I went to a club hunt Sunday for the Silver City club in Mass. It was "silver city" with 800 coins buried I was there to help, take pictures, & make sure some of the younger kids made finds. It also gave me a chance to try the Excel in a competition style setting. I put the Excel disc @ +17. Which basically meant I could run around & "cherry pick" all the silver. The Excel worked perfect for this. I didn't keep anything, I would get a signal & let kids come over & "find" it. I saw mostly Whites units out there But the kids were drawn to the flames on the Excel Here's some pictures....
