AUDIO TARGET IDENTIFICATION SYSTEM

Different types of metals will induce different types of sounds, depending on
your TONES setting.

There are 4 choices in DISCRIMINATION MODE:

The default setting is d3.
To choose from the above selections, press the TONES touch pad.
Each press of the TONES touch pad cycles to the next selection.

There are 4 choices in ALL-METALS MODE
A1, A2, A3, A4 - pitch varies with each setting.

d1. Medium-to-high pitch tone,

varying in proportion to target
signal strength. Large shallow
objects will produce a squeal. The
variable audio pitch provides you
more information about the
detected object. Volume and Pitch
increase with increase in signal
strength.

d3. Three different audio tones.

Bass Tone: Iron
Low Tone: Foil, 5¢, Tab and Zinc
High Tone: Dime, Qtr

d2. Iron produces a bass tone

regardless signal strength.
Volume varies in proportion to
signal strength. Non-ferrous
targets respond as in d1.

d4. Four Different audio tones

Bass Tone: Iron
Low Tone: Foil, Tab, and Zinc
Medium Tone: 5¢
High Tone: Dime, Qtr

QUICK-START DEM ONSTRATION

I. Supplies Needed

• a Nail • a Zinc Penny (dated after 1982)
• a Nickel • a Quarter

II. Position the Detector

a. Place the detector on a

table, with the searchcoil
hanging over the edge.
Or better, have a friend
hold the detector, with the
searchcoil off the ground.

b. Keep the searchcoil away

from walls, floors, and
metal objects.

c. Remove watches, rings, and jewelry.
d. Turn off lights or appliances, whose electromagnetic emissions may

cause interference.

e. Pivot the searchcoil back.

III. Click on detector with the left knob. Set it at the

12:00 position for this demonstration.

IV. Click the right knob to the lowest Disc

setting

V. Wave each object over the searchcoil.

a. Notice a different tone for each object:

Bas Tone:

Nail

Low Tone:

Nickle and Zinc Penny

High Tone:

Quarter

b. Motion is required.

Objects must be in motion over the searchcoil to be detected in this mode.

VI. Rotate the DISC (right) knob until the word “IRON” disappears from the

screen. Make sure that the word “FOIL” is still illuminated.

VII. Wave the nail over the searchcoil.

a. The nail will not be detected
b. The nail has been “discriminated out.”
