Question on Teknetics Omega 8000 FREQUENCY SHIFT

[ToddB64]

Greetings

The Omega 8000 is listed as having one frequency of 7.8 kHz, but also has a Frequency Shift feature.

Seems to me that if you can shift to a different frequency, that would qualify the Omega as having more than one frequency.

Can someone explain why the Omega is listed as having only one frequency ? The answer might need to include the technical aspects of how Frequency Shift works.

Does Frequency Shift produce a true alternate frequency or an abberant frequency which cannot be considered a true frequency ??

Thanks,

The nominal operating frequency is 7.8 kHz. The frequency shift feature allows the frequency to be shifted slightly in order to avoid certain types of electromagnetic interference.

Multi-Frequency is typically reserved for machines that operate multiple frequencies concurrently. Frequency shift is using slightly different frequency (say 8.0kHz instead of 7.8 ) but only that frequency. So operation is still single frequency. If you have two Omegas you can shift and not interfere with one another or if there is noise on one you can switch to another and see if it's better. I'm just using that as an example. I have and Omega and used to have a Cibola. The Cibola shifted .3 kHz between the 3 different frequencies. I'm not sure what the specs are on the Omega shift but it's probably very small and similar. I personally would like to know what the three run at since some slight differences may make some iffy targets clearer with a shift. Probably not, but as a tech geek I like to think I have more nerdy things to think about.

Edit: another note, if you do shift, make sure you ground balance again. It will make is off slightly.

Thanks Dave J. and detectingMO !

I knew the purpose for Frequency Shift was to avoid certain types of electromagnetic interference.

detectingMO's reply helped me understand that in order to classify a detector as multi-frequency, all frequencies must be operating simultaneously, whereas if a detector operates with a nominal frequency + Frequency Shift, there is only one frequency operating at a time, i.e. either the nominal frequency or the shifted frequency, therefore it is classified as a single frequency machine.
