I like DD coils in my soil, but my friend loved her 9.5 and she did super. In mild ground the concentric 9.5 is a great coil but as the ground get worse the DD gets better. There is no best coil, it's what's best for you.

Concentric loops like the 5.3 have the following advantages:
Can get good targets under bad targets because of their cone shaped field
They are 10% quieter regarding magnetic interference from power lines
They have 10% better trash discrimination on iron - steel bottle caps and foil
They can shape the target without walking around it
They pin point accurately

Wide Scan Loops (DD) like the 6x10 have the following advantages:
They have better side by side target separation.
They are more sensitive to smaller than coin size targets.
They are more sensitive off the tip area of the coil.
They smooth out the ground reactivity noise by 10%.

Aftermarket loops not specifically made for V3 will struggle a bit, especially at 22.5 kHz, both with gain setting and with VDI accuracy. Even so, I've found the aftermarket loops I've tried -- Bigfoot, SEF, and Sunray -- to be very usable.

The 10DD coil has better ground coverage than the 950. When searching a large area deeper targets may be missed with the 950. You have a full 10 inches of coverage (or close too) with the 10DD at it's maximum depth. When searching (for deep targets) with 950 you are searching with a much smaller conical field and are apt to miss deep targets.

I agree with you Ray, the DD/SEF has much better coverage at depth than a concentric, but the concentric will often have better depth except in the most mineralized ground. It is all a matter of trade offs Elton.

Buy a 950, maybe........ trade your D2 for it, I wouldn't.

Please excuse my ignorance ... Is this "White's 9.5 Eclipse 950 Search Coil 3 - 22.5 kHz Concentric for the V3I that you are referring to?

I prefer the 10" DD for many reasons mentioned above. Depth wise in my soil and test plot the D2 wins. . The 950 is better balanced / weight. I may offer up my 950 for sale.

Yes, this is the V3i forum and Elton was talking about a new coil for his V3i and was considering the 9.5 V rated coil at that time. This thread is 5 years old.
