I am interested in a G2 for coin hunting. The ad in the June edition of Lost Treasure for the G2 states: "The best multi-purpose unit ever made, Excellent for coins, relics, jewelry and gold nuggets". Should the 19 kHz given the relic side away? Sounds IMHO that with a 5"DD coil it would be a coin killer and best used in fairly clear areas (if there is such a thing). With dual processors the recovery time should be ahead of the pack. I can see the gold side of the Gold bug Pro in the ads but the one I have seen for the G2 points me toward it being a good coin machine as well as relic. Really like a lite weight machine with good depth for coins in a need to go deeper case.
