Looking for deep civil war bullets with v3i

TROLL
Im a new v3i user and have been having pretty good luck with it. Im finding deep brass relics and copper coins that ring out with pretty unmistakable tones/vdi which is an improvment from my other machines.:) The only area Im having trouble is with deep (7-9 inches) civil war minnie balls. I tried to use all metal and look for a stronger 7.5 meter but I dug nails and iron. Anyone having luck with these and have any suggestions ? Maybe a setting or different coil like super 12 or 950 coencentric. Im in a civil war camp that has dropped 3 ringers at these depths for sure. My ground probe was -88/2% with no emi
 
I would think that you should not have a problem with that depth especially in your fairly mild ground and in All Metal at that. Have you tried to plant a Minnie at that depth and detect it? I get three ringers at 10" with the Hi Pro program and the VDI is bouncing around at that depth, but I know it is something that I want to dig. If you are getting copper coins at that depth, a big hunk of lead should blow your ears off.
 
My experience with my v3i is this. I have a site that troopers played on back in the 1790-1810 timeframe. I have picked up buttons pretty deep with 22.5 freq being the strongest(low conductors ususally pewter). Bullets the 7.5 freq usually the strongest. If it's deep bullets you're after run 7.5 freq single frequency acceptinging all vdis except +94/+95 and make all tones zero for VDIs -95 thru -7. Find your best performing filter for your ground and sweep speed and run your rx gain as high as practical with a say 90 disc. You can even run tx boost on as well to maybe see a little deeper You can also run 3 frequency best data with the settings above and pick up a button or two but you will be sacrificing a bit of depth on your quest for deep bullets. When you think you've discovered a deep bullet using the settings above try switching to 2.5 single frequency and see if the signal improves. If after digging and you have infact found a bullet you will have a pretty good idea of which freq is hitting the hardest. The old bullets metal composition was not an ideal percentage metal makeup so the 2.5 may in fact be the strongest. A little experimentation may help you decide. Good luck.
 
All very good points squirrel, the three ringers hit hardest in 7.5 for me and the pistol bullets hit hardest in 22.5.
 
Before I started to hunt this site I brought a .58 mini and buried it 8 inches and tried everything I could to get a consistent ID. It would pinpoint hardest at 7.5 and hit hard in all metal but I could not get it to ID out of iron range no matter what recovery, sweep speed, freq., filter(5 band works best here) or setting I used. Using 3 freq all metal I managed to find a 3 ringer at 6-7 inches and it IDed as iron. At this same site I dug a 2 piece eagle button at 6-1/2 on edge that was in the side of my hole using 3 freq/ disc audio and it sounded perfect. At a different site with worse ground I buried a wheat penny at 8 inches and it is bouncy in all frequencies except 2.5 which would nail it, but it would ID as a quarter. The deepest target I dug was a brass ring with the circumference of a dime at 8-1/2 inches with soft 4 way high tone audio.

Larry, are you using the D2 coil when you dig bouncy 10 inch bullets? What tweaks do you make to the Hi Pro program if any?
 
Squirrel pretty much nailed the changes I made to Hi Pro and I use the SEF 10X12 most of the time but it shouldn't make that much of a difference than the D2. I'm just used to that coil from the DFX days and I get slightly more coverage per swing. It sounds like you have so much iron in the ground that you are getting masking and the iron is bringing your VDI readings down by averaging the good target with the iron. Your 2.5 dominate targets are so far removed from the iron that you are getting good readings but the 7.5 dominate targets are that much closer to iron that the VDI's are getting pulled down. If you have access to a smaller DD coil like the 6X10 or SEF 6X8, you might try that which should help isolate the bullets from the iron better. I don't have that problem so I am limited on guesses on how to help, sorry.
 
When I got my first Vision I gravitated to the Hi pro program since I like hearing the deep readings then having the ability to discriminate as well.

I live in Virginia and our soil is for the most part really good so in areas that have low minerals it is no problem to get 12" easy on a Minnie ball and with some practice I have dug dozens at 14" in two of my sites that we have been pounding since 1973

I have not been out detecting but 1 or 2 times in the last year due to back problems but just sent my V3 in for the upgrade and had my coils checked out.

I also hunt in hi transmit power or boost as well. I have used every top end detector for the most part and the V3 is just as deep as the deepest coil for coil and deeper than most.

You will need to crank up your sensitivity and gain as well but EMI and ground conditions determine those settings but if you are getting lower conductors at 7 to 8"+ then there is no reason at all you can't dig bullets at a foot all day long in hi pro.

Jason in TN gave me an all metal program that was really deep as well and you had to use vdi but I dug a 1" x 2" shell fragment measured 16" deep.

All of my bullet digs were measured by digging a big hole and making sure it was in the bottom by taking a stick to dig the last few inches and have it still in the hard dirt.

I also noticed in boost mode I was digging bullets pointing down or up at close to a foot that I know others had missed since it was such a small surface area for the machine to detect. Happy hunting
 
I had some luck using the 5 band and then just the 2.5 freq. The deep bullets would hit in the coins area.
 
For those questionable iron vdi targets...may try to isolate the target....wiggle...just barely moving the coil 1-2 inches...different directions....360 degrees...small coil may help also. Another trick that sometimes works...if target is not next to trash...is to whip the coil(very fast swing)....sometimes will help vdi. Good luck and hope you get it figured out....keep us posted so we all learn something!! gl and hh
 
Get a bigger search coil. :fisher:
 
Get a bigger search coil.
 
In my experience, most minnies are mid-range targets, but occasionally a deeply buried bullet that is pointed up will read into the negative numbers a bit.
 
The bullet I buried is on its side at 8 inches. I can get it to bounce into the mid range/high range a little. I did dig a bullet at 7 inches today that was facing straight down that sounded the same and I also dug a bullet that was 7 inches down on its side that gave mostly consistent high tones. I think my ground minerals just dont want to cooperate to where I can go as deep as others.
 
I miss you sooo much.
