I got the v3 back. Its now a V3i. I was hoping to see lots of improvement. My question is this. Should i be able to use coin Jewry program, factory settings and find the coins that i buried in my yard to practice with the dfx. I know where these coins are and know what depth they are at. Done this when I got the dfx so I could practice a couple yrs ago. I have no problem with my mine lab hitting and locking on with factory settings. My v3 only hits on the .25 cent. Now i know that you can tweak the v3, but clean yard and buried coins with location known. I would think the v3 should hit really hard right out of box with the factory settings. Just so we all know I sent the coil in and had it tested along with the v3. It tested good as did the v3. My coins are buried 4 to 5 inch. I really need to hook up with someone here in south central Indiana that haves one and go do some detecting. Any help for an old man? ( not that old ) Looks like i need it bad.
