Changing frequencies on the F75

[ziphius]

This might be old hat to some, but may be useful to those with less experience on this unit. I was detecting an area and wandered towards some power lines and began getting ZZZZZZIPPPPPP ZZZZZZIIIIPPPPPP interference. I remembered that I had the option to change operating frequencies on this machine (hold menu button and push and/or pull toggle switch). Worked like a charm, interference was eliminated. Later on, I found a deep (7 inches) high conductor target and decided to experiment with frequency changes before digging it. All 7 frequencies could pick up the target, though the F1 and F2 options gave the clearest signals. Some frequencies (F5 for example) resulted in such a degraded signal that the likelihood of walking right past that target in that operating frequency was much higher. Target turned out to be a wheat penny. I'm gonna experiment some more over other deep targets (especially probable silver targets) with this frequency shift and will report back. Happy hunting everyone. - Jim

Good post Z!

The F75 does report through the noise but I never changed frequencies to see if one was better than another.

Thanks for the tip.

just in case you're cycling through the frequencies out in the field and want to reset your machine to the factory frequency.

Ziphius, I think you may be onto something. I recently saw on an Australian nugget forum that two Gpx 4500's were running identical coils and settings except for the frequency. One could hear the target and the other could not until tuned tuned to the other detectors frequency.
