OPERATION OF THE TRASH ELIMINATOR CONTROL –

The Trash Eliminator Control

is used to reject or discriminate

unwanted trash targets. When the control is set to '0' your Cobra
Beach Magnet will be in the All-Metal Mode and will respond to all
targets. When you increase the control to a higher number the de-
tector will begin to reject small iron targets first then most small foil
pieces and then pull tabs. Study the below chart to get a better un-
derstanding of the different levels that trash target are eliminated.

Note:

Most

Eliminated Trash Targets

will give a broken or chattered sound when

discriminated, this is normal and is a design feature of this underwater detector. It
was designed this way so you can easily identify trash targets. Some trash targets
will give No sounds at all. Practice using the

Elimination Control

by putting some

different coins and trash items on the ground in a straight line about 10 inches
apart. Pass each item once and then come back and increase the elimination
control knob by one number and listen to the changes in the audio response on
the trash targets as you keep increasing the control by one. Remember even good
targets can be eliminated at the maximum discrimination settings.

STARTING POINT

(Pre-Set

Position)

By starting out at the Pre-set point the

COBRA Beach Magnet

is set at the

normal detection depth range

. The normal range is

good for most soil conditions, but by increasing this control clock-
wise to the maximum position you will get better depth on older
coins. This control is extremely helpful in elimination false signals
caused by high minerals. If you are experiencing false signals you
should decrease this control until these signals are minimized.

TIP:

Try running the

COBRA Beach Magnet

in the highest

Detection Depth Range that you can (with minimal false signals)
so the detector will give you maximum coin depth.
