To me the elliptical is not a deep coil. Works good if all targets are shallow or in between trees and such. It would be great for real tiny stuff but I rarely use it. I have the hf round which is good for relics and in tight spots. I got the x35 11 and 13 and like them too but mostly rely on the 13” to cover ground faster. They will tell you it’s for fields but as long as it’s not real trashy I think it’s fine. I don’t think I miss much with the 13”. If I am missing a coin every so often it’s likely offset by the fact that I’m covering more ground on every hunt. 3 of us hit a site that has been murdered in the past.... 2 of us using the 13” and one using the hf9”. I think the 13” coils did better. Relics were found deep that had been missed by likely dozens of previous hunters. I found some deep bullets and an Indian. I’m no expert but have been trying to learn my machine better. Disc and reactivity are said to effect depth so the lower those numbers the deeper. I’m sure there are trade offs to doing so but I don’t do to shabby.
