Description
The Minelab Manticore M15 Search Coil is a high-performance, deep-seeking accessory engineered to maximize ground coverage and target depth. Built as a 15 x 12-inch (38 x 30 cm) elliptical Double-D (DD) smart coil, this loop pushes the electronic capabilities of the Manticore platform to its upper technical limits. It is the ultimate choice for locating deeply buried coin caches, historical hoards, large military relics, and artillery projectiles that lie far below the reach of standard-sized detection fields.
At History Seekers, we operate on the principle that the story is more important than the artifact. To uncover the deepest chapters of history on your permissions, the M15 provides the critical depth headroom needed to bring older, heavily hunted sites back to life, punching right through old tracks to find the targets standard loops miss entirely.
Key Performance Advantages
- Maximum Depth Headroom: The large 15 x 12-inch (38 x 30 cm) footprint generates a massive electromagnetic field cone, delivering superior depth penetration on high-mass targets. The performance advantage is exceptional on larger items buried deep in clean pasture or agricultural grids.
- Breathing New Life into Pounded Sites: When a premier permission has been cleared of its shallow and mid-depth targets by standard-sized loops, mounting the M15 lets you search deeper to uncover the oldest, deepest keepers left behind.
- Efficient Acreage Coverage: The 15-inch (38 cm) sweep width covers significantly more ground per swing than stock loops. This maximizes your field efficiency on wide open fields, large agricultural tracts, and open beach flats where your hunting window is limited.
- Low-Profile Water Drag Reduction: The skeleton DD design minimizes water resistance. In shallow surf zones, tidal flats, and river wading, water flows directly through the frame rather than pushing against it, reducing fatigue and keeping your sweep flat. It carries a full IP68 waterproof rating up to 16 feet (5 meters).
Field Deployment Tips
The M15 search coil is optimized for open ground, beach flats, large fields, and deep relic hunting. Because of its large field diameter, it is best utilized on sites with low-to-moderate trash density. For areas packed with dense iron trash or tightly clustered nails, such as old cellar holes, a more compact footprint like the M9 search coil (9 inches / 23 cm) will offer better isolation. Carrying both gives you the ultimate full-site deployment strategy.

Frequently Asked Questions
How much extra depth does the M15 provide over the stock M11 loop?
Depth gains vary with soil conditions and target size. On standard coin-sized targets in average dirt, the M15 provides an extra 1 to 2 inches (2.5 to 5 cm) of depth. However, the true advantage opens up on high-mass targets. For objects larger than 3 inches (7.6 cm) in diameter, including artillery shells, hoards, and deep iron caches, the M15 can punch an additional 3 to 4 inches (7.6 to 10 cm) deeper than the standard M11 11-inch (28 cm) loop.
Is the M15 significantly heavier than the stock loop?
The standard M11 11-inch (28 cm) loop weighs 15.3 ounces (434 grams), while the large M15 weighs 22.9 ounces (650 grams). This means the M15 is only 7.6 ounces (216 grams) heavier than the stock loop. While the carbon fiber shaft balances this weight beautifully, using a support harness or bungee system can help maintain a level, consistent sweep speed during long multi-hour hunts.
Does it require any special settings or software updates?
No. The Manticore features automatic smart coil recognition. When you attach the M15 search coil and power on the control pod, the machine instantly identifies the 15 x 12-inch (38 x 30 cm) framework and optimizes its internal signal calibrations automatically. No manual reconfiguration is required.
