Insert the washers as shown on the telescopic shaft. Install the telescopic shaft to its location on
the search coil. Secure by tightening the screw and nut.
Loosen the twist lock before mounting the telescopic shaft to the upper rod. Press down the pin
and engage the pieces together and tighten the twist lock after the pin is clicked into the hole.
Wind the cable of the search coil on the telescopic shaft without stretching too much. Plug the
connector on the cable to the search coil input socket on the system box and secure by
tightening the nut.
Loosen the twist lock of the telescopic shaft to extend or shorten it. Adjust the length of the shaft
by keeping the pin located on the rear pressed down and clicking the pin in any of the holes.
Secure by tightening the twist lock.
Insert the armrest band through its slot as shown in the figure. Loosen the screws and adjust the
armrest position to your comfort by sliding it down or up and secure by tightening the screws.

Battery Details
The device is supplied with 4 pieces of AA Alkaline batteries.
To remove the battery compartment cover, press on the latch and pull out. Insert the batteries
observing correct polarity of + (plus) and - (minus).
The device can be used for approximately 25-30 hours when the batteries are fully charged.
Operating time of other brands and types of batteries available on the market may vary.
AA Alkaline batteries are recommended for the best performance. Good quality Ni-MH
rechargeable batteries can be used, too. Rechargeable batteries with high mAh (capacity)
ratings offer extended operating times than batteries with lower rating. We recommend use of
minimum 2500mAh batteries.
Low Battery Level
Battery icon on the display shows the battery life status. When the charge decreases, the bars
inside the battery icon decrease, too. "Lo" message appears on the display when the batteries
are depleted and the device shuts down after a short period.

Assemble the device as per the instructions on page 1.
Insert the batteries by paying attention to +/- polarity.
Rotate the on/off switch located behind the device clockwise to turn on the
device. This switch also adjusts the volume.
When the device is turned on, it will start in the All Metal mode. You can
change the mode based on the area that you are searching.
To ground balance, push and hold the trigger forward and pump the search
coil up and down 3cm (1.2'') above the ground until a “beep” sound is heard.
You can increase the sensitivity if needed. Increasing the sensitivity will
offer you greater depth. However, if the surroundings or the ground cause
excessive noise in the device, you need to lower the sensitivity setting.
If the device receives a lot of ground noise in the All Metal mode causing a
disruption in the threshold's stability, you can increase the iSAT value.
If the ground is highly mineralized causing the coil to overload, decrease
the sensitivity until the ''Saturation'' message disappears from the screen.
Testing with various metals in discrimination modes is useful for getting
familiar with the sounds produced by the device.
Based on the IDs of the metals you don't want to detect, you can set the ID
Filter and ignore those metals. For instance, if you don’t want to detect
ferrous metals with 20 ID, you can adjust the ID Filter to 21.
You can now start searching.
Since your device operates with the motion principle, swing the search coil
right and left maintaining 5cm (2") distance above the ground. If the search
coil does not move, the device will not provide any warning tones even if
the coil is over a metal target.
When a target is detected, the ID of the target is displayed on the screen
and the cursor indicates its position in the ID and color scale. The device
also produces a warning tone based on the search mode selected.
Upon target detection, you can pinpoint the exact location of the target by
pulling and holding the trigger back.

Quick Guide

3 search modes adapted to different ground conditions and target types are offered by the
GOLD RACER. Names of the search modes are defined as All Metal, DISC.1, and DISC.2 on the
screen. You can easily switch between the modes by using the direction keys during your search.
The name of the selected mode is shown framed on screen. While in settings, the selection
cursor appears on the selected setting and the current mode name is underlined. The settings
for All Metal mode appears on the left side of the screen and the settings for both discrimination
modes appear on the right. Some settings are common to all modes. For more details, please
read the explanations for settings of each mode carefully.
All Metal Mode
It is the deepest mode of the device. Different than the discrimination modes, this mode features
a threshold tone which is continuously heard in the background.
The device does not discriminate targets while in the All Metal mode and detects all targets
(metal, mineralized rocks etc.). ID of the detected target is shown on the display (except for
negative hot rocks) and the same warning tone is provided for all targets. The warning tone
increases in pitch as the target is approached.
Sensitivity, threshold and iSAT settings in this mode are set to default values which provide the
best performance on different terrains. You can modify these settings based on ground
conditions.
Settings for All Metal Mode
Sensitivity
It is the depth setting of the All Metal mode. It is also used to eliminate the ambient
electromagnetic signals from the surrounding environment and noise signals transmitted from
ground.
The device starts in the All Metal mode. You
can change the mode using the +/- buttons.
Select a setting from the menu by using the
up/down buttons. The value of the selected
setting is shown on the display. You can
change the value by using the + and -
buttons.
If up/down and +/- buttons are kept
pressed for a certain period, options and
values change more rapidly.
If no button is pressed for a while after selecting a setting or changing its value, the selection
cursor automatically returns back to the selected mode. Pulling the trigger eliminates the
waiting time.
