I've never met a Mexican who spoke real Spanish. The speak Mexican as far as I can tell. It's much like the difference in English here and in the UK. They are very similar but not the same. Now back to the subject: I have both types of detectors and I don't pay as much attention to the ID feature as I use to. It's wrong too much! I now have a Minelab and before that a Garrett. The Garrett was more accurate in predicting what the find would be, mainly because it told you the size of the target. I learned to jockey the discrimination knob on my Tesoreo non-ID machine so that I can fairly accurately figure out what I've got under my coil. The thing I miss most is the depth meter on the Tesoro. It could be an inch or it could be 10 inches. The only clue is that it pinpoints louder if it is shallow. But a large target will be loud too, so maybe not? Anyway that's my take. Monty
