I received my 4x6 shooter coil yesterday and did some testing this morning. I was very surprised at the depth I was getting. I tweeked the sensitivity in the coin and jewelry program to RX 11
Discriminate Sensitivity 90 All metal sensitivity 65, TX boost off, Filter 10 High, Three frequencies. I could easily git a strong hit on a dime buried at 7" but what really surprised me was that I could also git a very good reading on a silver half dollar buried a 10", and this is without TX boost. I also tried TX boost on with the same settings as above and got better performance but the probe screen indicated I was loosing 48% of the signal, so I went back to TX boost off. Another thing that surprised me was with a silver dime buried at 9" I could git a half way good signal on the dime. I didnt think that the little coil could achieve this kind of depth, I was very surprised. The only thing I can think of that may have helped with the depth was the heavy rain we received last night. Good luck to all with your V3.
