Last week I ordered a Sharpshooter for my Fisher F5 and while waiting for it, I saw Juit's youtube with the Core coil on his F5. I was not impressed with his results and was about to re-think my Sharpshooter purchase. In his video, he did not give his settings and for that reason, I did not cancel my order. I got the Sharpshooter in todays's mail and quickly hooked it up and went to my test bed. I have all denominations of both clad and silver buried between 5 and 8 inches. The 11 inch dd coil hit all targets with the 8 inch silver quarter and 7 inch silver dime being a weak, but repeatable signal. My settings: gain 85, disc 10, threshold 0, and 3 tones.
I tried these setting with the Sharpshooter and it hit everything almost identical except for the 8 inch silver quarter and 7 inch silver dime. I tried moving the theshold up to 1 and down to -1 with no improvement. I set the threshold to 0 and increased to gain to 90 and I could get these deeper silvers just like the with the 11 inch dd coil. With most small coils, you can increase the gain, if not max it out, so I am hoping that the places I will be using the F5-Sharpshooter combo, will allow a higher gain. A gain of 85 with the 11 inch dd coil is the max at my spots. I have found about two inches of depth difference when going between 70 and 85. Repeated runs in my test bed confirms this difference.
Again, a test bed provides much more information that air tests. I have found air tests to help with recognizing different coins and metals, but nothing beats targets in the ground for getting the max out of whatever detector you are swinging.
