Found the buffalo and silver nickel at a park on Sunday, using the stock coil, two tone mode, gain set at 80 and filters at 20. the 1779 Spanish 1/2 reale came from a different park that also was the site of a colonial home site. My OOR coil finally came on Monday so I had to try it out. Very impressive coil the 1/2 reale was a solid five inches deep with a great signal. I was hunting in three tone, gain at 75 and filters at 20. The area where the home site was is loaded with square nails and other bits and pieces of iron.
