is a professional metal
detector. While the most
difficult aspects of metal detecting
have been automated, it is a
sophisticated electronic device which
requires an understanding of some basic
features and metal detecting concepts.
If you do not have prior experience with a
metal detector, we strongly recommend that you:
1) Adjust the Sensitivity to a low setting in the event
of false signals. Always begin use at a reduced
sensitivity level; increase to full sen

TERMINOLOGY The following terms are used throughout the manual, and are standard terminology among detectorists. ELIMINATION Reference to a metal being "eliminated" means that the detector will not emit a tone, nor light up an indicator, when a specified object passes through the coil’s detection field. DISCRIMINATION When the detector emits different tones for different types of metals, and when the detector "eliminates" certain metals, we refer to this as the detector "discriminating" among di

ASSEMBLY Assembly is easy and requires no tools. 1 Position the lower stem (the straight tube) ● with the silver button toward the back. Using the bolt and knurled knob, attach the search coil to the plastic extension protruding from the lower stem. 2 Press the button on ● the upper end of the lower stem, and slide the lower stem into the upper stem. Adjust the stem to a length that lets you maintain a comfortable upright posture, with your arm relaxed at your side, and the search coil paralle

ASSEMBLY Adjusting the Arm Rest Most people will find the standard position of the arm rest very comfortable. Very large forearms and short forearms (particularly children’s arms), can be accommodated by moving the arm rest forward. The arm rest is adjustable to three positions. To adjust, remove the screw from the underside, then press the silver button and move the arm rest to one of the alternate positions. If you cannot fully depress the button with your finger, use a narrow object, such as

To install the batteries: 1Remove the ● battery cover by disengaging the clip at the back. 2 Align the polarity ● of the batteries correctly, with the positive "+" toward the coil plug connection, as indicated by the + and – indicators on the housing. 3 Insert (2) 9-Volt ALKALINE batteries, with the contacts pointed inward, ● and press down on the back of the batteries to snap them into place. Some brands of batteries will require moderate force to clear

At this setting, the detector will detect a coin-sized object, such as a quarter, buried approximately seven inches deep. To change the sensitivity level, and thus the detection depth,

continued BASIC OPERATION DEFAULT OPERATION The detector defaults to ALL METAL mode after powering on. In this mode, all types of metals will be detected. An object’s probable identification is indicated by the arrows at the top of the display. In addition, the probable depth of coin-sized objects is indicated by the large numeric indicator in the center of the display. All detected objects will cause the depth indicator to illuminate. The depth indication is not accurate for larger object

continued BASIC OPERATION To increase the level of discrimination, press the DISCRIMINATION ▲ touch pad. Each time the ▲ pad is depressed, an additional "R" will appear, thus eliminating from detection the objects which fall into the corresponding categories. To decrease the level of discrimination, press the DISCRIMINATION ▼ touch pad. Each time the ▼ pad is depressed, an illuminated "R" will disappear, thus returning to detection the objects which fall into the corresponding categories. Dis

To demonstrate the ZAP control: 1) Set the detector in All-Metal Mode Note: ZAP functions in all modes, but is best demonstrated first from the All-Metal Mode. 2) Pass the search coil over an undesirable object. 3) Notice the Target Indication Note: You can only ZAP objects that register under the five left-most segments (from Iron to Zinc). 4) Press ZAP.

AUDIO TARGET IDENTIFICATION While the LCD (Liquid Crystal Display) is very accurate in identifying buried objects, the user in the field does not always maintain the display screen in his field of vision. Therefore, we have incorporated an audio feedback mechanism to alert the user to the nature of buried objects. This audio feedback system first alerts the user to the presence and classification of objects, whose nature and location can be confirmed using the LCD display. The detector can soun

SENSITIVITY ADJUSTMENT ELECTROMAGNETIC INTERFERENCE The principle use for the Sensitivity Control is to eliminate Electromagnetic Interference (EMI). A hobby metal detector is an extremely sensitive device; the search coil creates its own magnetic field and acts like an antenna. If your detector beeps erratically when the search coil is motionless, the unit is probably detecting another electromagnetic field. Common sources of EMI are electric power lines, both suspended and buried, motors, and
