OPERATING INSTRUCTIONS

GTAx 1250 DETECTOR

The control panels of these detectors have eight (8) touchpads which control all the operating
functions of the detector. Beneath the Arm Cuff are the Battery Pack and the headphone jack.

TOUCHPAD CONTROL FUNCTIONS:

Power: Turns the detector on, off, or resets the detector to the factory settings.

Press once to turn the detector on.
As the detector starts the battery condition is checked audibly and displayed on the LCD

Display. Also, during the detector's start-up the detector adjusts automatically for the
elimination of ground minerals, and the audio threshold is set to a point that is just silent. The
last used pattern of discrimination is re-established and displayed on the LCD face.

B. Depth-- (Also referred to as sensitivity). Permits the regulation of depth/sensitivity

using the + and - touchpads.

C. Audio Threshold Level-- Permits the regulation of the Audio Threshold using the +

and - touchpads.

D. Frequency: Permits regulation between the four (4) operating frequencies for the

elimination of interference from ambient electronic or atmospheric conditions as well
as the electronic field transmitted by a nearby metal detector.

E. Volume--Permits regulation of the volume level of the target sound using the + and -

touchpads.

F. Tone--Permits regulation of the Tone (bass to treble) that is offered through the

detectors speaker or headphones.

G. Salt Elimination: A Search Aid provided to eliminate the interference caused by the

presence of wetted salt.

H. Belltone:--The Tri-Level Audio System. Belltone is the factory setting that is

sounded when a target of high conductivity is encountered. Other targets will report
a standard audio signal and low conductivity targets will give a low audio sound. Use

the + or - arrows to turn Belltone audio on or off.
Backlight:-- Use this function to light the detector control panel so it may be seen at
night or in dark places.

I. Battery Type

Operate: Returns to the hunting mode after any change or adjustment of the controls.
Accept and Reject: Permits acceptance or rejection of specific targets to establish

discrimination notches, as shown on the Lower Scale.
Pinpoint: Activates the Pinpointing function and causes the depth of coin-sized items to be

shown on the Lower Scale.

Last Mode: Returns the detector to the operating mode previously used.
+ and - Arrows: Used to move the Target ID cursor when setting the discrimination notches

and use these arrows to alternate between selections when changing operating modes. These
arrows are also used when adjusting the Depth/Sensitivity, Audio Threshold, Frequency,
Volume, and Tone levels. As well, use these arrows when selecting the Salt Elimination,
Belltone tri-level audio, Backlight, and for Battery Type Selection.
The active feature or function will be displayed by steady illumination. Options available will be
flashing. The arrows allow movement between the options as desired. Where no options exist
the feature will be flashing (not in use) or steady (in use). + Arrow turns functions on, the ­Arrow turns them off.

Special Note:

If you are ever unsure about the settings of your detector, simply
touchpad for approximately 10 seconds. The detector will emit an audio signal and the factory
default settings will be restored.

Graphic Display Information:

Above the LCD Display is a guide of targets for use with the Target Cursor to assist in the
identification of detected items.
those that correspond with segments which are turned on will give an audio response.

The Upper Scale of the LCD indicates the target found, and the setting levels of the selected
operating modes. This scale indicates the maximum Pinpoint signal. It also shows the cursor
location for changing discrimination notches.

The Lower Scale of the LCD indicates the discrimination segments. Those that are illuminated
represent the discrimination pattern established. This scale, when pinpointing, indicates the
depth of coin-sized targets.

Battery:

Indicates the condition of the detector's batteries. Batteries should be replaced when there is
only one segment illuminated. With the + or - the battery scale can be regulated to the type of
batteries being used.

Note: All metal items will be indicated on the display but only

press and hold the Power

ASSEMBLY INSTRUCTIONS:

1. Insert the Button ends of the Spring clip into the white lower stem. This will allow the overall
stem length to be adjusted for operating comfort.

2. Attach the lower stem to the searchcoil by inserting the two washers into the stem and slip
the searchcoil onto the stem. Insert the threaded bolt through the holes and
two knobs.

3. Install the upper stem to the lower and then this assembly to the GTA housing by
depressing the two buttons and coupling the stem to the housing. Adjust for the most
comfortable operating length.

4. Wrap the searchcoil cable snugly about the stem with the first turn of the cable over the
stem.

5. Insert the cable connector into the connector on the housing and

hand-tighten securely.

OPERATING INSTRUCTIONS:

Lower the searchcoil to a level about one foot above the ground.
Press and release the POWER touchpad. The detector will give two (2) audio beeps, You will

then be ready to search. The Audio Threshold level is established , the Automatic Ground
Balance circuitry has set the parameters for the most effective search and the Discrimination
pattern is established for the last used mode.

SCANNING:

Scan the searchcoil in front of you in a straight line or a flat arc about your body. Keep the coil
level to the surface at a height of about one to two inches above the ground. This is
approximately grass-top height. The scanning speed should be about one to two feet per
second.

The presence of metal will be indicated by an audio sound and a LCD cursor on the Graphic
Display. Make two or three repeated scans over the target to determine precisely the targets
location. Listen for the loudest, most pronounced audio signal. The Target ID Cursor will
indicate the target's probable identity on the Display. The Target Guide above the cursor is an
aid in determining the identity of the target.

PINPOINTING:

Precise pinpointing is an important feature of your detector.
Touchpad and the searchcoil can remain steady and hover over the target. Slight movements
of the searchcoil will be reflected on the Upper Scale of the GTA Display. The greatest
deflection or illumination of segments-left to right- on the Upper Scale indicates the target is
directly beneath the center of the searchcoil. At the same time on the Lower Scale the
illuminated segments, left to right, indicate the depth of coin-sized items.

Another method of Pinpointing and Depth Reading used by many treasure hunters is as
follows. After acquiring a target, set the coil on the ground near but not directly over the target,
then press and hold the Pinpoint Touchpad. Do not lift the coil from the surface but slide it
around watching the LCD Display. When the two rows of segments touch each other, the
target is beneath the center of the coil at the depth indicated by the lower scale.

Press and hold the PINPOINT
