Well, the big 6mm 32" 14k figaro with the cross pendant I found with my f70 in a beach blowout, and it sounded like scrap...The others I got with the Pro...the little 15gr 10k, Tidded in at 37, which I found odd since I was running 40 disc, Iron Off, yet the signal bled through enough to arouse my curiosity to give it a scoop...
Then I got the big Monster 2 1/2 oz of 24k at night in the water...It sounded like a couple of pulltabs or a stainless steel Hose clamp, or foil....complete garbage signal ....I ran into a buddy of mine who runs a Excall II...I tossed it down on the sand, and he was hitting it 8"...so yeah, I happened to be in the right place at the right time on that one....Nobody hunting gold with any rig woulda missed it!
Then the 25gr 14k bracelet?...sounded like a rotten zinc penny or some other scattered trash..big longshore rip going on that day, black sand...in an area I've found all sorts of other decent things, never seen it blown out this deep though, so I was working all signals in a tiny little pocket....Again, it was a matter of being in the right place at the right time....I do trust the Pro...here in the fresh anyway...it hits gold like a freaking train...will NOT miss a ring, and certainly hits a decent sized chain...15gr+ anyways...
