Minelab Z18 18" Concentric Toroidal Coil for GPZ 8000

The Minelab Z18 18 in Concentric Toroidal Coil is the deep-seeking flagship of the GPZ 8000 Z-Set coil range, engineered for maximum depth and stability in highly mineralized ground. Its large 18 in footprint drives deeper penetration to reach medium to large gold while efficiently covering wide open country, with reduced ground noise that keeps faint deep signals readable.

The Z18 is the largest coil in Minelab's Z-Set Concentric Toroidal range, which also includes the Z13 13 in and the Z17 17 in. Where the compact Z13 chases maneuverability on small gold and the Z17 tames noisy, EMI-heavy ground, the Z18 is purpose-built for depth and coverage. It is the coil to reach for when you want to pull the deepest, biggest targets out of mineralized dirt. Browse the full Minelab GPZ 8000 range to see how the three Z-Set coils compare.

Designed specifically for the Minelab GPZ 8000, Minelab's flagship gold detector powered by GeoZVT technology, the Z18 ships as the standard coil on the single coil pack. Its concentric toroidal winding suppresses ground noise so deep target response stays clear where a conventional coil would struggle. The whole detector weighs 2.78 kg (6.1 lbs) with the Z18 fitted, so the extra size does not cost you a workable swing weight.

If you work open, highly mineralized ground, chase deep medium to large nuggets, or want to expand your coverage and reach deeper soil layers, the Z18 is the ideal match for your GPZ 8000. Pair it with the matching Z18 coil cover skidplate to protect the underside on abrasive ground.

Key Features

Is the Z18 the Right Coil for Your Ground?

Coil choice on a GPZ 8000 comes down to target size and ground condition. Go with the Z18 when you are working open, deep, highly mineralized ground and hunting medium to large nuggets, and step down in size when the gold is small or the patch is tight and brushy.
