Just not true at all...sick of hearing this mentality. Next someone will tell me that old green screen mac computer will do everything my smartphone can. I have compared wild signals my mx sport and nox 800 to many machines. at gold and pro, tesero, old minelab Excalibur(I think that's the 28 frequency one right?), and so on. Some machines simply can't see some the targets others can, even playing around with settings. Now this could be from many things including frequency used on machine ground mineralization and so on. My 800 found stuff the sport couldn't see, the sport found silver the tesero and the excal couldn't reach down far enough to, the excal is also slow as molasses, and the 800 was finding stuff in the trash it just had no chance of dealing with. excel killed the tesero and at gold in finding silver, and so on. Point is that it does matter what you are swinging depending on what you are hunting, and there are features on the new machines that the old ones simply don't have and will never outperform in certain situations. Recovery speed alone proves this a false statement.
