The manual says something different than the detector will show.
I'm glad you solved it .... Locator ... Spectra is an exceptional machine..and I have a lot of detection options ..... in the picture is Spectra VX3 with Taktyk Two-box ...
The Signal probe screen on the Whites Spectra VX3 is the same as on the Spectra V3i .. except for the TX bost function ...
