder than actually hunting in the normal preset coin mode because you get the maximum volume tone ID ringing in the depth of your ears. To be sure that the target is out of reach sweep very slowly. You can often hear a target response if you sweep very close to or actually under the ground, but not necessarily directly over it.
P.S. Today I did some more experimenting with my XLT using a 95 inch coil and tested it on my 6 foot deep clad dime buried several decades ago. At DC sens of -1a & DC sens of -15a2z, I had no trouble pinpointing, meter read 6 feet deep & DC phase was about -900 on this dime in this severely uneven ground (ugh) DC phase of -90 to +95 or worse, mostly. When I increased my DC sens mDm to 50 or so, the dime read 5.5 feet deep with DC phase in AMm of about -87 and I was having a little trouble losing my balance. I had preamp a six pack at 0600 hours & AC sens didn’t matter to me at this time. Targets seemed closer to each other (wider) at lower DC sens. the beep was about 4 yards wide. I also found out why I used to have problems with the m-damn VDI sensitivity giving me a.m. readings on non-existing objects, because they weren’t nonexistent. They were probably cars buried several feet deeper than I had expected. Apparently, the AC sens preset of 6abc4 was too high for nhb and too low for shallow digging. Now that I have the AC turned down to 58, I can turn the VDI up to 86, no problem for a nhb! I like that as the 6 foot deep dime now produces half to one bar at right instead of half to one bar at left. Right after that I left for the bar.
I can view it from my phone.
