I would guess that, just like any other BBS or FBS Minelab, it's probably not going to be as sensitive to fine gold like small earrings or necklaces compared to some other brands. On the other hand, when it comes to a gold ring, and even a very thin gold ring, Minelabs will get these deeper than any other VLF detector I know of on the market. It all depends on your strategy. To me, the most common item lost in the water or at the beach is a gold ring and not a neckless or an earring, so the ring is what I want the most depth on. Being round and intact, mimicking a coin, a Minelab will get a ring (even a thin ring) at greater depths then any other VLF detector I am aware of. There are one or two new VLF machines just coming to market that make great claims about incredible depths. However, this hasn't been proven to me by an unbiased enough source, and they have very limited discrimination abilities and other drawbacks that make them almost useless for anything other than beach or crop field hunting...If indeed they do prove to have the depths that are being claimed. No VDI, no tone alerts, no modulated audio (for telling how deep the target is), instability anywhere near an EMI source, inability to handle salt water, and so on. I must see MUCH more proof from these up coming machines before I'll give an ounce of credibility to them.
