have tones or single tone while in the all metal mode?? Ive read several pages here and cant find the answer. No manual to download either.
Thanks,

Hi John,

All metal is single tone only with 4 settings to change the pitch of the tone to best suit your hearing.

Thanks for that reply. One other thing if you dont mind. On the threshold/sensitivity knob, could you explain to me how this works. Something about the sensitivity is 1 to 70 or somewhere thereabouts and then the threshold works after 70? Im a bit confused on this, does this mean it is pretty much a silent search if you have to hunt with your sensitivity below 70??
Thanks
John

Bowie,

In disc mode it is silent search regardless of setting. Technically speaking Gain increases all signals and threshold adjusts the strength of the signal that is reported. Settings above 70 incremetally allow weaker signals to be heard. I don't have a lot of hours on the Omega but it seems to me that above 70 there is some increase in gain as well. I find that the higher settings don't neccessarily boost the loudness of signals or at least the Omega retains it's modulated audio characteristics on deeper targets which makes it seem that way to me.

While I like to make use of the higher settings whenever possible, you still get very good depth and response to coin size targets at lower settings.

The new Fisher website is now up and includes some great information from the engineering department. The report on "process" modes is a good read as well.
