Sensitivity & Target Elimination

Adjusting Sensitivity

The 

left knob 

clicks on to power the detector on.

After turning on, the left knob is used to control the detector’s sensitivity level.
In the 100% clockwise position, the detector is at maximum sensitivity. At this
level, the detector will detect a coin-sized object, like a quarter, up to 5” away
from the coil.  Very large metal objects will be detected up to one and one-half
feet from the search coil at maximum sensitivity.

Reduce the sensitivity if the detector chatters or emits false signals; your
detector is probably reacting to electromagnetic interference.

Target Elimination

The 

right knob 

is used to eliminate unwanted metals from detection.

For instance, you may be searching for coins, and want to eliminate objects like
nails, bolts, or pull-tabs from detection.

As you turn the right knob clockwise, you progressively eliminate different
types of metals from detection.  As you rotate the right knob, you first eliminate
iron objects from detection. Iron objects include nails, bolts, old cans, and tools.
Next, you eliminate nickels, pull-tabs, and finally zinc pennies.

Gold is also eliminated from detection with the right knob.  First smaller gold
objects are eliminated; as you rotate the knob further, larger gold objects are
eliminated. Silver objects, like high-value coins, are not eliminated from
detection.

Refer to this scale for the relative positions at which different types of metals
are eliminated from detection:

Finding Your Lost Metal Objects

Start with the 

eliminator

knob set

to a minimum (counterclockwise)
setting so as not to eliminate any
metal objects from detection.

Quick-Start Demo

Try this quick way to demonstrate the basic features of your HandyMan

:

I.

Supplies Needed
a. A nail
b. A zinc penny (pennies dated after 1982 are made of zinc)
c. A quarter

II. 

Position Your Detector

One person holds the detector still, so that another can sweep
coins under the coil.
Sweep coins under the bottom of the search coil.

III.

Beginning Settings

a. Left Knob:

At 6:00 position

b. Right Knob: Click on, but keep counterclockwise

IV. 

Detecting All Types of Metals

a. Wave each object over the search coil.  Notice the tone is

loudest as the object passes over the center.

b. Pass each object at varying distances from the search coil.

Notice that the sound gets louder as the object moves closer to
the search coil. Also notice that beyond a certain distance, the
object is no longer detected.

V. 

Eliminating Some Metals

a. Wave the nail and slowly turn the right knob to the right.

• Notice where the nail is eliminated from detection

b. Wave the penny and keep turning the right knob until the

penny is eliminated from detection

c. Wave the quarter

• Notice that the quarter is never eliminated from detection.
