Setup and Assembly

1. Attach the Search Coil: Connect the search coil to the lower stem using the provided bolt and nut. Ensure it is securely fastened but allows for slight angle adjustment.
2. Assemble the Stem: Connect the lower stem to the upper stem. Insert the control unit onto the upper stem and secure it.
3. Install Batteries: Open the battery compartment on the control unit. Insert two 9V 6F22 alkaline batteries, observing the correct polarity. Close the compartment securely.
4. Adjust Length: Adjust the length of the stem to a comfortable height, typically where the search coil is parallel to the ground when you stand upright. The adjustable rod ranges from 26" to 38.6" (total length 40" to 51").
5. Connect Coil Cable: Wrap the search coil cable around the stem and plug the connector into the corresponding port on the control unit. Ensure the connection is firm.

Operating Instructions

LCD Display Overview

The backlit LCD screen displays critical information:

• Target ID: Indicates the probable type of metal detected (Ferrous, Non-Ferrous, Gold, etc.).
• Depth Indication: Shows estimated depth of the target (2", 4", 6", 8" and+).
• Operating Mode: Displays the currently selected detection mode.
• Sensitivity Level: Indicates the current sensitivity setting (5 grades).
• Battery Level: Shows remaining battery power (4 grades).
• Signal Strength: Visual indication of target signal strength (5 grades).

Operation Modes

Press the MODE button to cycle through the 5 distinct operation modes:

• All-Metal Mode: Detects all types of metal without discrimination. Ideal for general searching or when the target metal type is unknown.
• Discrimination (DISC) Mode: Allows you to eliminate unwanted metals from detection. The detector will ignore metals below a certain conductivity threshold.
• Memory Mode: Stores a specific target ID and only detects that type of metal.
• Jewelry Mode: Optimized for finding small precious metals like rings, earrings, and other jewelry.
• Pinpoint (PP) Mode (Non-motion): Used to precisely locate the exact position of a detected target. This mode does not require the search coil to be in motion. Press the PP button to activate.

Sensitivity Adjustment

Use the SENS (Sensitivity) buttons (up/down arrows) to adjust the detection sensitivity. There are 5 grades of sensitivity. Higher sensitivity increases detection depth but may also increase false signals in mineralized ground.

Volume Control

Adjust the audio volume using the VOL (Volume) buttons. There are 3 grades of volume. The unique audio prompt emits 3 different tones for different types of metals.

Using the Waterproof Search Coil

The 10-inch search coil is IP68 waterproof, allowing for detection in shallow water, such as beaches, streams, or ponds. Important: The control box is NOT waterproof and must be kept dry at all times.

Maintenance

• Cleaning: Wipe the detector with a damp cloth after each use. Do not use abrasive cleaners or solvents. The search coil can be rinsed with fresh water.
• Storage: Store the detector in a dry, cool place when not in use. Remove batteries if storing for extended periods to prevent leakage.
• Battery Care: Replace batteries when the battery indicator shows low power. Use only recommended 9V 6F22 alkaline batteries.
• Coil Protection: Avoid striking the search coil against hard objects.
