8” Concentric searchcoil

[Jesse James]

With only having personal experience with 2 machines so far, I sometimes research others on websites to see what they offer, and the different price ranges. But I noticed on the Bounty Hunter website that a majority of the machines come with an 8” Concentric, Open-face waterproof searchcoil. They pretty much all look the same. My question is with all the different price ranges, but mostly the same coils, would the biggest difference be with the screen indicators? If so, how much of a difference would that ultimately make if I dig 99% of my targets anyway?
