As set by the factory my Golden would drop a tone on deeper coins. A dime at 5 inches in the ground gave a high tone, at 6 inches a mix of the two highest tones and from 6 inches to it's depth limit of a tad less than 7 inches on a dime only the second highest tone. Copper pennies and quarters would do the same but they were a little deeper before the tone changed. However, the tone range can be adjusted with an internal pot so the Golden will hold a tone deeper, at least mine can. I adjusted it to where a zinc penny on top of the ground gives a mix of the two highest tones, which resulted in copper pennies, dimes and higher coins holding the high tone until right at the Goldens depth limit before giving a mix of the two highest tones. It also resulted in nickels giving a mixed tone, but it doesn't drop a full tone on deeper coins like it did. My ground is basically mineral free though and the results might, and probably will, be different elsewhere, but with a 7 inch Shadow X2 coil on the Golden it will get dimes at 6 inches with a high tone, 6.5 inches to maybe 7 with a mixed tone, and a quarter at 8 inches or a tad more before giving a mixed tone. That's with the all metal mode threshold set to a just audible level, the disc set tight on nickels, tabs notched out and ground balanced to my ground with the internal GB pot. I had two Golden Sabre II's back in the 1990's and liked using them, but the Golden goes a couple of inches deeper and even an old arthritic geriatric like me can swing it for a long time before getting too tired to use it. Photos are of recent Golden finds. They ranged in depth from a couple of inches for the sterling ring to 8 inches for one of the wheaties and one of the silver quarters and a little deeper for the heart shaped thing with New Orleans on it.
