Ha ha..
I didn't say "twice as deep" anything Fella. And I didn't imply it either, you did.
And neither did I say twice as quick either. I own two BMW's and I know better than that.
I also own an Alfa Romeo Roadster, and I wouldn't say that about it either.
Even a Bugatti Veyron isn't twice as fast as a 1974 BMW 2002, but I wasn't talking about Veyrons.
I also didn't say "twice as good on the disc" either, you did.
Again, I didn't say "twice" anything.
Cadet tractors cut grass with a preset depth setting, metal detectors can't preset their depth potential, it's impossible.
I think you confused my post with someone else's, but that's ok, we all make a mistake now and then, I do too. Still, the F70, F75, and T2 out do the CZ3D, CZ5, the CZ6, CZ7, my CZ70, the Tejon, and the Vaquero in every way, even on battery life, they were designed to. It was all done intentionally by First Texas for improved top-of-the-line detector performance. Try getting 15-17" on a dime with a CZ3D or Tejon in mild dirt, it's impossible. There is not enough radiation power to start with, but you sometimes can with an F75, F70, or T2. And if you ever get your hands on one and make the real-life comparisons too like I did, you can see it for yourself.. I hope this clears it up a bit..
