Fisher 15" DD Round Open Search Coil for F70, F75 & F75 SE

Description

Cover more ground and search deeper for larger targets with the Fisher 15" DD Round Open Search Coil, designed for the Fisher F70, F75, and F75 Special Edition / SE metal detectors.

This large 15-inch Double-D search coil is built for detectorists who regularly hunt open fields, relic sites, beaches, large properties, and other broad detecting areas where increased ground coverage is a priority.

Its open-frame design helps keep the coil more manageable for its size, while the DD configuration provides versatile performance across different ground conditions.

Key Features

• 15" Search Coil – Large footprint for maximum ground coverage.

• Double-D (DD) Design – Provides broad detection coverage and useful ground handling.

• Round Coil Shape – Designed for efficient searching in open detecting areas.

• Open-Frame Construction – Helps reduce unnecessary material and weight for a coil of this size.

• Designed for Fisher F70, F75 & F75 SE – Compatibility confirmed by current Fisher specialist retailers.

• Ideal for Large Search Areas – Useful for fields, relic sites, beaches, and other open locations.

• Useful for Larger & Deeper Targets – Large coil size is well suited for larger buried objects under suitable conditions.

Compatible Fisher Metal Detectors

This search coil is designed for:

• Fisher F70

• Fisher F75

• Fisher F75 Special Edition / SE

For Detector Warehouse, this listing should stay focused on those three compatible Fisher models.

15" Ground Coverage

The biggest advantage of a 15-inch search coil is the amount of ground it can cover with every sweep.

It is especially useful when searching:

• Open fields

• Large parks

• Farm ground

• Relic sites

• Beaches

• Large properties

• Cache-hunting areas

• Other broad search locations

Compared with a smaller coil, the larger footprint allows more ground to be scanned during each pass.

Double-D Coil Design

This search coil uses a Double-D configuration.

DD coils provide a broad detection pattern and are commonly used in locations where ground conditions can vary.

The 15" DD design makes this coil particularly useful when you want both:

• Broad coverage

• Stable general-purpose ground performance

Round Open-Coil Construction

OK John identifies this product as a 15" DD Round Open Coil.

The open-frame design helps reduce unnecessary mass compared with a fully solid coil of similar size.

That makes the coil more practical for extended sweeping, although a 15-inch coil will naturally feel larger and heavier than standard F70/F75 coils.

Best for Open Hunting Areas

This coil is most useful where there is enough room for long, controlled sweeps.

Good applications include:

• Field detecting

• Relic hunting

• Cache hunting

• Beach detecting

• Large park areas

• Old farm sites

In extremely trashy or confined locations, a smaller coil will usually be easier to maneuver and may provide better target separation.

Deeper & Larger Target Applications

A 15" search coil can offer advantages when searching for larger or deeper targets, particularly in relatively open and clean ground.

OK John specifically positions the coil for deep searches, larger areas, and larger objects.

However, actual detection depth depends on:

• Target size

• Target orientation

• Soil mineralization

• Detector settings

• Sweep speed

• Electromagnetic interference

• Nearby metal

• Ground moisture

For that reason, no exact depth increase should be guaranteed.

F75-Series Performance

Big Boys Hobbies states that this coil is produced by Fisher Labs specifically for the F75 series and highlights its DD construction and relatively lightweight design for a 15-inch coil.

That makes it a natural large-coil option for users who want to extend the capabilities of the F75 platform into broader, more open search areas.
