Well to start off, I'd have to say I've been a bit of a hypocrite........................calling for a new Tesoro Target ID unit, but purchasing a Silver U MAX. Started detecting in 1974, and i was there thru the heyday years. Most recently I've owned a Whites M6, and a Garrett AT Pro. But noticed that while my penny/clad collection was growing....................where was the gold rings/jewelry?? Used to find quite a bit of that stuff with my Fisher 1266X. Hold on........that didn't have target id!!!! I kept quite a good record of my finds in log books.So I went back through them...................seems my gold finds fell off when I used a Trget ID detector. So I'd try a cheap experiment. Silver Umax not costly, quite cheap...................buy one try it for a while and see what happens. Well as beginners luck would have it I found two gold rings in the first month!!! But I was digging much more in they way of junk. After 3 months ......one gold earing,3 gold rings and a gold charm. Most of the rings read solid "pull tab" on my target id detectors!!!!!!!!! Too many people used to fancy screens on their cellphones.............would also probably fall into the Target ID trap. It's a great selling feature.............but you miss an awful lot of good oportunities. My experiment continues.........I'll see how things work out in in the next three months. I've set a six month schedule for my experiment...parks soccer/ball fields beaches........a variety of locales will be visited. So far....................I don't miss my target ID!!!!!!!!!!!!!!!!!!!!!
