I guess this must be a stupid question because I asked it on the Tesoro forum and got no help so I will ask here. I have a Minelab xterra 70 I had to send it in for repair, no big deal xcept I had to borrow a machine and I hate to borrow anything. Someone offered a machine and I reluctantly borrowed it, a co worker then let me borrow his Tesoro Sidewinder umax.I have never used a tesoro so I asked him if it was multi tone and he just gave me a "you must be kidding" look. I hunt at night and just want a tesoro detector as a back up that has multi tones, no TID. I have heard great things about this brand and thought I would like to try one. So why is this such a dumb question? I am new to the hobby, I am on my 4th set of batteries on my machine, I once owned a Whites years ago and had some fun and decided to try the hobby again.I even went to the Tesoro web site and could not find mention of more than one tone at least on the machines I read about.
