Description
Every Manticore swings in on the same coil, and sooner or later every hard-hunting Manticore needs another one. The M11 is the 11 in (28 cm) round Double-D coil Minelab fits as the Manticore's standard coil, and this is the same coil sold on its own: the straight replacement for a unit that has earned its scars, the spare that keeps a trip alive, or the general-purpose coil you return to after running the specialty sizes.
At a glance: The Minelab M11 (part 3011-0446) is an 11 in / 28 cm round Double-D search coil for the Manticore metal detector, the same model supplied as the Manticore's standard coil. Minelab lists it as a general purpose coil for all treasure hunting, waterproof to 5 m (16 ft). Fits the Manticore only.
The standard coil, verified
This is not our phrasing: Minelab's own Manticore specification sheet prints "Standard Coil: M11 11" Double-D Round." So if you are replacing the coil your Manticore came with, this is the exact part, with no guesswork about geometry or performance changes. It balances sensitivity, depth, and ground coverage across coins, relics, jewelry, beach and gold hunting, which is why Minelab ships the machine with it.
How the M11 fits the Manticore coil range
Run the M11 as your all-round coil, then reach for the M8 sniper in trash-dense or tight sites, the M9 as a compact all-rounder, and the M15 when depth and open-ground coverage are the mission. All four are Manticore-only coils; none fit the Equinox, X-Terra or any other detector.

Frequently asked questions
Is the M11 the coil that comes with the Manticore? Yes. Minelab's Manticore specification sheet lists the M11 11" Double-D Round as the standard coil. Buying this part gets you exactly what shipped on the machine.
Is it waterproof? Yes, submersible to 5 m (16 ft), matching the Manticore's own waterproof rating for diving-depth hunts.
Will it fit my Equinox or X-Terra? No. M-series coils are Manticore-only. Equinox and X-Terra machines use the EQX coil range.

Everyone here detects, top down, for gold, relics, coins and jewelry, and prior field experience is a hiring requirement, not a coincidence. The person answering your coil question may be the one packing your order for the UPS drop-off, and the story is more important than the artifact.
