There is 2 Whites detector that impresses me more than any other Whites. They are the IDX Pro for those that dont want to spend the money for a MXT and the other one is the MXT. The MXT has a little learning curve like your Prizm has,but will do much more.
I got a IDX Pro for my wife to use and I tried it too and was impressed at what this detector could do, then I heard so much about the MXT and even got a E Mail from one of the guy that was doing the feild test. After I read his test i knew I had to try one, so I ordered in one and was very impressed at the depth and the IDing of this detector and said it will probably be Whites best seller which i feel it is as it is more of a turn on and go detector with the power of the more expensive detectors that anyone can run.
The MXT is my wife main detector now and she has beat my oldest US dime as mine was a 1842 and now she has a 1840 that she got at 9 inches with the 6X10 DD coil. She also has got one of the only large cents found up here in ND too with her MXT.
What will convince you more will be the finds you will find with the MXT.
