Hello fellow mds,just received my first tesoro today,eldorado u-max 9.5/ 10 condition. After years metal detecting never did tesoro enter mind ,till recently, after listening to several saying they switched to tesoro after they tried one.Now Iknow why! Have been reading your posts for months and decided time to check it out. Here in north central oklahoma has been 100+ degrees for 18 days straight now,this older body doesnt do much lately but set in house and think about md. lol. anyhow got new tesoro today and had to go out and test..Was only out for 10 minutes max but dug silver plated brass buckle of some sort,about 6 inches deep. No biggie but I live in a house built in 1910, and have been over the entire place time and time again with my other detectors, 4 great ones. However Iam most impressed with first use of tesoro if only 10 minutes. Am firm believer in manual ground balance and already thinking of selling other machines and getting vaquero to compliment this one. Dont how to post pics ,but you guys will be hearing more from me if it ever cools down a bit.Iam now a tesoro type guy
