SubSurface Instrument ML-1 Instruction Manual

SEARCH OR SURVEY WITH THE ML-1

When searching for a target, 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 sweeping the locator
from side to side on a slow 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.
"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 by the handle.
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.

REPLACING THE BATTERIES

The ML-1does not have a
Low Battery indicator, erratic
behavior, such as no Gain
change and unable to turn the
unit off, can be an indication of
this condition.
The ML-1M produces a
"flashing" battery icon in the lower right corner of the LCD, this
is an indication that only 5% of battery life is remaining and you
should replace batteries soon.
1. Remove and disposed the old batteries. Look for the "+"
and "-" markings in the battery box and insert the new
batteries accordingly.
2. Once both batteries are installed and you double-checked
the polarity of both batteries, check for correct operation of
the instrument.
3. Once operation is verified, replace the battery box cover.
You can use a coin to turn the capture screw in the battery
box cover, do not over-tighten.
