I used those older Garrett detectors for what seems like forever. Found a lot of good stuff, too. They don't make tones in different pitches like more modern detectors that can sound like bagpipes played by a Piper on methamphetamines. Instead, you listen for the quality of that one tone it does make. If it "blip-blips" it probably isn't a coin unless the coin is very shallow. It could be a ring though. It could also be a pull tab. Dig it and find out. That was always my rule. Broken, scratchy sounds can be a good target at the edge of detection depth. It can also be trash that is almost being discriminated out. You guessed it. Dig it and find out. With experience you will be able to predict what is down there to some degree. You can then ignore the probable trash targets. Or...dig it and find out.
I've come to the conclusion that I'm a dinosaur. I'll soon be eligible for Social Security. My first detector back in the 1970's was a Beat Frequency Oscillator (BFO). As I said, I used other more advanced detectors as they came along. I recently jumped into the 21st Century with a White's DFX detector and, more recently, a Minelab E-trac. Incredible machines with a zillion possible programs and adjustments. With either of them I can tell with pretty good certainty the difference between a real copper penny and a zinc. I'm still left wondering if the target under the coil is a thin gold ring or a pull tab. I....dig it and find out.
