Today i did some testing with the ORX and the HF 9" coil in 13.3 KHZ on an 8" dime a 6" dime and a 7" penny in ground , and experimented and kept changing things and observing and found i got the best hit on the targets at coin fast with a reaction of 2.5, and 13.3 KHZ 80 gain, the 80 gain was because higher in this mineralized sand chokes the signal well after all that testing i got up to the hill of many nails and started swinging, i dug several flat irons and cut nails , but then i got a nice two way signal and dug down a solid 7" and up comes a VF 1882 indian head penny . the soil hear is kind to copper but i was just thrilled the ORX really came thru even as a coin hunter in fact this is the 1st coin off this hill with any detector
