It's not that hard to acquire one, you have to look around, and not scoff at the price. Do I feel guilty? No, not in the least, Americans sold themselves out a long time ago. I was kind of disappointed in the large coil, but still really love the adjustment lay out,as I was constantly adjusting to get that large coil dialed in. I haven't done a software update, but I may not be able too, Also the warranty will be hard to get, I'm sure. But then again I'll soon be replacing a 3rd. kitchen refrigerator very soon inside of 5 years. It doesn't appear that adjusting TX and reaction make a huge difference. And adjusting sensitivity between 75 and 90 is only improved if you run high TX and fast reaction. Otherwise it doesn't respond to improvement. It's not a deep machine, do not expect more than 8-9" on a undisturbed US dollar I barely hit that at a 51 gb in 7" black dirt. Really pathetic for deep targets.
