I've found the vaquero to be one heck of a jewelry finder for me with 2 silver rings and 4 Junkers park finds (one had what looked to be emeralds going completely around ring. almost swallowed my tongue but it was junk) and I'm only on my 3rd battery!Haven't found any silver coins yet scored 6 wheat's quite a few copper pennies and a lot of clad. Need to invest in a coin tumbler at the rate I'm going. Unfortunately now that spring is in full swing my wife presented me with her "honeydo"list so I'm going to need to compromise in order to get that 3rd battery used up once I get her pet project done next week! Love her to death though.
