Minelab Manticore M9 Coil Review: Features & Performance

If you're using the Minelab Manticore and want a coil that’s light, fast, and perfect for beach or trashy spots, the M9 9-inch coil might be exactly what you need. In this review, we’ll take a close look at the Minelab M9 coil to help you decide if it’s the right fit for your detecting style.

What Is the Minelab M9 Coil?

The M9 coil is a 9-inch Double D elliptical search coil made for the Minelab Manticore metal detector. It includes a skidplate and is the lightest coil in the Manticore range, weighing only 12.8 ounces.

This coil was built for one thing—speed and precision in tough spots. Whether you’re hunting at the beach or in a park full of trash, the M9 gives you better control without losing depth.

Lightweight and Easy to Swing

One of the biggest benefits of the M9 is how light it is. If you spend hours detecting, you know how much that matters. At only 12.8 oz, the M9 lets you hunt longer without arm fatigue.

This is great for people who have trouble swinging heavier coils or just want a more relaxed experience. Kids and older detectorists will also find it easier to handle.

Built for Tight and Trashy Areas

The M9’s small size gives it a big advantage in crowded spots.

In parks, old house sites, or places full of metal trash, larger coils struggle to tell good targets from junk. The M9 shines here. It separates targets clearly so you don’t waste time digging up bottle caps.

You’ll notice right away how sharp the signals are. Coins, jewelry, and relics stand out even when they’re right next to junk.

Strong Depth for a Small Coil

The M9 holds solid depth for its size. While it won’t go as deep as larger coils on big targets, it still finds coins and small items buried several inches down. That’s plenty for most hunts.

The coil’s Double D design helps it maintain stability and depth, even in mineralized soil or wet sand.

Great for Beach and Water Use

If you detect along shorelines, shallow rivers, or beach surf, you’ll love how this coil moves through the water.

The tight waterproof seal and lightweight frame make it an ideal choice for beach hunters. And since it’s easy to control, you can focus more on finding treasure and less on fighting the waves.

What We Like

• Ultra-lightweight (12.8 oz) for longer hunts
• Excellent target separation in trashy or crowded areas
• Good depth for a 9" coil
• Great control in water
• Fits the Minelab Manticore perfectly
• A Few Limitations
• Smaller coil means less ground coverage

If you're hunting wide open spaces and want to cover ground fast or find deep relics, a larger coil might be better. 

Who Should Use the M9 Coil?

This coil is a great choice for:

• Relic hunters working in iron-rich sites
• Coin shooters who hunt parks and yards

If you already own a Manticore, this coil makes a smart upgrade. It adds versatility and opens up more sites for you to explore.

Customer Feedback

Detectorists who’ve used the M9 often say it quickly became their go-to coil. Most love the balance of speed, comfort, and accuracy. It performs well in places other coils struggle, like near fences or tight wooded spots.

One user mentioned finding several coins in a patch they had already hunted—with a bigger coil. That’s the power of better separation.
