If a person is buying a machine primarily for coinshooting, well, the Gold Bug platform products (including G2) don't have the features that most folks associate with USA coinbeeping such as notches, 3 and more tones for discrimination, and visual icons to identify categories. Plus it doesn't have a low operating frequency which most folks associate with more depth on high conductive targets.
However if you're a beep and dig coinshooter who keeps the discrimination level below foil in order to get the jewelry, too (in other words if you approach it more like relic hunting), and especially if you hunt trashy sites, then you might regard the Gold Bug platform products (of which the G2 is one) as superior coinshooters.
To put this "great coin sniffer?" thing into perspective: I used to know a guy who bought several high end machines (including ours) for coinshooting and gave up on them and got rid of them. For some reason his wife decided he deserved one last chance at not being disappointed, and got him a $129 BH Tracker 4 for Christmas. Well, if he didn't go out to the park and try it, he was gonna sleep on the couch, so he went out and beeped. And beeped, and beeped, and came home with a smile on his face. It was the right machine for him for park coinshooting and tot-lotting, over the next several weeks he learned its every sound, he beeped and dug, and cleaned up. He occasionally ran into another beeperist swinging a fancy high end machine, and offered to check their targets for them before they dug. He was right more often than the other guy's visual ID display was, and while he wasn't helping them out he was digging lots more coins and jewelry than they were. Despite his helpfulness he won no friends, ain't it a shame? The 6 inch max depth was an advantage for him: he wasted no time trying to chase deep targets that were more likely to be misidentified (and more likely to result in getting banned from a site), and spent his time cleaning up on the quick-to-diggit shallow stuff.
So there's an example where a low end Bounty Hunter was a better coin machine than any of the $900 on up high-horsepower units. In all probability, he could have done just as well or better with a T2 had he taken the time to learn how to tame it for the shallow stuff and then master it that way, but the T2 doesn't invite that sort of use, it prefers to be run like a racehorse.
This is why I tend to avoid making statements about whether one machine is better than another for USA coinshooting, even if the only machines being considered are ones we make. Everything we manufacture that we represent as being suitable for coinshooting is in fact suitable for coinshooting and has its unofficial fan club.
Relic hunting, gold prospecting, saltwater beach, and cache locating are much more specialized and demanding; therefore it's easier to generalize about various machines' suitability for such applications.
