M6 and 12" on the Beach?

[jspoon]

How deep do you think this setup would go at the beach?

coil from White's provides a little better COVERAGE for beach hunting, or open, plowed fields, and similar-to somewhat improved depth on coils.

It's really better for going after larger-size targets than dinky coins, and I simply like to suggest some comparisons with a 'stock' coil (8"-9

Is the 10x12 SEF coil good at handling bad ground and how is it at seperating trash from good targets? When and under what conditions would a 5" or 6" excellerator coil be most beneficial or would a Whites coil of some sort be better? Any thoughts about cooils for the M6 would be greatly appreciated.
