Recently got another 1500 (got outta detecting for a few years) with the standard 9.5" coil but have always wondered if I should get a dd coil as well. Its my understanding that the dd is great for "getting deeper in heavy mineralized" soil. Here's the thing. I can run my sensitivity up around 9-10 in my area without much falsing. Would I really benefit much as far as getting more depth from a dd coil? Thanks

More sensitivity actucally can get you less depth in most cases because the detector "sees" more minerals. Like using high beams in the fog. I have a GTI 1500 and don't use it anymore because the Sov GT beats the socks off of it for depth and reporting on a coin or gold ring under a large nail without any masking.
