I just finished a morning of detecting with my Cortes and stopped by a friends house to have a beer and shoot the bull. Another friend stopped by and I started talking detecting to the two of them. I asked my friend to call his neighbor and ask her if I could quickly detect her back yard and give them a quick look at my Cortes in action. The lady next door granted permission and we wandered over to her back yard. I did not bother to bring the headphones, but opted to let them listen to all the sounds. Now for the unbelievable. I turned the Cortes on and went less than five feet and got a 95 number showing silver at 9 inches. Repeated the signal from all directions. With my two buddies intently watching, I dug down 8 inches and the target was still in the ground. I pulled out my Garrett Pro pointer and it signaled dead in the center of the hole. I reached down with my hand and scooped out the loose dirt and saw a big glint of silver. I told them it was a flattened out screw cap, but as I held it, it was too heavy. Wiped the dirt off and it was big silver. A 1954 Franklin half in great shape!I think these two are on the internet looking for a Cortes as we speak. Two people who wanted to see how or if a detector works and they witnessed this in the first 10 seconds of ever seeing a detector in action. I did tell them that this was not an everyday occurance.
