Who Is the XP Deus II 13x11" Coil Best For?
The 13x11" FMF coil is a great choice for Deus II users who hunt larger, more open sites and want to cover ground faster than they can with the smaller 9" or 11" coils. It is especially useful for:
- Open fields and pasture hunting
- Relic hunting sites
- Beach hunting and wet sand searching
- Large parks and fairgrounds
- Covering more ground with fewer sweeps
- Searching for deeper coins, relics, and larger targets
If you hunt tight iron, heavy trash, or small confined areas, a smaller coil may still be the better choice. But when coverage and depth are your priority, the XP Deus II 13x11" FMF coil is one of the best upgrades you can add to your Deus II setup.
XP FMF Multi-Frequency Performance
This coil uses XP’s FMF® Fast and Simultaneous Multi Frequency platform, giving your Deus II the ability to run advanced multi-frequency programs or single-frequency options from 4 kHz to 45 kHz. Lower frequencies can be helpful for larger and deeper targets, while higher frequencies can improve sensitivity to smaller targets and low conductors.
That flexibility is one of the biggest reasons the Deus II platform is so popular. Whether you are hunting old coins, Civil War relics, jewelry, beach targets, or general treasure, this coil gives you a wide range of performance options.

13x11" Coil vs. Smaller Deus II Coils
The XP Deus II is compatible with multiple FMF coil sizes, including the 9", 11", and 13x11" coils. Each coil has its place:
- 9" FMF Coil: Best for tight trash, iron, target separation, and lighter swing weight.
- 11" FMF Coil: A strong all-around choice for general detecting.
- 13x11" FMF Coil: Best for more ground coverage, open areas, beach hunting, pasture, and larger search areas.
If you already own a Deus II and want to expand what it can do, adding the 13x11" coil gives you a larger coverage option without buying a whole new detector.
Bart’s Take
If you mainly hunt open fields, beaches, pasture, or big relic sites, the XP Deus II 13x11" FMF coil is a smart upgrade. It lets you cover ground faster and can give you an advantage when you are trying to locate deeper or wider-spread targets. For heavy iron or tight trash, I still like a smaller coil, but for open ground, this big Deus II coil earns its place.
