The advantage of the 800 over the 600 is that the 800 can use the 20Khz and 40Khz as single frequencies. The 600 only uses those high frequencies in Multi frequency, in a still unknown weighted mix. That mix changes depending on which mode you choose. The 600 doesn't have the gold modes, but, in Field 2 you should still be able to find a fairly small gold item. Maybe not tiny nuggets that the 800 can find, but, small jewelry should still be findable.
