I have been lurking and on occasion posting on a Relic Forum. This forum is not brand- specific, that is, nearly all the brands are represented. I have been reading quite a few posts from people using the new Fisher F-75 and they seem to be pulling up some good stuff at respectical depths. A few months ago, I thought I had a good deal on one but it fell through. I'm almost glad I didn't spend the money as work is slowing down...but anyway I got thinking that maybe the success of this new Fisher lies in the operating frequency which is 18 (something) kHz. Hmmmmm, Minelab makes a large 18.75kHz coil for the X-Terra. I just wonder if my machine with the 5x10 HF coil would be just as good as the Fisher? I know you gold prospecting guys use this coil but do any of our coin-getters use it and what do they think of it? There might have been an old post about coin shooting with it but I don't remember.
It seems to me that spending $150 on a coil for a machine that I already have makes more sense than spending $8 - 900 for a different machine that only runs on one frequency. I'm sure that there are other things different about the Fisher, like the ground balance or ground cancelling that might give it the edge. I already have the 6" HF coil and I'm impressed with it and the larger HF coil would be for field hunting. So, I'd like to hear if anyone has much experience with this coil for something other than gold prospecting. Thanks, Ron
