SILVER RANGE (1¢/25¢ icon):
indicates that the object is probably a silver coin. Some large aluminium objects might register within the 25¢/1¢
category.
b) tones
If the detector is set to the ALL METAL mode, it sounds a single tone when it detects any type of metal.
If you set the detector to the DISC or NOTCH modes, the built-in audio identification system sounds a unique
audio tone for each of the three categories of metal. This makes it easier to identify the metal being detected.
- The detector sounds a low tone when it detects small gold objects, a nail, a bottle cap or nickel.
- The medium tone is for aluminium pull tabs, zinc or copper items. Depending on the alloys used to make them,
about 15 percent of gold rings cause the detector to sound a medium tone.
- A high tone is for brass or silver items. Highly oxidized iron may generate a medium or high tone.
4. Operation
1- volume knob
2- function panel
3- operation mode buttons
4- regulation mode buttons
5- regulation buttons: ‘Up’ and ‘Dn’ (down)
6- power switch
7- headphones jack
a) Turning on the detector
First turn the volume knob (1) to 12 o’clock (halfway between min and max).
Slide the power switch (6) to ON. All symbols are displayed on the LCD screen. The detector sounds a high,
medium and low tone respectively.
After about 2 seconds, the detector automatically goes ALL METAL mode, with the regulation buttons (5)
available for the sensitivity (SENS) adjustment. The standard value of SENS is 5.
b) Setting the operating mode
The detector has three operating modes: ALL METAL, DISC and NOTCH. You can select the desired mode by
pressing the corresponding key (3) at the left of the function panel. Whatever the mode, upon detecting
something, the detector will always sound a tone and indicate the probable type of metal by means of an arrow
underneath the icons, and also indicate the depth of the object.
- ALL METAL: used for detecting any type of metal. In this mode, only the SENS value can be adjusted.
- DISC: used for target discrimination. You can set the target range by pressing the DISC/NOTCH regulation
mode button (4) and then the UP or DOWN button (5). The detector can detect the metal type indicated on the
display. All other metal types are rejected. For example, if you set the DISC level 4 segments from MAX to
MIN, the detector can detect S-CAPS, 1¢ or 25¢ whilst other types of metal are rejected. The detection range
can only be extended from silver towards gold.
- NOTCH: used to detect purer types of silver or gold. When you press the NOTCH operation mode button (3),
the detector will only detect purer silver and gold objects, discarding most alloys. Pressing the DISC/NOTCH
button and then the Up button will result in less pure objects being detected. This mode works from the ‘pure’
metals on both sides towards the middle.
