[QUOTE="stevewilko, post: 475263, member: 8651"] I am wondering why my GPX 4800 via the Auto Tune function always selects a channel in the 195 to 210 range. Always... The minelab auto factory tune preset is channel 128. I have paid attention to detectorists' considering the use of a channel between 80 - 120, and I believe this is accredited to a midway point between low and high frequencies. The manual reads; "Manual Tuning through the full range is time consuming.We recommend that you use the Manual Tune for fine adjustments after performing an Auto Tune (p. 32)". So I do the knob winding knob turning exercise trying to find and remember a quieter channel! No, I have been selecting the quietest point between 80 - 120 regardless. With this in mind - the minelab preset is not far away either. If you would help, thanks, stevewilko [/QUOTE]
