Got out today for a few hours, no silver, just a bunch of clad. I've been hitting copper pennies at 37-38 on a regular basis which reminds me of using the Ace 250, I would notch out the penny icon to keep from digging zincs all the time. With the Ace, a dime signal would most times be a dime or a copper penny. With the Safari I only dig a few 35-36 signals to keep away from zincs. If I was out hunting cleaner soil I would dig the "Iffy" signals. On another note, used my new Garrett pro pointer today, really good tool, I used the pistol probe prior, I like the way the Garrett "zooms" in as you get closer to target, plus vibrates. I carried both probes today, used the pistol a few times for deep stuff. "Zinc is o.k., Copper is better." Good hunting...
