Try a factory reset...
there is way to use the gb without going through the entire process...by using manual, I think.
It has been way to long since U used my 7000-now I have to relearn it...dang, darn and stuff!
They're a great little machine.. I wouldn't trade mine for anything (especially if it was operational at the moment, but that's another story..)
I imagine one would be especially useful to those who like to desert crevice; it can really get into places even the smallest of coils are unable this side of a skinny shaft mod..
Their worst drawback, which I can't call an actual problem, is how they react distance-to-size: The smaller a target's size the closer the Falcon needs to be to elicit a beep -- and also target-size-to-distance-away ratio for detection increases rapidly..
In other words and as an example: It's possible to miss small gold in a two-tiered rock formation at the bottom of a deep crevice a Falcon was able to worm its way between then on to to check out that let's say a Zed would be able to pick up through the entire mass.. But then again you're also comparing an at-one-time nearly $10,000 machine's capabilities against an twobuck-forty-nine$ one-trick-burro's..
However, if yer gonna bust rock n clean out that crevice regardless, a Falcon will tell you if there's gold or not prior to a time-consuming pan-down (which knowing most of us we're still gonna pan down anyhow..) All-in-all not a bad deal for the price difference..
And when it comes to detecting nugglets in known shallow locations or on bedrock that's been placered or naturally swept, a Falcon is simply another of the best -- just with smaller footprints is all..
