Introduction
Welcome to the Minelab X-Terra 705 Universal Metal Detector. This device is designed for effective detection of coins, jewelry, relics, and gold nuggets across various ground conditions. This manual provides essential information for assembly, operation, and maintenance to ensure optimal performance and longevity of your detector.
Important Safety Information
- Do not use near airports, power lines, or other sensitive areas.
- Be aware of underground utilities before digging.
- Avoid use in thunderstorms or near water to prevent electrical hazards.
Package Contents
Verify that all the following components are present in your package:
- Minelab X-Terra 705 Control Box
- Search Coil (Double-D, frequency may vary)
- Shaft Assembly (Upper, Middle, Lower sections)
- Armrest with Strap
- Coil Bolt and Washers
- 4 AA Batteries (may be included or required separately)
- User Manual (this document)
Assembly and Initial Setup
1. Attaching the Search Coil
Secure the search coil to the lower shaft using the provided bolt and washers. Ensure the coil cable is wrapped snugly around the shaft to prevent tangling and false signals during operation.

3. Installing Batteries
The X-Terra 705 requires 4 AA batteries. Open the battery compartment, typically located on the control box, and insert the batteries according to the polarity markings (+/-). Close the compartment securely.
Operating Your Detector
1. Powering On and Off
Press and hold the power button (usually marked with a circle and a vertical line) on the control box to turn the detector on or off. The LCD screen will illuminate upon startup.

2. Understanding VFLEX Technology
The X-Terra 705 utilizes Minelab's proprietary True Digital VFLEX technology. This innovative system allows for easy frequency changes by simply swapping compatible coils, enhancing the detector's versatility for different detection conditions and target types.
3. Search Modes
The detector features various search modes optimized for different environments and target types.
Prospecting Mode
This specialized mode offers improved sensitivity to small target signals, making it ideal for highly mineralized areas and searching for small gold nuggets or tiny relics.
4. Ground Balance
Proper ground balance is crucial for stable operation and accurate detection. The X-Terra 705 offers multiple ground balance options:
- Automatic Ground Balance: Automatically adjusts to eliminate false ground noises, allowing for clearer detection of small signals.
- Manual Ground Balance: Allows precise adjustment from 1 to 90 for specific ground conditions.
- Beach Mode: Optimized for wet sand and saltwater environments, reducing interference from conductive ground.
- Tracking: Continuously adjusts ground balance as ground conditions change, providing consistent performance.
Refer to the on-screen prompts or the full manual for detailed steps on performing ground balance.
5. Noise Cancel
Use the noise cancel feature to reduce electromagnetic interference from external sources (e.g., power lines, other detectors), ensuring a stable and clear signal for better target identification.
6. Pinpoint Modes
The detector includes two pinpoint modes to accurately locate targets before digging:
- Auto Pinpoint: Provides a general location of the target with an audio and visual indication.
- Sizing Pinpoint: Offers valuable information on target characteristics, including shape and size, aiding in efficient recovery.
Maintenance and Care
Proper maintenance ensures the longevity and optimal performance of your metal detector:
- Keep the detector clean by wiping it with a damp cloth after each use. Avoid harsh chemicals or abrasive cleaners.
- Store the detector in a dry, cool place away from direct sunlight and extreme temperatures.
- Regularly check all cable connections for wear, damage, or looseness.
- Remove batteries if storing the detector for extended periods to prevent potential leakage and damage to the electronics.
Troubleshooting Common Issues
| Issue | Possible Cause | Solution |
|---|---|---|
| No Power | Dead or incorrectly installed batteries | Replace batteries with fresh ones, check polarity (+/-) |
| Erratic Signals / False Alarms | High mineralization, electromagnetic interference, improper ground balance | Perform ground balance, use noise cancel, reduce sensitivity setting |
| Poor Depth Detection | Incorrect ground balance, low sensitivity, highly mineralized ground | Re-ground balance, increase sensitivity, use Prospecting Mode in difficult areas |
| Detector Not Responding | Loose cable connection, control box issue | Check all cable connections, restart detector. If issue persists, contact support. |
