Ok thanks for that. I run in the highest manual setting available so I assume that would be max gain/least smoothing. Outside of auto- which I haven't bothered with as yet. Nor have I tried the 14DD.
Interesting observations posted here for sure.
I had a 7000 for 18 months and loved it-thought it was terrific.
I've since bought a 6000 and have just been going back over the same ground and getting plenty of small bits that the zed with the standard coil couldn't get. I always ran the zed...
