5 Deep Indian Heads Show Low Numbers

[miserman]

Today I hunted a rural church grove with the F75 in Motion All Metal. After searching for about an hour with no decent high tones in was obvious the area had been hunted quite a bit. I decided to start digging the low number targets that were in the 50's. With Sensitivity set at 87 and frequent Fast Grab Ground Balancing I started finding deep Indian Heads and Wheat Cents that were 9-10 inches. The numbers were very bouncy and were hitting between 54 and 63 after several swings with the coil. Sometimes the numbers would even drop off into the 30's and 40's with the 50's mixed in. The signals were not very loud and were somewhat broken. While pin pointing, the depth reading was a good indication that the signal was a deep coin. Digging any 50-60 signal that showed depth of 3-6 inches was always trash. One of the Wheats was a 1910-S semi-key date. The Mercury Dime was a very quiet 71 reading and was about 7 inches. With only one silver coin found in the site, I think the area has been hunted to the point that only the deep "iffy" targets are going to produce coins. The low numbers that produced coins today is a clue that solid signals and "good" readings drop off with depth....Thanks for looking

Great digs!

you are seeing a lot of Cu2O, Cu2O3 and not base metal-- which drops the i.d. numbers. Add in ground mineral and just going by TID numbers
and a lot of stuff is left (and this is before other targets in proximity are added in.)
Turn it into a beep, and DIG.

Good information on how deep targets are in a whole new class by themselves. One other note about deep coins is they will have that faint sound and the confidence scale will show low.
Those old coins are getting deeper and deeper each year that pasts so this information is great, thanks miserman.

You sure got my attention with this A M motion hunting, using low ID numbers and the depth.

There is no recovery lag from targets close together and its Much More powerful.
Now the the best thing about Stat: it identifies iron best of all modes (by TID). Iron that fools motion (bottlecaps) will stick out like a skunk at a poodle show.
Scan side/side and watch the numbers. Then scan north/ south, south/north rapidly several times. Conductive target's numbers will not change scanned north/south from side/side.
Bottlecaps//iron will slew the numbers from high 80's/90's to single digits and into negatives.
Every time!

You're right about the faint sound and confidence scale "still looking 52." The one thing I did notice about the confidence is that on a target that bounced around from 54 to 63 it stayed low on every coil swing,but when it did happen to bounce to the highest reading of about 63 it would jump up to 4-5 bars on that one particular pass of the coil. I don't rely on confidence readings that much but it is another tool that helps to give a information about the target.

Thanks for the information "vlad". I will try the Static Mode more often. I was wondering if you have trouble with the audio threshold drifting quite a bit when you are hunting with it. This usually happens when I try the Static Mode. I do understand it can be "retuned" by pulling the pinpoint trigger. I guess I haven't used it enough to get familiar with it.

.raise the loop and pull the trigger is........2 seconds?

Be interesting if you could pin down the anomalous sweep (and more accurate i.d.) and why more target saturation occurs.
