and it is a great option for those who recognize what it was designed to do. Remember, there are no magic wands.
Here are some tidbits that I've posted earlier, regarding the reason I wanted one and how it performs for me.

I plan to get one for two reasons....neither of which have anything to do with any video or marketing information. My two reasons are that it has a smooth bottom and a larger footprint than the 6-inch Minelab coil. Both of which should benefit me in the places I hunt.
(IMHO) based solely on the design, the depth of detection of the new Coiltek coil shouldn't be any less than those realized using the 6-inch Minelab coil. Depending on the actual diameter and winding specifications, it could be more. Likewise, the "left to right" separation characteristics should be equal to the Minelab DD coils. Again, depending on the design characteristics, it may or may not. If it provides TID information (audio and visual) comparable to the Minelab coils, operates with equal stability, detects as deep and separates as well as the 6-inch Minelab coil, I will consider it a good investment for the places I like to detect.

As I mentioned a couple weeks back, the reasons I wanted to get one were two-fold.....a smooth bottom and a larger footprint than the 6-inch Minelab coil. Both of those "reasons" would benefit me in many of the places I like to hunt. (rough terrain, crop stubble and plowed fields).
As to how it hunts....so far, so good. Although it is extremely stable, it is a bit more sensitive than my Minelab coils. I say that because where I typically use Auto +3 on the Minelab coils, I have to back it down to Auto +2 with this coil to minimize chattering. And in wetter soil where I can typically get away with Auto +2, this one had to be backed down to Auto or Auto +1. The depth of detection is a bit more than the 6-inch Minelab coil in that I retrieved targets that were not detected with the 6-inch. As expected, the "left to right" separation characteristics are similar to the other DD coils. This elliptical coil provides quite accurate TID for US coins. The only "con" I've found thus far is one I also have with the Minelab Stock coil. As such, it could well be in the filtration algorithms of the CTX and not the coil itself. Anyway, I've dug several dozen deeply buried, bent, iron nails the past week or so that gave me the solid "dig me" signal from one direction. No matter how many times I circled the target, it always gave me that "dig me" response when swept in a certain direction. Over the years, I've dug enough iron trash to usually feel confident walking past most of those squeakers. But on the other hand, I've found enough old silver coins "on edge" at these sites that I didn't want to pass any of them up. So far, all of these have been those pesky bent nails. Oddly enough, just as find when I dig one of these using the stock coil, the old bent nail is found at the back-left edge of the hole. (about the 7:30 position) With the 6-inch, I can usually tell the difference by comparing the exact target location in Pinpoint, with the exact location in detect mode. But the size of the detection field makes it a bit more difficult with this coil, just as it does with the stock coil. As I said, if it weren't for the fact I've dug quite a few coins on edge in these sites, I'd probably passed up the majority of these "one-way" signals. But they looked enough like old dimes that I wasn't taking any chances. I need to spend more time with the tip of the coil "tracing" the target, to see if I can get a better grip on the location differences.
I had made an earlier post regarding the Coiltek coil and old, bent nails.......

Having more time with the elliptical coil, I have been able to eliminate the vast majority of those pesky old bent nails. The "combination" that I've found to be most effective is the implementation of several tactics. I set Pattern One with some discrimination and Pattern 2 wide open. I like Ferrous/Coin for most sites, with a low tone on the ferrous targets. I typically hunt in discrimination if the trash is abundant. And I hunt with no discrimination if targets are few and far between. As I mentioned in an earlier post, the coil is extremely sensitive. So I set the Auto Sensitivity "one click" lower than with the Minelab coils. And, I set FAST ON. I have been running Fast Off with the Minelab coils, as I felt the processor was "keeping up" just fine. What I've found with using Fast ON with this coil is that the CTX will provide that old familiar "grunt" on the deep nails. It wasn't doing that (in the places I've been hunting) with Fast OFF. With all this in mind, when detect a target in one Pattern, I will confirm the TID in the other. Usually, with FAST ON, if a target "squeaks" in discrimination, it will grunt in non-discrimination. And if I happen to have multiple iron targets under the coil, Pinpoint Sizing will usually separate them for me, with a fairly accurate TID. If, after all that, I am still unsure of the target, I will tip the elliptical coil up on it's nose, and by using the wide open Pattern, trace the exact location. What I've found is, if the target remains in the same location as it seems to be when I sweep with the coil flat, and it doesn't grunt, it is likely something I would want to dig. If, however, tracing the target with the tip of the coil recognizes the target to have moved an inch or so, or if the location is the same and it grunts, it has usually been one of those old nails. Your mileage may vary. JMHO HH Randy
