    The Minelab M15 is the 15 x 12 inch elliptical Double-D search coil for the Minelab Manticore. Part number 3011-0423. Minelab describes it as the coil for maximum depth and wide ground coverage in open spaces.

    Who the M15 is for

    The M15 suits Manticore owners who regularly search large open fields, expansive beaches or relatively clean ground where coverage matters. On a broad historical field where good targets may be widely separated, the M15 covers more ground per sweep and may give stronger responses from certain deeper targets.

    How we use the M15

    We fit the M15 when we move from a target-dense site into open ground, particularly when searching for larger or deeper coins and relics. A larger coil may meet more ground mineralization and electrical interference. If the detector becomes noisy, perform Noise Cancel and adjust sensitivity, without automatically increasing it.

    The mistake we see most is treating the M15 as the answer for every deep target. In dense iron, its larger footprint makes nearby targets harder to isolate, and the M8 is the better fit there.

    Key features

    • 15 x 12 inch elliptical footprint: the largest Manticore coil, covering the widest strip per swing.
    • Double-D winding: the winding Minelab uses on all four Manticore coils.
    • Waterproof to 5 m (16 ft): Minelab's rating for the M15, the same as the Manticore detector.
    • 650 g (1.43 lb) with skidplate: Minelab's published weight for the coil with its protective skidplate.
    • 3 year Minelab warranty: Minelab covers Manticore accessories for 3 years.

    How much weight does the Minelab M15 coil add to the Manticore?

    The Minelab M15 coil weighs 650 g (1.43 lb) with its skidplate, Minelab's published figure, which makes it the heaviest of the Manticore coils with a published weight. The Minelab M9 9 inch round coil is the lightest Manticore coil at 366 g (0.81 lb).

    Answered by John W. · September 2026

    Is the Minelab M15 coil a good choice for trashy, iron-heavy sites?

    The Minelab M15 coil is not a good choice for trashy, iron-heavy sites: in dense iron, its larger footprint makes nearby targets harder to isolate. The M15 is built for large open fields, expansive beaches and relatively clean ground where coverage matters. For old homesites, trashy parks and iron-contaminated ground, the Minelab M8 8 x 5.5 inch coil gives better access and target isolation.
