LOCATOR
OPERATION
“PIN-POINTING” THE TARGET
Upon locating the target using the “Search or Survey” method, you
can detect the exact location of a target such as a “PK”, “MAG-
Nail”, or other steel or iron target by following these steps:
1. Change the GAIN setting to the lowest setting that will still define
the target, by using the “GAIN UP” or “Gain Down” button.
2. Bring the locator to a vertical position by simply allowing it to
swing vertical, while you hold the unit loosely.
3. Move the locator back & forth in such a fashion as to create an
imaginary “X” pattern over the target.
4. Move the center of the imaginary “X” directly over the target by
positioning the crossing position of the “X” at the “Peak” of the
signal response.
SEARCH OR SURVEY WITH THE ML3
Walk slowly, sweeping the locator back & forth in front of you. If
your target is small or very deep, use a higher GAIN setting and
walk slower, with a slower sweeping motion. Normally a
medium setting on the GAIN and a little less than normal
walking pace will do fine.
NOTE: Any ‘ferrous’ metal objects on your person, such as
watches, pocket knives, large belt buckles, cell phones and
steel-toed shoes will interfere if the locator is brought to close to
them, or is operated on the higher setting.

REPLACING THE BATTERIES
3(three) 9V Alkaline Batteries
1. Unscrew the cap on top of the ML-3 to expose holder end.
2. Pull the battery holder out by the tab so you can service it.
3. Replace all three 9V batteries with new ones.
4. Replace wires into housing.
5. Slide the battery holder back into the tube, tab end out.
6. Replace the cap to the ML-3 & properly discard old batteries.
7. Verify unit turns on.
Turn the POWER on or off by press-
ing the “ON/OFF” button on the keypad.
There is no volume control. To change the
“GAIN” (sensitivity) settings, repeatedly press the
“GAIN UP” button to increase the sensitivity, and the
“GAIN DOWN” button to decrease the sensitivity.
Each push of the “GAIN” button changes the sensitivity up or down
ONE increment at a time, out of 8 possible settings. A micro-
processor remembers the “GAIN settings, and when turned back
on, the locator returns to the last used setting before it was turned
off. Don’t know what GAIN setting you’re on? Press the “GAIN
DOWN” button several times (more than 7), to ensure that you are
on the lowest setting. Then press the “GAIN UP” button and count
up to 7 (or vice versa down from the highest setting.) If starting
from the lowest setting, 3 or 4 clicks up is a good setting to begin
locating. (All of our “ML” series locators have sensitivity settings
that are more ‘linear’. Beware of competitor models which take
larger non-linear ‘jumps’ between settings, which give the impres-
sion that their unit is more sensitive on lower settings.)
