950 Coil verses D2 at the beach question ?

[Tom Slick]

I've read a number of posts saying folks are having better luck as far as their detector being more stable using the 950 coil instead of the standard D2 coil at the beach. I'm a little confused due to the D2 being a double D design, I would think that it should out perform the 950 on a salt water beach, being less susceptable to mineralization. Can someone explain this to me?
Thanks Tom
PS. I've been using my BigFoot from my DFX on my V3 at the beach.

You're right, the D2 should PERFORM better on the beach but I'm not sure it would be more "stable". I don't think the D2 is unstable, it's just a noisier coil and some people will translate that chatter into instability.

I've used the 950 only once for a few hours (not on a beach). I noted it to be a much quieter coil but lacking punch in CA soil.

Maybe that IS the difference. It could be that the D2 is just noisier or chatters more. The 950 being a concentric coil would have better discrimination capabilities so that may make it a quieter coil and less distracting.
Thanks for you input.

Both coils work out on the beach .... where the 950 shines is in its ability not to false when contacting water or wet sand and it is less sensitive to EMI. If one hunts the tide line contact with water is a given. The D2 false's on contact with salt water 90-95% of the time: the 950 only maybe 10-15%. Depth is about the same except the 950 allows you to run hotter settings quieter so the 950 then has the edge.

Why this is true? I have no idea I just know it to be that was from experience.

Jim,
Thanks for the additional info. Maybe the shielding doesn't work as well on the D2.
