I think many of the new machines just have too many tones and not a fan on how the discriminate when compared to the Tesoros. I try not to listen to the target ranges I don't want to dig. As nice as the Legend is and the Nox I have a difficult time hearing the size of a target, audio seems to sound bigger than the target is. I had same issue with the Orx, the recovery speed would never really be spot on to the target. I can see why people dig a lot of cans with those machines.
Just not my style of hunting I guess.
