When your Minelab Equinox starts displaying error codes, it's trying to tell you exactly what's wrong. These diagnostic codes appear on the Target ID Display and help you quickly identify and fix common detector issues without a trip to the repair shop.
The Equinox 600 and 800 models use a simple error code system that makes troubleshooting straightforward. Understanding these codes can save you hunting time and prevent minor issues from becoming major problems.
Common Minelab Equinox 800 Problems: Error Code Overview
The Equinox series displays three main error types, each with specific diagnostic steps. These codes appear when the detector's self-diagnostic system detects hardware or connection issues.
Error Code: Co (Coil Disconnected)
This is the most common error you'll encounter. The "Co" code appears when the control unit can't communicate with the search coil.
Recommended Action
- Check that the coil connector is connected properly at the back of the control unit.
- Check the coil cable for damage, kinks, or wear spots near the connector.
- Check the coil for visible signs of damage, especially around the cable entry point.
- Try another coil, if you have one available - this isolates whether the issue is with the coil or control unit.
If the problem persists with multiple coils, the issue is likely with the control unit's coil connector port and requires professional service.
Error Code: bE (Critically Low Battery)
The "bE" code warns you that the internal battery has reached critically low levels and the detector will shut down soon.
Recommended Action
- Recharge the battery immediately using the included USB charging cable.
- Connect a USB power bank for extended hunting sessions.
- Contact an Authorised Service Centre to replace the internal battery if it won't hold a charge.
Pro tip: The Equinox typically provides 2-3 hours of warning before complete shutdown, giving you time to finish your hunt or return to your vehicle.
Error Code: Er (System Error)
System errors are the most serious, indicating internal software or hardware malfunctions. The "Er" code appears with an accompanying number on the Frequency Display.
Recommended Action
- Note the error code number shown on the Frequency Display - this helps service technicians diagnose the specific issue.
- Restart the detector to determine if the error still remains.
- Confirm the coil is attached correctly and cables aren't damaged.
- If the error persists, perform a factory reset by pressing and holding the Power button for 5 seconds.
- If the error still remains, please return the detector to your nearest Authorised Service Centre for repair.
The detector will automatically shut down 5 seconds after displaying a system error to prevent potential damage.
Preventing Common Equinox Problems
Most Equinox error codes result from preventable issues. Regular maintenance keeps your treasure hunting equipment running smoothly:
- Coil Care: Rinse saltwater off coils after beach hunting and inspect cables monthly for wear
- Connection Maintenance: Keep coil connectors clean and dry - moisture causes intermittent "Co" errors
- Battery Health: Charge regularly and avoid complete discharge cycles
- Firmware Updates: Keep your detector updated through Minelab's software when available
When to Seek Professional Help
While many error codes resolve with basic troubleshooting, some situations require professional service:
- Repeated "Er" system errors with different error numbers
- "Co" errors that persist with multiple known-good coils
- Battery errors when the battery is new or recently serviced
- Physical damage to connectors or internal components
Consider investing in backup accessories like spare coils or battery packs to minimize downtime during your detecting adventures.
