Minelab 15 x 12" M15 DD Waterproof Coil for Manticore Metal Detector

The Minelab M15 is a 15 x 12-inch elliptical Double-D waterproof search coil engineered exclusively for the Manticore, delivering the largest detection footprint Minelab offers for the platform. Manticore owners working expansive agricultural fields, lightly hunted pastures, or wide-open beach stretches reach for the M15 when ground coverage and depth matter more than pinpoint target separation in tight trash. Where the stock 11-inch coil balances versatility and maneuverability, the M15 prioritizes raw reach and sweep efficiency on sites where targets sit deep and spacing allows a wider swing path.

What's Included with the M15

• Minelab M15 15 x 12-inch Double-D waterproof search coil for Manticore
• Fitted skidplate (pre-installed)

Why Manticore Owners Reach for the M15

• Genuine depth gains on open, clean ground. The larger footprint reaches targets the stock coil misses below the typical coin-depth ceiling, giving the Manticore a measurable advantage on underhunted agricultural land and lightly detected fields.
• Cover significantly more ground per sweep. The wider swing path lets you work a large site faster, and on expansive beach stretches or open fields, ground coverage is how you find more targets in a session without hunting longer.
• Waterproof to 16 feet. The M15 runs in dry sand, wet sand, and the surf line with no coil swap needed, rated for full submersion to 5 meters.
• Full Multi-IQ+ and 2D Target ID carry through unchanged. Switching to the M15 does not compromise the Manticore's target intelligence, and the 2D display gives accurate tone and VDI readings even on deep signals.
• Skidplate included from day one, so the coil face is protected on your first hunt.

Deeper Coverage and Faster Ground Clearing on Open Sites

Agricultural Fields and Pastures

On agricultural fields, pastures, and open estate grounds with relatively low mineralization, the M15 changes what the Manticore can reach. The wider sweep covers more area per pass, and targets sitting deep become consistently reachable. Raise Recovery Speed one or two steps above your usual field setting to manage any additional noise from the larger coil area.

Beach Hunting in Open Surf and Dry Sand

Waterproof to 5 meters, the M15 is just as capable in the surf and shallow water as it is across dry sand. On wide, open beach sites that have not been worked to exhaustion, the coverage advantage lets you cover productive stretches faster than a smaller coil allows. Beach Mode handles saltwater ground balance automatically. If you move into a section with heavier iron or tighter target spacing, the M9 is the right tool for that transition.

Large Historical Sites with Deep Undisturbed Material

On lightly hunted parks, commons, and former estate grounds where deep material has gone untouched for years, the M15's depth advantage matters most. These are the sites where targets at depth are reachable with the right coil, and covering the full footprint efficiently matters as much as raw sensitivity. Understanding how the technologies behind modern detectors process signals from larger coils helps you optimize settings for maximum performance.

How it compares to other Manticore coils

The M15 sits at the top of the Manticore coil lineup for ground coverage and depth, while the M8 and M9 prioritize target separation and maneuverability. Each coil is built for a specific detecting scenario.
