POWERING UP
Press the ON touch pad. The detector will emit a low tone followed by a High tone.
All display segments will illuminate momentarily
Sensitivity
Upon power-up, the detector defaults to 3/4 sensitivity. To increase to full sensitivity, press the Sensitivity ▲ touch pad. Keep in mind that at higher sensitivity levels, the detector is susceptible to electromagnetic interference from electronic devices. Common sources of EMI are electric power lines, motors, and household appliances. Reduce sensitivity if the detector emits false signals or acts erratically.
UNDERSTANDING THE DISPLAY
The LEFT SIDE of the display has a dual purpose:
SENSITIVITY LEVEL:
Upon power-up, and after pressing either the up- or down-sensitivity pads, the pyramid-shaped display indicates the detector's sensitivity level. The sensitivity level can be changed using the up- and down-pads. At maximum sensitivity, the unit can detect a coin-sized metal object buried about 6" beneath the surface; larger objects can be detected much deeper.
DEPTH INDICATION:
After detecting an object, the pyramid-shaped display indicates the approximate depth of buried, coin-sized objects. Objects at or near the surface will illuminate the single segment at the top of the scale. More deeply buried objects will illuminate more segments, indicating depths of 2, 4, or 6 inches, as identified to the left of the display.
Depth Indication is calibrated for coin-sized objects and depth is indicated in inches. Large and irregularly-shaped objects will yield less reliable depth readings.
The RIGHT SIDE of the display classifies objects into three categories.
Silver/Copper:
Objects composed of silver and cooper will illuminate this arrow. Buried and heavily oxidized metal objects, such as old tin cans, can also fall into this category.
Mid-Range:
Mid-range objects cover a large variety of metals. Among them are: pull-tabs from beverage containers, nickels, medium-sized gold objects, some types of aluminum, and zinc.
Iron:
All ferrous objects, and some smaller aluminum objects, fall into the iron category. Small gold objects can also fall into this range.
Low Battery BOTTOM RIGHT SIDE of the LCD.
This indicator illuminates, and remains illuminated, when the 9-volt batteries have discharged to a level of 7.35 volts.
Reading the display in the field:
The display will indicate both the DEPTH and TARGET IDENTIFICATION category of each object detected. After a target is detected, these indicators will remain illuminated with this information until the next target has been detected.
The MODE CONTROL
The MODE touchpad allows for the elimination from detection of unwanted metal objects. By pressing MODE, the user toggles among four different discrimination settings.
During MODE (or discrimination) selection, the SENSITIVITY INDICATOR on the left of the display will flash continually. The detector will remain in this discrimination selection mode for 10 seconds until a metal object has been detected.
If an object is detected during mode selection, the detector will exit mode selection. If this happens, you will need to press MODE again and begin mode selection over again. To avoid this,
keep the detector stationary and reduce sensitivity before pressing MODE.
The MODE touch-pad has two functions:
Each first press of MODE will be followed by.
A distinctive tone or tones, indicating the detector's stored discriminating setting.
HIGH TONE - no object eliminated.
LOW TONE - iron eliminated.
MEDIUM TONE - mid-range metals eliminated.
LOW & MEDIUM TONE - irons and mid-range metals both eliminated.
Flashing target and sensitivity indicators. The flashing target indicators point to the targets eliminated. Each subsequent press of MODE will toggle between discrimination settings.
The flashing arrow indicates the target category eliminated. The detector will store the current discrimination setting until the power is turned off.
