new coil for the G2 and other similar models.
Yes, I know the intention behind the Gold Bug Pro and G2 model designs, and that Dave J. said they were intended to be used only with the DD coils. My original G2 evaluation made it up to 3930 views and many of the e-mails I have received since I posted it on 10/30 had questions about the use of the concentric coils. I mentioned in it that I used all of the Greek series coils and they worked okay.
For the most part, and due to the detector's design and quick processing and response, there are definitely reasons why I like the 11" and 5" DD coils, however I did okay with the Omega's elliptical 10' concentric. A big talked about function of the G2/Gold Bug pro is the very brisk response and recovery, and that is partly credited to the use of the narrow scan of the Double-D design. The concentric coil design has its strong points as well, such as being better at discriminating and better side-approach coverage when working an area.
The round 8" concentric worked, but since I liked the 10" elliptical concentric on my Omega I did use it more than the 8". It worked OK for me in some of the places where I used it, and I liked the 9¾" long concentric coil because it's about 1½" shorter than the 11+" DD, plus narrower, plus a concentric which handled some trash better. I liked the balance and 'feel' of it better as well.
You might wonder if it is a coil I would use regularly compared with the 5" DD, which is just slightly wider than 4½", and my answer is maybe. I might even use the round 8" concentric, but for working in trashier sites the 5" DD does better, but isn't what I would like to have mounted. Instead, I would rather have a round concentric coil of about an honest 6" diameter size. By comparison with the sub-5" DD on the Omega or Gamma or G2, the White's M6 or MXT are best equipped, in my opinion, with the round 5.3 Eclipse.
This coil measures about 6½" across and has worked a lot better for coin hunting, relic hunting, and even nugget hunting (for me) than their elliptical DD that is about 3"X6½". It is the coil I used about 95% of the time on the M6 and MXT models I've owned and I really wish I had a smaller-size, round, concentric design for the Teknetics models. For me, an ideal size would be 6" in diameter.
On the G2 the Omega's elliptical concentric coil works, for me, but it is still too large for hunting in the trashier locations I like to hunt where a smaller coil is needed. There, a 5" DD will have to do for now and I'll just keep hoping for a slightly larger round concentric coil. If the area is open enough with less trash to use a larger coil, the 11" BiAxial DD can handle the task. Not that I like it a lot better than the Omega's standard coil, but they both can cover more open ground where there is less trash to encounter.
Honestly, I prefer smaller-than-stock coils for most of the hunting I do. If I was seriously working CW type relic sites and wanted a little more coverage and maybe a bit more depth, the new 15" for the F-75 and T2 models
might be an interesting coil to try. I think it might help, but I also wonder just how well a larger coil would do considering the brisk processing of the G2/Gold Bug Pro.
I tried the concentric on a dealer's version 1 Gold Bug SE and they didn't work too well. They worked, but side-by-side with the G2 they didn't work as well. on
MY G2 both concentrics worked. The biggest problem most people have with the Gold Bug Pro and G2 designs is that they need a brisker sweep, and while they give a nice quick response to shallower targets, they do trial off quickly as the target depth increases.
If it is a larger-size target and lower-conductive, they do better. If it is a smaller target and is a high-conductive type, especially, they do get weaker quickly. This is especially noticed with the sub-5" DD and that's one other reason I would like a round concentric coil made to work on the G2/GB Pro and Greek series models.
