What Is The Optimum Axiom Coil For Larger Deep Targets?
I'd like to focus on searching for 1-3 oz (2-4 square inches) or larger size targets that are deeper, perhaps more than one foot down. The ground I'm searching is moderately mineralized and easily handled by the 11x7" mono. I currently have the 13x11" DD and the 11x7" mono. Would the 16x14" mono be a significant improvement in depth for larger targets? I understand the differences between the DD and mono coils, but I don't fully understand their differences in detection depth, especially on
Depth gains are real but not dramatic unless the coil size difference is dramatic, as measured in square inches of coil size. This article below pretty much says it all. In your case if talking multi ounce nuggets, the 16" mono would be the way to go for now, until other larger options appear. But the gain will be a few inches at most, not double or some such thing.
For every target there is an optimum coil size, and going to a larger or smaller coil than that optimum will get you less dep
