TO THE OWNER

Congratulations! As the proud owner of the Garrett

GTP 1350 you have joined an international family of treasure hunters. Men, women and children alike have used their Garrett detectors to find coins, relics and gold nuggets that are valued in the millions of dollars. To get the most out your GTP 1350 and

treasure hunting experiences be sure to carefully

read through this Owner’s Manual!

Your GTP 1350 is the first of its class to offer size

information that will enable you to know more about your target before you dig. With its exciting profiling

technology, you can know the size (Small, Medium,

Large) of a target before you dig. And when coupled

with Garrett’s highly acclaimed PROformance searchcoils, you search deeper and cover more ground per sweep than with traditional searchcoils.

Your GTP 1350 is also engineered with DSP enhanced

technology and is backed by 40 years of metal detection research and development by Garrett’s

Graphic Target Proling 1350

™

leading team of engineers. It is unparalleled in its

ability to locate coins, jewelry and other metallic objects at greater depths than any other metal

detector in its class. With Garrett’s revolutionary

Graphic Target Analyzer (GTA) display that offers

target acceptance/rejection, precise discrimination and other key information, you can spend more time digging treasure and less time digging trash.

As the one of the world’s most intelligent detectors,

the GTP 1350 is factory preset to begin operation in the COINS mode. Simply press the POWER touchpad on your new GTP 1350 and immediately

begin hunting without the troublesome interference

from typical trash items or ground minerals. Of course, you can easily adjust the detector to operate in other hunting modes.

Again, welcome to the Garrett treasure hunting family. In becoming a part of this great tradition and hobby, you have made the right start to successful

treasure hunting.

GTP ASSEMBLY

No tools are required to assemble the GTP 1350. Hand tighten all necessary parts.

1. Press the two Mounting Washers into the Lower

Stem. See Figure 1.

Figure 1

2. Slide the searchcoil onto the Stem (Figure 2).

Figure 2

Garrett Metal Detectors

3. Insert the Threaded Bolt through the holes of

the Lower Stem and Searchcoil. Hand-tighten the

searchcoil assembly with the remaining Wing Nut.

See Figure 3.

Figure 3

4. Depress the Spring Clip and insert the Control Housing into the Upper Stem.

5. Depress the Spring Clip in the Lower Stem to adjust to the most comfortable operating length.

See Figure 4.

Figure 4

6. Wrap the Searchcoil cable snugly about the stem with the first turn of the cable over the stem. See

Figure 5.

Figure 5

7. Insert the Cable into the Connector of the Control

Housing and hand-tighten. See Figure 6.

TOUCHPAD FUNCTIONS

The GTP 1350 has eight (8) touchpads that control

all operating functions. The battery pack and headphone jack are located beneath the arm rest.

POWER Touchpad

Press the POWER touchpad once to turn the

detector ON or OFF. The detector will beep twice when turned ON and once when turned OFF.

If, after making adjustments to the 1350, you wish to return to the factory recommended settings, press and hold the POWER touchpad for approximately

ten (10) seconds, or until the detector beeps twice.

Graphic Target Proling 1350

™

Each time the GTP 1350 is turned on, it returns to the most recent settings it was programmed to use. However, modifications made to the COINS,

JEWELRY, RELIC and ZERO Discrimination settings are not stored by the 1350 when turned OFF.

MENU / SCROLL Touchpad

Press the MENU / SCROLL touchpad to scroll through the MENU options to make adjustments to the detector’s settings.

Press the MENU touchpad to advance to each

item in the MENU selection or press the OPERATE

touchpad after making an adjustment to resume hunting. The 1350 will automatically return to the

OPERATE mode if no touchpads are pressed within 30 seconds.

MODE (Discrimination Mode) Press the (+) or (-) touchpad to select the desired

Discrimination MODE: COINS, JEWELRY, RELICS, ZERO, or CUSTOM. The selected

MODE does not flash.

