Good point Bill, so you contacted them too. I also contacted Garrett some time ago(the person said they would pass on my suggestion) to update the Scorpion with Auto-GB(they already have FastTrack technology), but still keep the Manual-GB and have both types of GB's on a new machine. I would also like a 5-15-30 kHz switch if possible, and a easier and better battery(box) changing. Also keep that famous Groundhog circuitry, unless they can find better. The Scorpions Groundhog curcuit has found alot of gold in the past, and works good, among the best prospecting VLF's. I hunted with a very successful prospector who used a Groundhog, it handled bad mineralization well, good depth, and finds very small gold. Also 15 kHz is almost the ideal frequency for gold rings and jewelry. I use to own the Goldhunter(A2B in Australia) in 1986 and then the A3B, but never owned a Scorpion yet, and have been thinking of getting one. Like I said before with the renewed interest in gold, it would be good to update it a bit with more coils. But yes as it is, it is still good.
