Tried out my V3 with the 950 concentric at the same farm site I've mentioned before and I'm still getting a lot of +95, -94 iron hits w/ Jack's correlate program. I guess I'll have to make some adjustments to combat the iron responses?? Interestingly, I ground balanced and ground probed an area that I did for the D2 and was able to get a recommended RX gain of 11-12 vs. 5-6 for the D2. I'm finding in my very short experience that the D2 coil might not be good in my area. Whites has yet to get back with me on why these two different coils can have such a wide discrepancy in Best RX Gains!!!
