One of the things about most current detector configurations that I don't understand, is the tendency to put a lot of the weight in front of the hand. The White's machines seem to have it right with putting the processor under the arm and the display right above the hand, but why aren't more of the manufacturers following suite? I only see one of the current Minelab configurations set up that way, but the price of that machine will give most of us pause. Also, if you divide up the weight that way you can actually set it up to use 8 AAs or their equivalent and make the LCD display more configurable. In fact, the LCD display should be set up so you can choose what you want displayed to eliminate information overload. With the technology itself seemingly at a standstill, with regards to depth and discrimination capability, the real challenge would be to design an extremely user-friendly, durable, configurable, fast recovery, not overly EMI sensitive, well balanced machine that kept the price point within reach of a lot of users. I see a lot of good things in different machines, but I have yet to see a machine that captured most of those qualities in one machine, but then maybe I'm missing something.
