Hello all,
At the recommendation of many on this forum I bought the 5"x10" elliptical searchcoil for the GB Pro yesterday. After a quick fastening it was ready to go and I was on my bike to a location that was good testing grounds. I had detected this area many times before with the 5" round coil to no avail and was hoping the new elliptical coil would change that. The site was along the edge of a seasonal creek and had been subject to extensive ground sluicing by the old miners. Tailings, oriented perpendicular to the creek, were quite shallow and arranged in long narrow lines. Beneath was a thick yellow-white clay which was ubiquitous throughout the area. Manzanita growth was dense, but after a short crawl I came upon a clearing and began...
Except for old rusty nails, which occurred in piles at the ends of the tailings lines, there was very little trash and after about two hours I'd only dug four signals. Since the tip of the elliptical coil tapers to a point, I was able to get between the manzanita more easily than I could with the round coil. Amidst a tight cluster of trunks I hit a good target that set the arc number in the low 40's, the big number below 8, and the ferrous bars to 0. About an inch into the yellow-white clay was the largest piece of gold I've ever found. I had previously missed it simply because I was not able to fit the 5" round coil into such a tight spot.
Since this was my first day with the elliptical coil it's far too early to make any lasting assessments, but I did notice a few differences from the round coil. Other than the obvious weight gain from a larger coil and longer cord, the first was that this coil is more sensitive to being bumped. It quickly became evident that I would have to set the gain lower and keep the coil higher off the ground to avoid false signals from bumps. Another difference was that the ground balance numbers were consistently lower than than those of the round. Furthermore, some of the trash readings on the display were slightly off which led me to dig objects I would have otherwise skipped. With this new coil it's much like learning the detector all over again, but a nice piece of gold is a fine way to start.

That is a chunk for sure.
