XP - 13" x 11" FMF Wireless Search Coil: 

 

The XP D3428FMF 13" x 11" FMF Wireless Search Coil is the large-format option in XP's standard FMF coil lineup, designed for detectorists who want maximum ground coverage, excellent depth, and outstanding performance across large open areas.

Measuring approximately 13" x 11" / 34 x 28 cm, the D3428FMF uses XP's advanced FMF® Fast and Simultaneous Multi-Frequency technology, providing simultaneous multi-frequency performance along with 49 selectable single frequencies ranging from 4 to 45 kHz on compatible systems.

Its larger footprint allows you to cover more ground with every sweep, making the D3428FMF an excellent choice for beaches, farm fields, pastures, open relic sites, large parks, and other expansive detecting locations.

FMF® Fast & Simultaneous Multi-Frequency Technology

The D3428FMF utilizes XP's advanced FMF – Fast and Simultaneous Multi-Frequency technology.

FMF allows compatible XP detectors to process multiple frequencies simultaneously, providing strong performance across a broad spectrum of target sizes, conductivities, and ground conditions.

The coil also provides access to:

49 selectable single frequencies from 4 to 45 kHz

on compatible XP platforms.

This broad frequency range gives detectorists excellent versatility when searching for everything from larger high-conductive coins and relics to smaller jewelry and lower-conductive targets.

Large 13" x 11" / 34 x 28 cm Design

The D3428FMF measures approximately:

13" x 11" / 34 x 28 cm

The larger footprint is designed to provide greater ground coverage than XP's 9" and 11" FMF coils.

This makes the D3428FMF particularly effective when searching large areas where covering ground efficiently is a priority.

Maximum Ground Coverage

One of the biggest advantages of the D3428FMF is the amount of ground it covers with each sweep.

This makes it an excellent choice for:

• Large farm fields

• Beaches

• Pastures

• Open parks

• Large relic sites

• Historic fields

• Open mining areas

• Large properties

• Competition hunts

• General prospecting and treasure hunting

When targets are spread across a large area, the D3428FMF allows you to search more efficiently than a smaller coil.

Excellent Depth Performance

The larger coil footprint also provides excellent performance when searching for deeper targets.

The D3428FMF is particularly useful when searching relatively open ground where desirable targets may be located beyond the easiest detection range of smaller coils.

Potential deep targets include:

• Coins

• Relics

• Larger jewelry

• Military artifacts

• Buttons

• Buckles

• Tokens

• Larger metallic objects

Actual detection depth will vary considerably based on target size, orientation, ground mineralization, detector settings, and environmental conditions.

Excellent for Field & Relic Hunting

The D3428FMF is particularly well suited for large historic sites.

Farm fields, old gathering places, military sites, mining areas, and abandoned settlements can cover enormous amounts of ground.

The larger coil allows relic hunters to search these areas efficiently while retaining XP's FMF performance.

Excellent applications include:

• Old farm fields

• Historic settlements

• Mining camps

• Military sites

• Ghost towns

• Homesteads

• Old trails

• Large relic fields

• Fairgrounds

• Gathering places

Excellent for Beach Detecting

The 13" x 11" footprint makes the D3428FMF an excellent beach-searching coil.

Large beaches require enormous amounts of ground coverage, and every additional inch of coil coverage can help you search more efficiently.

Combined with XP's FMF beach programs, the D3428FMF is well suited for:

• Dry sand

• Wet sand

• Saltwater beaches

• Freshwater beaches

• Surf hunting

• Shallow water

• Underwater detecting

The larger footprint makes it particularly attractive for searching long stretches of relatively open beach.

Excellent for Open Terrain

The D3428FMF performs best where its larger physical size can be used effectively.

It's an excellent choice for:

• Open fields

• Beaches

• Pastures

• Large parks

• Open woods

• Large historic properties

• Relatively clean ground

For extremely tight areas, dense iron, heavy brush, or locations containing large amounts of closely spaced trash, XP's smaller 9" or 11" FMF coils may provide greater maneuverability and target separation.

Wireless FMF Technology

Like XP's other FMF coils, the D3428FMF is a fully wireless search coil.

The coil contains its own:

• Detection electronics

• Wireless communication system

• Rechargeable lithium battery

There is no conventional coil cable running up the detector shaft.

The coil communicates wirelessly with the compatible XP controller, helping maintain the clean, lightweight, cable-free design XP detectors are known for.

Rechargeable Internal Battery

The D3428FMF contains an integrated rechargeable lithium battery.

XP rates battery life at up to approximately:

20 hours

depending on the program and frequencies being used.

This provides enough runtime for extended detecting sessions without disposable batteries.

Fully Waterproof to 20 Meters / 66 Feet

The D3428FMF is:

Fully waterproof to 20 meters / 66 feet

This makes the coil suitable for:

• Underwater detecting

• Beaches

• Rivers

• Lakes

• Creeks

• Surf hunting

• Swimming holes

• Wet environments

• Freshwater

• Saltwater

Because XP coils communicate wirelessly, the appropriate XP underwater antenna/waveguide configuration may be required when the detector is submerged.

Weight

The D3428FMF weighs approximately:

570 grams / 20.1 oz

The larger coil is heavier than XP's 9" and 11" FMF options, but the additional size provides increased ground coverage for detectorists working large open areas.

Product Compatibility

The XP D3428FMF is part of XP's modern FMF search-coil ecosystem.

Compatible With

• XP DEUS II

• XP DEUS II Remote Control

• XP WS6 Master

• XP WS6 ST Master

• XP ICON

• XP ICON X

XP DEUS II

The D3428FMF is designed for the XP DEUS II and provides access to the detector's advanced FMF programs and controls when paired with the DEUS II Remote.

This combination is an excellent choice for detectorists searching large fields, beaches, and relic sites.

XP WS6 Master

The D3428FMF can also be paired with an XP WS6 operating in Master mode.

The WS6 communicates with and controls the search coil, allowing you to operate without the full DEUS II Remote Control.

XP WS6 ST Master

The newer XP WS6 ST can also function as the master controller for the D3428FMF.

This allows you to combine the large 13" x 11" coil with XP's compact WS6 ST controller for a streamlined detector configuration.

XP ICON & ICON X

The D3428FMF is also compatible with the newer XP ICON and ICON X.

XP officially lists the D3428FMF 34 x 28 cm / 13" x 11" among the DEUS II FMF ecosystem coils supported by ICON and ICON X.

This allows the same D3428FMF coil to be used across multiple compatible XP FMF detector platforms.
