Hi all,
Sweep the blue thing too.
Only issue to me is weight. It stops me to put a larger coil on it.
The iffy signals are indeed proof of an existing, very deep target. the depth being in relation with it's conductivity/shape.
I recently found a 22 ct pendant this way. It was 5 to 6" deep.
I also use a Sovereign GT, depending on the parts of the beach I hunt. The GT in stock configuration is deeper than the Quattro, but the Q finds smaller gold.
If I ever sold my quattro, the reason would be too heavy for me old bones.
