I've got an XL Pro and I need a large coil that's deep for hunting open fields. I'm wondering if the Blue Max 1500 serve this purpose. I would mainly be hunting for relics and I know this coil will do good on larger items and give me the coverage I need, but I need to get deeper than average on bullets and buttons. My other, more expensive option is a different detector. I would like some opinions from people who have actually used this coil before I peel off the $$$.
