what is the best coil to use on the beach with the xterra 70

[mitwes56]

I have finally acquired the xterra 70 with the factory spider coil and the elliptical 18.75 dd and also the 10.5 dd 7.5khz coil. I just got my new sandscoop so I am set for some beach hunting but I am curious as to which coil would be the most productive on a dry to damp sand beach. I am not a water hunter at all.

I asked "Barnacle Bill that same question about 2 weeks ago but my situation may be a little different than yours because I hunt a very large freshwater beach and he suggested the 5x10 eliptical hf, I see you have one but if you plan to hunt a saltwater beach that answer may change.

1. Take both DD's.
2. GB each over the damp sand in beach GB mode.
3. Increase the sensitivity till it becomes unstable, back off to stable setting. Make note of Sens setting number.
4. Do same exercise with other coil.
5. Whatever coil allows the highest the Sens is the coil to use.

Every beach is different!

The round 10.5 dd 7.5khz coil will go deeper than the 5x10 18.75khz elliptical dd.

I heard that the round 10.5 dd 18.75khz is the best beach coil because more sensitive to gold jewelry but the 7.5khz will work fine.

Empirical data trumps assumptions.. The premise that a larger DD in all locations will outperform a smaller does not always prove out. In this previous post of mine I show where the small 6 inch DD far outperformed the elliptical. And I expect it would have trumped either of the 10.5's. Why? Because in a saltwater + black sand matrix the small coil sees less ground and the sensitivity can be run higher.

This is why I suggested testing each coil at the site.

Seal the elliptical so you don't get water in it.
