The new 10" elliptical DD is, in a nutshell, the 5" coil wearing a 10" shoe that is designed primarily for prospecting. It is less affected by ground minerals than the 11" DD and It is less affected by EMI than the 11" DD, but retains the sensitivity and separation of the 5" coil.
It has a huge outward or side foot print that triples the size of the coil around surface iron like poles and such which makes it impractical for use around large iron that protrudes out of the ground or tot lots, etc, but the downward foot print is nice and tight, just like the 5" coil. Supprisingly that large outsized footprint is not affected by ground level surface trash.
In the ground the target id stayed real close to the stock coil, with only occasional differences, mostly due to target centering under the coil. Nickels still read 30 with an ocassional bounce to 31 or 29, Dimes still read as 74 and copper pennies still read 72, quarters still read 84/85.
EMI comparison:
Stock coil - stable with gain at 55, threshold +5
11" DD coil - stable with gain at 60, threshold at -3
new 10"DD coil - stable with gain at 80, threshold at +5, which is quite similar to the 5 incher.
I'll do more coil comparisons later as I have time (time has really been limited this summer).
If you prospect you will need this coil.
If you like to hunt in heavy trash with the 5"incher, you would like this coil.
If you like to hunt small low conductors in open area's in hot ground, you will like this coil.
If you hunt around a lot of protruding, above surface iron you will not like, as in hate this coil. In the ground, ok, above the ground, no - not ok.
The long cord is a topic of conversation and I know it is a personal preference thing, but I like it (been wanting an extension cable for a long time) If you prospect, you like to keep a finger or thumb on the ground balance cause you always like to keep it spot on. It can be tough to do it with the same hand while sweeping but its not so tough if you hip mount and drive the gb with your free hand while sweeping with the other. (If you haven't done it you won't understand). The longer cord gives you that ability.
Also, water hunters have been limited to rod mounting depth. Now you can take the box off and wear it around your neck and get out to at least waist deep water without fear of drowning your box. My take on it anyway.
All in all a good coil for certain applications. I don't see it replacing the 11" DD for coin and relic hunters where depth can be the main objective, nor do I see it replacing the stock coil for tot lotting or homesteads, but for prospecting or hunting in high trash where you would normally use the 5" or jewelry hunting sports fields, or shallow water wading where you can now move the control box off the rod, it will make a useful accessory coil.

By chance, would you have any nugget/flake gold to test with this coil?
thanks
