CONTROLS & FUNCTIONS
> PRIMARY AND SECONDARY OPERATING MODES
A “primary” operating mode is active when the MODE TRIGGER switch is in the Normal (center) position, and the “secondary” operating mode is active when the MODE TRIGGER is in the Swap position (pushed and held). The following front panel settings will show you how to achieve your favorite primary and secondary operating modes. This will allow you to quickly change modes without losing any settings to gain more information about your targets.

ALL METAL MODE
Your 1270 gives you two ways to search in all-metal operation: (1) by set- ting your NORMAL DISC to 0, or (2) by turning on the ALL METAL GROUND ADJUST (rotate knob clockwise). When using the ALL-METAL GROUND ADJUST mode, only the VOLUME and the SENSITIVITY con- trols are still active: you have temporarily disabled the other controls on the 1270 (it becomes the “primary” operating mode, as explained above). In this mode, you must manually adjust the 1270 for the type of ground you are searching. Turn the GROUND ADJUST knob switch on (to about “1”), and the sensitivity to about “8”. Make sure the search coil is not near any
