metal. This may be tested quickly by pulling the trigger switch and sweep- ing over an area of about one square foot. If no signal is detected, release the trigger switch and raise the search coil off the ground, and lower it back down two or three times (also known as “bobbing”). If an audible sound is heard, turn the GROUND ADJUST knob slightly clockwise. Repeat this procedure until no sound is heard when raising and lowering the coil to the ground. Once you have the 1270 balanced to the type of ground you are searching, you may begin sweeping the coil at a comfortable pace. Approxi- mately four feet per second will give you optimal performance. Remember, the ALL METAL GROUND ADJUST mode is a MOTION mode. Slight movement of the coil is required to detect an object. While in this mode, if the IRON DISC toggle is OFF, pushing the MODE TRIGGER forward switches the 1270 into the NORMAL DISC mode. If the IRON DISC toggle is ON, pushing the MODE TRIGGER forward switches the 1270 into the IRON DISC mode. SEE PRIMARY & SECONDARY OPERATING MODES PG. 7)
