Nautilaus and ground hawk

[Razr]

Does anyone have knowledge of the Nautilaus and Ground Hawk detectors?
If so are they good all around?

I have used the Nautilaus but not the Ground Hawk. I think of the Nautilaus models as strickly relic detectors and can be used as coin shooters in a pinch. They go crazy at the beach near the wet sand. So I wouldn't call them good alround detectors. They are well made!
