Minelab M9 9" DD Waterproof Coil for Manticore Metal Detector

When your Manticore's 11-inch coil loses ground in dense trash or tight terrain, the Minelab Manticore M9 coil is what our team recommends first. This 9-inch round Double-D is built exclusively for the Minelab Manticore, delivers the detector's full Multi-IQ+ capability, and at 362g with the skidplate it is the lightest option in the Minelab coil lineup. It is the right upgrade for detectorists who want the Manticore's exceptional 2D Target ID in spots where a larger coil will not fit or perform.

What's Included

• Minelab M9 9" round Double-D coil
• Protective skidplate (pre-fitted; included in the 362g weight spec)

Why You Need the M9 in Your Arsenal

• Lightest Manticore coil at 362g with skidplate: The swing-weight reduction is real and noticeable after hour three of a full-day hunt in parks, fields, or along the water's edge.
• 9-inch round footprint sharpens target separation: The tighter coverage area helps the Manticore pull apart stacked signals in moderate to heavy trash more cleanly than the standard 11-inch coil.
• Low profile threads through tight terrain: Sweeps through brush, root-heavy woodlots, and shallow water where a larger coil snags or loses ground contact.
• Waterproof to 5m (16ft): Fully submersible for wading, surf hunting, and beach detecting without any additional housing or protection.
• Full Multi-IQ+ compatibility: Every detection mode, 2D Target ID display, and custom profile on your Manticore transfers directly to the M9 without compromise.

Where the Minelab Manticore M9 Coil Excels in the Field

Trashy Parks and Coin-Dense Sites

The 9-inch round footprint keeps target separation tight in the sites that frustrate larger coils most. Old parks, schoolyards, and fairgrounds with stacked coins and iron benefit from the narrower swing arc, which lets the Manticore's 2D Target ID resolve individual targets before adjacent iron smears the reading. Running Field mode or a custom Ferrous Limits profile, you will pull dimes and rings out of mixed trash that the 11-inch coil would blur. For a detailed breakdown of how the M9 handles trash versus the compact M8, our Manticore M8 vs M9 comparison guide covers the real-world tradeoffs.

Beach and Shallow-Water Detecting

With a 5m waterproof rating and the lowest swing weight in the Manticore range, the M9 is a natural fit for wading the surf line or hunting wet sand on a falling tide. The round format delivers consistent coverage on irregular sand terrain, and the lighter coil reduces fatigue across a full tidal session. For deep black-sand beach work where ground mineralization demands maximum signal penetration, the larger M15 is the better tool. For the wash zone, shallow surf wading, and moderate wet-sand conditions, the M9 covers it cleanly.
