GETTING STARTED This sections shows you how to quickly set up your detector to begin detecting with minimal adjustment, and describes how to identify and adjust key detector functions. Quick Start Beginning with Factory Default Settings is recommended for Quick-Start. 1. Turn On 2. Wait for Noise Cancel 3. Pump coil (< 10 s) 4. Begin Detecting GPX 6000 automatically compensates for ground noise, EMI, and sensitivity within 20 seconds of turning on.

Bluetooth Headphones Any standard Bluetooth headphones can be used with the GPX 6000, however use of the Minelab ML 100 wireless headphones is recommended for optimum wireless audio performance. Minelab ML 100 headphones use aptX™ Low Latency technology, and will deliver faster audio than standard Bluetooth® headphones. aptX™ Low Latency technology is faster than standard Bluetooth, with a delay of 40 ms, giving a faster detection response. 1.

Coils Selecting the correct coil size and configuration allows you to optimise your GPX 6000’s performance in a range of detecting scenarios. Understanding when to use each coil will increase the productivity of your detecting sessions. GPX 11 Mono The GPX 11 Mono coil is a great general-purpose coil that is recommended for most detecting conditions. It is a good all‑rounder that has excellent depth and sensitivity.
BEYOND DEFAULT SETTINGS Go beyond the factory default settings to gain even greater control of your GPX 6000. This section describes how and why you should adjust key detector settings to optimise your GPX 6000 for specific detecting scenarios. Sensitivity Choose the highest stable sensitivity setting for optimum performance, or use the automatic settings.
Ground Balance Ground Balancing enables the detector to separate unwanted ground signals from target signals. The GPX 6000 features Automatic Ground Balance, as well as Quick‑Trak and Ground Type settings for even greater Ground Balance control. Quick-Trak GPX 6000 tracks automatically to changing ground conditions during normal use. It is effective for typical detecting in less variable ground.
Ground Balance Procedure In order to achieve good ground balance follow the recommended procedure. The procedure steps through a sequence that will help you to identify the type of ground you are detecting and its ground noise levels, and then provides the best steps to manage that noise. Ground is categorised into four types: Normal — Ground with very low levels of mineralisation. ` Difficult — Ground that has high levels of mineralisation.
Mono coil advanced procedure The GPX 6000 detector combined with a mono coil is a powerful combination that is ultra sensitive to gold nuggets. Mono coils go deeper than Double-D coils, however they are more susceptible to noise. Adjust the detector settings to the following settings: 1. Apply recommended settings ` Sensitivity: Level 6 (manual) ` Ground Type: Normal ` Coil Type: Mono These settings provide the best basis for the advanced Mono and Double-D coil detecting procedures. 2.
Double-D coil advanced procedure The GPX 6000 Double-D coil excels in locations that have very high levels of interference. They are less noisy than mono coils, but are also less sensitive. Generally, the Double-D coil should only be used once the Mono coil advanced procedure (page 14) has been completed without success. It can also be used in areas that have known high levels of EMI or very salty (conductive) soils. 1. Turn on ` Connect the Double-D coil.
Noise Cancel If audio responses become erratic, initiate the Noise Cancel process to automatically select a quieter detecting channel. Performing Noise Cancel 1. Press the Noise Cancel button. Press the Noise Cancel button for <2 seconds. The Noise Cancel icon will flash while Noise Cancel is in progress (approximately 5 seconds). 2. Wait for 5 seconds ` If the detector is quiet, begin detecting.
ADVANCED CONCEPTS Identifying the source of detector noise EMI: Hold the coil still more than 100 mm (4 inches) above the ground. If noise is present, it is likely to be EMI. Conductivity: Pump the coil up-and-down approximately 1 metre (3.3 feet) above the ground. If noise is present, it is likely to be casued by Conductivity. Ground Noise: Swing the coil over the ground. If noise is present, it is likely to be ground noise. Mono vs.
Double-D Modes manage noise from EMI or conductive ground when using the GPX 14 Double-D coil. These modes are only available when a Double-D coil is in use. Change the Double-D mode 1. Press the Noise Cancel button for > 2.5 seconds to toggle between EMI Cancel and Conductive Ground Cancel. > 2.5 s Note: Double-D modes are only available when the Double-D coil is in use. 2. The icon for the enabled Double-D mode is displayed.
TROUBLESHOOTING, CARE & SAFETY Errors Coil Error System Error If there is a coil error, the error icon and the coil icon is displayed for 5 seconds before the detector automatically powers off. If there is a system error, the error icon is displayed for 5 seconds before the detector automatically powers off. Error Troubleshooting Error icon and coil icon are displayed, the detector turns off after 5 seconds 1. 2. 3. 4. Check that the coil connector is connected properly at the front of the control box.
General Troubleshooting Detector does not turn on, or turns off by itself 1. Charge the battery. No sound — Wired headphones 1. 2. 3. 4. 5. Check that the detector is on, and start-up has completed. Check that the headphones are plugged in. Check that volume is set to an audible level. Unplug the headphones and confirm that the detector speaker is audible. If available, try using a different set of headphones. No sound — ML 100 Headphones 1. 2. 3. 4. 5. 6. 7. Check that the headphones are turned on.
Detector Care and Safety Wash your hands before handling the detector after applying sunscreen or insect repellents. Do not use solvents to clean. Use a damp cloth with a mild soap detergent. Never allow the detector to come into contact with gasoline/petrol or other petroleum-based liquids. Avoid getting sand and grit in the shafts and fastenings (e.g. coil yoke assembly and twist locks). If sand and grit accumulates in these parts they should be wiped clean with a damp cloth.
