"o 2 find dosh": Has any body had a bad 10 inch coil.
Yes, I have had or handled a number of the crappy 10" D2 DD coils. I got an early prototype 10" D2 from the factory. It was faulty and I returned and swapped it for another. That one kind of worked, but it wasn't impressive. The 950 Concentric coil was more stable, provided a little better coin-depth, and, as with most Concentric coils, the Discrimination was better and it had a tighter TID/VDI than the 10' D2 Double-D coil. The first 'Vision' was introduced and I got mine the week before the 'official' introduction in Texas. A lot of flaws and issues with the circuitry design ... and the stock 10' D2 DD coil. They did some fixing when I took it in and they swapped out for a brand new 10" DD coil.
It kind of worked. The detector didn't and it was back to the factory to try and resolve more design issues. I'd had it now for about 10 days and this was my 3rd trip down. They replaced the entire detector with a brand new unit out of production, coil and all. I used it the next day, and being frustrated I sold it to someone who just had to have it. But that coil was also used when thee went from the MXT Pro to the MXT All-Pro. The only changes made were adding an 'All' sticker to the sides on the control box decal, and changing to the 10' DD coil. The sign of a bad trend to go more DD coil instead of a Concentric.
At the time I was a White's master dealer and I had several people with an original MXT or MXT Pro who wanted the 10" DD coil. I warned them of my experiences, but I bought about a half-dozen for customers. Half of them liked the coil, half of them didn't like the coil or the coil was faulty and didn't perform well. They were warned and dealt with the factory about the coil issues.. I let some friends check out a brand new 10" D2 DD coil and they all returned it, the same day, telling me it was terrible. I didn't argue with them.
I had some things transpire and I wrapped up 2013 selling off everything, at my cost or less, and got out of being a detector dealer. The bad news was the MXT All-Pro's I sold had some of there 10" D2 DD coils, which were standard coils, that were faulty and they needed to be replaced. The good news was that when they made that change to the 'All' version, they also included the 9" 'spoked' Concentric coil which ended up being a terrific coil. No issues from anyone and those worked well.
"o 2 find dosh": I have been using the 10x6 eclipse and the 6x4 shooter,
Naturally, coil choice has to work in harmony with the detector they are attached to and for certain applications. I have used both the 6X10 DD and 4X6 DD coils, especially the latter size on different models from White's. It was an 'OK' coil for some urban Coin Hunting tasks, but it didn't fare so well when hunting the very dense iron contaminated ghost towns and other sites I mainly hunted. The 6X10 DD was terrible for those sites, and didn't impress me for other applications. I only owned one, but did try others that people had on their detectors when they came to a seminar. The outdoor portion of the seminars let me try them, and demonstrate what they could and couldn't do.
"o 2 find dosh": The vdi is the same on both coils. But the 10 the numbers are different.
What do you mean by the 4X6 DD and 6X10 DD coils having the same VDI but also having different numbers?
"o 2 find dosh": It ground balances spot on ,Any thoughts.
Yes, and I shared them above. I do not own a 10" D2 DD coil, but I have, several times. I didn't like the good vs bad build quality and glitches, I didn't like the weight, and really didn't like the poor in-the-field performance, and I will not, ever, own one in the future. You didn't mention which model you were using your coils on, or for what types of hunting applications you used them for. You also didn't express why you are interested in the 10" D coil. Matter-of-fact, it would be interesting to know why you only name two coils you use and they are both Double-D design, or why you do not have a Concentric coil in-use, or an interest in a Concentric coil , if you are considering getting a new coil. ????
Thus, my curiosity is raised of not only what detector model you are using and the types of hunting you do or plan to do, but also how long have you ben using your detector? How long have you been involved in the metal detecting sport? What other makes and models of detectors, and search coils, have you used in the past?
