Hey all, so I took the Vaquero and another machine I have, the whites eagle spectrum, to a park that has a spot where an old foundation used to be. I didnt know how old it was, but wanted to give it a shot. I used the Vaquero first with the 5.75 concentric and it was still tough to pick up clear signals because of all the trash. I didnt find much with it. When using the eagle spectrum I could tell there were a lot of iron hits that were being DISC'ed out, but I managed to find a Carolus III Spanish reale 6-7 inches down and I think it's dated 1774. I want to use the Vaquero in this spot again because I know it's powerful but I'm not sure if I should use all metal just to dig everything and have great depth, or if I should use the stock coil and not super tune or just try the 5.75 again a different way...I'm not really sure how I should run it in this scenario and would appreciate tips
