    The Minelab GM05 is the 5 inch round Double-D search coil supplied as standard on the Minelab Gold Monster 1000. Part number 3011-0337. Minelab describes it as the coil for the prospector who needs precision, and a replacement GM05 puts a Gold Monster 1000 back in its factory configuration.

    Who the GM05 is for

    The GM05 suits prospectors who search bedrock cracks, rocky hillsides, narrow crevices and spots where very small gold may be present. Around exposed bedrock, the 5 inch coil fits into places a larger coil cannot reach. Gold Monster 1000 owners who have damaged, worn or lost the original coil get the exact coil the detector ships with.

    How we use the GM05

    We pick the GM05 over the GM 10 when detailed searching and access to small targets matter more than covering ground quickly. Keep the coil close to the surface and use slow, overlapping sweeps. When you move between noticeably different ground, give the detector's automatic ground balance a moment to settle.

    The mistake we see most is buying the wrong coil for the detector. The GM05 is a Gold Monster 1000 coil and does not fit the Gold Monster 2000.

    Key features

    • 5 inch (13 cm) round footprint: a small coil that fits into tight spots between rocks, roots and bedrock edges.
    • Double-D winding: the same winding Minelab uses on the GM 10, the other Gold Monster 1000 coil.
    • Waterproof to 1 m (3.3 ft): Minelab's rating for the GM05 coil, so the coil can work shallow creek edges and wet gravel.
    • Standard Gold Monster 1000 coil: the coil Minelab supplies on the Gold Monster 1000 with 5 inch coil.
    • 2 year Minelab warranty: Minelab covers Gold Monster accessories for 2 years.

    Compatibility

    Minelab lists two coils for the Gold Monster 1000: the GM05 and the GM 10 10 x 6 inch Double-D. The Minelab Gold Monster 2000 has its own 5 inch coil, the GM2000-05 (part 3011-0526), listed in that collection. Gold Monster 1000 and Gold Monster 2000 coils are not interchangeable.

    The GM05 suits tight, rocky ground and close target spacing. The GM 10 suits open gravel, open hillsides and dry washes, but a bigger coil is not automatically better when physical access is the limit.

    Both Gold Monster 1000 coils are in our metal detector search coils collection. Comparing detectors before buying a spare coil? Our Gold Monster 1000 vs 2000 comparison covers what changed between the two, and our metal detecting tips cover technique.
