[QUOTE="Guest, post: 227411"] I've been out in the shed making pvc fitments for my detector shaft today. Just back inside having a fiddle. The wheeled thing(for my BFO) is 1161 uH- but it does work on the Sniffer. Likewise the small BFO coil. And the 3 PI coils I've made (so far) all work on the BFO as well. This opens a whole scope of mix'n'match versatility for me. Not sure if any of the high inductance BFO coils will work on the Surf yet though-probably, as it also has adjustable delay/thresh/sense. Down the track I may reduce the R on the volume of the Surf, but for now I am using the [volume controlled] headphones I fitted a mono plug to yesterday, and it screams through them. The Sniffer I have worked out on the bench- despite having 7 knobs- most settings on zero (some are reverse wired so zero is max) noise-sens-grnd-gain. Tune for manual tuning, and [reversed] thresh full up for manual, but reducing for max sens when on auto. Neither of these are gold beasties though, so it looks like the hunt continues there. I have a Tesla-style 6 inch coil wound from cat5 networking cable with the glue drying that may-or may not- give me the sensitivity I desire. [/QUOTE]
