QUICK-START DEM ONSTRATION
I. Supplies Needed
• a Nail • a Gold Ring (try several different size gold rings) • a Large Silver Coin
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. Power Up
Press
.
IV. Wave each object over the searchcoil
a. Notice the tones and Target-IDs for each object (assumes default DISC
setting):
OBJECT
TARGET-ID
TONE
Nail
lower (e.g. 10-35)
LOW
Gold Ring
medium (e.g.- Mid 50’s)
V.C.O.
Larger Gold Ring
medium (but higher than ID for smaller gold ring) V.C.O.
Silver Coin
higher (e.g.- 80-99)
High
b. Motion is required.
• Objects must be in motion over the searchcoil to be detected.
• Sweep objects flat over the searchcoil, parallel to the plane of the searchcoil.
V. Press
twice to activate the DISC selection
a. While sweeping the Nail back-and-forth, press
to
increase the DISC setting.
b. Continue to press
and increase the DISC setting.
• Notice that the Nail will be eliminated from detection at a certain DISC setting.
The nail is eliminated when the DISC setting is 40 numbers greater
than the target's ID.
Caution: Passing the nail at differing angles will yield different ID numbers.
• When the Nail is eliminated from detection, the IRON segment will still
flash but no tone will sound and no Target-ID will be indicated.
VI. Repeat Step V while waiving the Gold Ring, and then also
while waiving the Silver Coin
• Notice that the Gold Ring will be eliminated from detection.
• If the ID of the Silver Coin is greater than 80, then it will not be eliminated
from detection. But if the coin’s ID is less than 80, the tone will change
from V.C.O. to High Tone as DISC is adjusted.
VII. Press and hold PINPOINT
a. Hold a metal object motionless over the searchcoil.
b. Notice that motion is not required for detection.
c. Move the object closer, then farther away from the searchcoil.
• Notice the changing sound.
• Notice the changing depth values.
DEPTH INDICATOR
In Discrimination Mode, each time an object is detected, a Bar Graph
illuminates in addition to the Target-ID.
The Bar Graph is a graphic representation of the distance from the searchcoil,
and is calibrated to a coin-sized object.
• More bars indicate a deeper object.
• Fewer bars indicate a shallower object.
The scale for coin-sized objects, with sensitivity at maximum, is:
Display:
Depth:
>20cm
15cm-20cm
10cm-15cm
6cm-10cm
<6cm
(8”)*
(6”-8”)
(4”-6”)
(2.5”-4”)
(2.5”)**
* 5 Bars: If the object is a coin, it is deeply buried.
…or this could be the faint signal from a large, but very deeply buried,
object.
** 1 Bar: If the object is a coin, it is shallow.
…or this could be a large object more deeply buried.
