Before purchasing the 12.5" DD Excelerator coil I had been reading the few occasional posts concerning the 14" Excelerator DD coil for the MXT/DFX, and I don't recall noticing if any of the posters mentioned a couple of performance features of the Excelerator coil. For those that may have mentioned what I am about to point out, I do apologize for missing your posts.
I am going to assume for the sake of arguments that the 12.5" and 14" Excelerator perform similar in the field aside from one being slightly larger than the other. I have not used the 14" coil, and only own the 12.5 DD coil. What I have noticed is that the 12.5" DD coil in no way acts like the Minelab coils (for example) as far as true DD performance. What I mean is that there is a sweet spot on the Excelerator coil in the center area that is similar to the White's 5x10 DD coil. The Minelab coils have no sweet spot per se, and pinpointing a target requires a different approach. The Minelab coils give pretty much an equal strength target response from the entire length of the coil with no sweet spot in the center. (At least that's what I have noticed when using a Minelab DD coil.)
I also have noticed that the Excelerator coil has a much wider "windshield washer" signal response from targets that does not allow for precise pinpointing or easy target size analyses. There is no thin line or slim line windshield washer thin area that gives a target response, and it seems to give a wider footprint. The Whites 5x10 DD coil and the Minelab coils, on the other hand, do allow for very precise pinpointing despite a different approach that is utilized for those differing size/shape coils.
What I want to know is this: How many owners of the 14" Excelerator have noticed the two points I have made, or at least has anyone compared the White's 5x10 DD and Minelab DD coils to the Excelerator 14" inch coil to find any performance differences between the two coils? What were your own observations if you did compare them?
Finally, let me say that the 12.5 DD works just fine with no real problems aside from my observations. I was concerned prior to purchase that instability, or a wavering threshold would be encountered, but I have not noticed anything that required me to adjust the MXT differently. It's only my perceptions and approach to detecting that needs adjustment.