Garrett Metal Detectors

COINS MODE—Designed to eliminate detection of lower conductivity trash targets such as

iron, bottle caps, most pull tabs and other objects normally encountered in coin hunting. Some bent pull tabs and pieces of tabs may not be eliminated

from detection. Some digging of junk targets is to

be expected on occasion.

JEWELRY MODE—Designed to eliminate trash targets such as lower conductivity items and

bottle caps, while still detecting jewelry.

RELICS MODE—Designed to eliminate trash targets normally associated with relic hunting, while retaining good targets in the lower conductivity range.

ZERO MODE—Designed to hunt with no discrimination and alert the operator of every metal target.

CUSTOM MODE—A Discrimination Mode that is

programmed solely by the operator. The

GTP

Graphic Target Proling 1350

™

1350 is factory preset with the CUSTOM Mode set the same as the COINS Mode. By using the ACCEPT / REJECT touchpad, an operator can modify the Discrimination settings to individual

specifications, which will be retained in the

CUSTOM Mode.

SENSITIVITY Press the (+) or (-) touchpad to select the desired SENSITIVITY level, indicated on the Lower Scale of the LCD panel. The 1350’s Sensitivity setting

can be adjusted from 3 (least sensitive) to 12

(most sensitive).

The default SENSITIVITY setting is set to 9 (approximately 75 percent). It may be necessary

to reduce the SENSITIVITY setting in locations

where abnormal amounts of interference, trash

or other metal detectors are present. In these situations, reduce the sensitivity until the audio

becomes stable. When searching for very small or very deep targets it might be beneficial to

increase the sensitivity setting as much as

Garrett Metal Detectors

possible, prior to the point where the detector becomes unstable.

AUDIO THRESHOLD LEVEL Press the (+) or (-) touchpad to adjust the audio THRESHOLD level, indicated on the Lower Scale of the LCD panel. The audio THRESHOLD refers

to the volume of the background “hum” made by the detector when no metal is being detected.

FREQUENCY

Press the (+) or (-) touchpad to select between 4 (four) operating FREQUENCY settings, indicated

on the Lower Scale of the LCD panel. The

FREQUENCY setting may need to be changed when nearby electronic equipment or other metal

detectors cause interference.

VOLUME Press the (+) or (-) touchpad to adjust the VOLUME, indicated on the Lower Scale of the LCD panel. The VOLUME setting adjusts the sound level made when a target is detected.

Graphic Target Proling 1350

™

TONE Press the (+) or (-) touchpad to adjust the TONE, indicated on the Lower Scale of the LCD panel. The TONE refers to the pitch of the sound the detector makes when a target is found.

SALT ELIMINATION

Press the (+) touchpad to activate SALT ELIMINATION or the (-) touchpad to deactivate (flashing) SALT ELIMINATION. The SALT ELIMINATION MODE eliminates interference caused by wetted salt; a feature that is particularly helpful when hunting on saltwater beaches.

TONE ID Press the (+) touchpad to activate the TONE ID or the (-) touchpad to deactivate (flashing) the TONE ID. When activated, the TONE ID feature produces tones of varying pitches to indicate a target’s conductivity: high conductivity targets produce a high-pitched belltone; medium conductivity targets produce a standard-pitched

tone; and low conductivity targets produce a low-

Garrett Metal Detectors

pitched audio signal. A high-pitched tone replaces the standard belltone when the PROFILING feature is activated. (See Table on Page 18 for

additional information).

BACKLIGHT Press the (+) touchpad to activate the BACKLIGHT or the (-) touchpad to deactivate (flashing) the

BACKLIGHT. The BACKLIGHT illuminates

the LCD screen for low light or night hunting conditions.

BATTERY TYPE

When using rechargeable batteries press the (+) touchpad to activate the RECHARGEABLE battery option. Press the (-) touchpad to deactivate (flashing) the RECHARGEABLE battery option when using standard batteries. This setting affects only the battery

meter readings, not detector operation.
