Hi All. I wrote on the forum awhile ago about electronic pinpointers and asked what people thought were the best models out there. I came across an electronic ground-piercing model that has a thin stainless steel 8 inch probe rod on it. It is called the CP-100 Cache probe and I was just wondering if anyone has used it before or know of anyone that has? I really like the uniprobe, and it's the one I'll porbably most likely buy. But I was just wondering about this CP-100 model. It does'nt run in an all-metal mode, as it rejects most iron and bottle caps it said in the ad. So I guess I was wondering if all-metal detecting probes are the top choice, or if a discriminating one like the CP-100 would be a good option also? Thank's guys. Sincerely, Randy
