Well, I'm really surprised at the results!!! First of all, I've read many "REAL" field test results on a bunch of the machines listed and they seem to disagree with the tests listed here. There are so many variables that have to be considered when claiming to test all of these machines against each other. Any detector expert will tell you that there are many "tweaked" settings (not turn on and go) that need to be understood for each type of machine and this will affect the detection depth quite a bit. No one can possibly be an expert on all the different machines listed and you would need years to master just a few. All detectors need to be "tweaked" for the various types of ground conditions encountered and some machines need the halo effect to work at best depth. Also there are other UK/detecting sites that have had GREATLY different results testing the same type of coins listed for this test. I have had several of the machines listed and can say that in tests I did I received WAY different results too!!! The other thing is power, did all the detectors test and have fresh batteries??? This can make a HUGE difference. Also, I take with a grain of salt any Dealers claimed results in any test conducted like this. The Tesoros IMHO are some of the deepest hard hitting machines around and can keep up with the best of them!!! I have owned MLs and they are real nice machines, but to claim these results over everything else just can't be correct. Thanks and HH
