R.R. You're right about the Whites eliminating ground noise. We work in the Golden Triangle where the ground can be red hot in places. The Whites was the best detector to use in some of those places back then. A Garret Deep Seeker would overload no matter how much you adjusted the settings. In Kingower you can drop a magnet on the ground, and, when picked up, It's totally covered in ironstone pebbles. That's how much iron is in them.I bought a 5900 DI PRO,the same as your one, but when I converted it to hip mount, I found the dial on the handle too cumbersome, so I sold it. Apart from that it was a good machine, as you said. wiley.
