Minelab Equinox 900 with EQX 11 and EQX 6 Coils

Multi-frequency detection system

The Minelab Equinox 900 combines simultaneous multi-frequency technology with two Double-D coils to serve detectorists who need one machine for every soil type. The EQX 11 and EQX 6 coils extend coverage from wide-area scanning to precise target separation in trashy ground.

Frequency flexibility and soil limits

Six selectable single frequencies let the operator tune for specific conductivity targets, while the multi-frequency mode handles mineralised beaches and parks without manual re-balancing. Highly conductive or deeply buried objects may still fall outside the effective detection envelope of the supplied coils.

Coil swapping and common pitfalls

Both coils attach via the standard Equinox mount, so changing between the 11-inch and 6-inch heads takes seconds without tools. The most frequent issue is forgetting to run the ground-balance routine after a coil change, which leaves target IDs drifting in mineralised soil.
