XP 13x11" FMF Search Coil for XP Deus II

Some permissions are measured in acres, not corners. When the field runs to the tree line and the good targets sit deep, coil size becomes the whole argument. The XP 13x11 in (34x28 cm) FMF search coil is the depth and coverage option for the XP Deus II: the coil you mount when you want to reach further and clear ground faster than any smaller coil can.

At a glance

The XP 13x11 in (34x28 cm) FMF search coil for the XP Deus II is an elliptical Double-D running 49 frequencies from 4 to 45 kHz. 570 g / 20.1 oz, fully waterproof to 20 m (66 ft), wireless with up to 20 hours of runtime. Includes coil cover, screwing kit, and lower stem. Built for maximum depth and coverage on open ground. 5 year XP warranty.

What the 13x11 in coil is for

A larger coil pushes a bigger detection field into the ground and sweeps a wider path, so deep, high-mass targets get a real chance to answer and you cover open acreage in fewer swings. This is the coil for big farm fields and pasture permissions, wide beach flats, and the deep relic and coin work where a mid-sized coil runs out of reach before the target does. The elliptical 13x11 shape keeps it manageable and helps it thread between obstacles better than a full round coil of the same footprint.

It is a specialist, and we would rather say so: in tight, iron-choked ground a big coil is heavier on the arm and blurs targets packed close together. For trashy home sites and nail beds, stay with the 9 in. The 13x11 in earns its place on open, workable ground where depth and coverage win the day.

FMF, and fully waterproof

This is a Fast Multi Frequency (FMF) coil: it runs up to 49 frequencies from 4 to 45 kHz, either as simultaneous multi-frequency or as a single chosen frequency, the technology that keeps the Deus II stable in salt and sharp across coins, relics, and gold. The coil is wireless, with its own battery built into the coil, and it is fully waterproof to 20 m (66 ft), so wading, surf, and shallow diving are all in bounds, not just a splash rating.

Technical Specifications

Which Deus II coil is right for you

The 9 in is the separation and finesse coil for tight, trashy, iron-heavy ground. The 11 in is the all-rounder that balances depth and separation for most sites. The 13x11 in is the depth and coverage coil for open fields and deep relics. Not sure which fits your ground? Call us and we will talk through where you hunt.

Frequently Asked Questions

Which detector does this coil fit?

The XP Deus II. It is also compatible with the XP Icon and Icon X, which run the same FMF platform. It is not compatible with the original XP Deus (Deus I).

Is this coil compatible with the original XP Deus (Deus I)?

No. This is an FMF coil for the Deus II platform and it is not compatible with the original XP Deus, usually called the Deus I. Deus I owners need X35 or HF series coils instead.

Is the XP 13x11 in FMF coil (D3428FMF) compatible with the XP Icon or Icon X?

Yes. The 13x11 in FMF coil is compatible with both the XP Icon and Icon X.

Can I use this coil on my XP Deus II Gold?

Yes, the coil works with the Deus II Gold. One thing to know before you order: the charging clip that ships with the Deus II Gold will NOT fit this coil, so add the separate XP charging clip for FMF coils.

Does it come with a charging clip or charger?

No, a charger is not included. It uses the same charging system as XP detectors that shipped with a 9 in, 11 in, or 13x11 in FMF coil, so if your Deus II came with one of those, your existing charger works. The XP Deus II Gold charger will NOT work with this coil.

Does this coil come with the lower shaft?

Yes. A lower shaft (lower stem) is included free in the box, along with the screwing kit that fastens the coil to it.

Does it come with a coil cover?

Yes. A coil cover is included and comes already attached to the coil.

Does the coil have its own battery?

Yes. The battery is built into the coil itself, rated for up to 20 hours depending on programs and frequencies, and the coil connects to your detector wirelessly with no coil cable.

Is the 13x11 in coil waterproof?

Yes, fully submersible to 20 m (66 ft), so it is fine for wading, surf, and shallow diving, not just rain.

How much extra depth does the 13x11 in give?

Depth gains depend on soil, target size, and how the target sits, so an exact figure is a guess. The biggest gains show up on larger, deeper targets in clean, open ground, where the bigger field reaches past what a mid-sized coil can. On small, shallow targets in trash, a smaller coil is often the better tool.

Does it come with everything I need to run it?

For mounting and hunting, yes: the coil with its cover already attached, the screwing kit, and the lower stem. A charging clip is not included, so plan on your existing FMF charger or add the separate charging clip.

How do I pair the coil with my Deus II?

Pair it once from the coil pairing menu on your remote or WS6 headphones and the machine remembers it. Switching between paired coils takes a few seconds in the field.
