I asked Randy moderator on the CTX Forum and tester for Minelab products this question and here was his reply.
Reset Option
The Reset operation resets the Sensitivity to Auto, NC channel 6, and Threshold pitch to 15. These are all factory preset levels. It also resets to the factory preset User mode, which includes Volume Gain of 24, Audio Response Normal, Multiple audio tones, Conductivity audio, Variability of 25, Tone ID Limit of 30, Recovery Deep OFF, Recovery Fast OFF, Trash Density Low and Ground Difficult. It does nothing to "stabilize" the processor. The Master Reset might improve the stability, if someone had totally boggled up there settings and needed to get back to a fresh start. (yep, I've done that!) However, I see no reason to have to do any reset when you change coils. At least not with a coil that is working properly. I have used CoilTek, SunRay, DeTech and Minelab coils and have never found it necessary to Reset when changing back and forth. I always run an Auto NC when I start up the detector. Even if hunting in the same spot, with the same coil, after taking a break in the action. And I'll occassionally run the Auto NC if I see the Sensitivity dropping down suddenly, or hear the detector chatter. Especially if the falsing has a rhythm to it. (like the harmonics from RFI or EMF) But I've never ran a Reset due to changing coils. Hope this helps. HH Randy
