11" DD VS 10" Concentric

Tom,

There is a great deal of controversy among new users wrt which of these coils outperforms the other on the F-70/75 in trashy ground, high mineral ground...in terms of target separation, depth experienced, target ID/discrimination.

We know you've covered this in the past at length. I've searched way back through the postings and short of reading every thread, I can't find the information. Could you be persuaded just one more time to spell out this comparison please?

Thus in the future, rather than fruitlessly debate this subject with users, I will refer them to this forum and thread. Thankyou Tom.

Jim.

Maybe this post will help a little.

Thanks Rob, but I did not see the type of information I was looking for at this link. Maybe Tom can provide a recap on this topic.

Jim.

In a nutshell;

The elliptical DD 11" coil is approx 1.5" deeper..... on coin-sized targets (in the dirt)..... over the 9.75" concentric. The DD coil separates adjacent targets better (most all of the time), in most cases...the DD coil will handle bad dirt better. Both coils ID targets with nearly identical resultants. The DD coil 'falses' to a greater extent ... on steel bottle caps; whereas the concentric is less likely to false on these same steel bottle caps.

Thankyou Tom. For future reference this thread will be easy to identify. I fully intend to refer members from other forums to this site, as this topic seems to be a matter of dispute to many newer users of these units.

I appreciate you taking the time to go over "old material" Tom. Thankyou ever so much.

Jim.
