Designed for the Fisher F75

This search coil is compatible with the:

Fisher F75 Metal Detector

First Texas lists the 12COILDD-F75 as a compatible accessory within its official F75 parts and accessories catalog.

For Detector Warehouse, this product is specifically positioned for Fisher F75 owners.

Larger 12" Ground Coverage

The 12-inch footprint is designed for detectorists who want to cover larger areas efficiently.

It can be particularly useful when searching:

• Open fields

• Parks

• Large yards

• Relic sites

• Old properties

• Farm fields

• Other broad detecting locations

With a larger search area under the coil, you can efficiently scan open ground without relying on an oversized aftermarket accessory.

Double-D Search Coil Design

This search coil uses a Double-D (DD) configuration.

DD coils are commonly chosen for their useful ground handling across changing or mineralized soil conditions.

For F75 users, this makes the 12" coil a versatile option when searching locations where both coverage and ground handling matter.

Triangulated Bi-Axial Configuration

The coil uses a Triangulated Bi-Axial design, distinguishing it from conventional round or smaller elliptical Fisher search coils.

The configuration provides a broad search footprint while retaining a defined forward section that can help with coil placement during target investigation.

It is particularly suited to F75 users who want a larger search option without moving to an unrelated aftermarket coil platform.

Built for Open-Site Detecting

The 12" size makes this coil particularly attractive for hunts where there is plenty of room to sweep.

Good applications include:

• Relic hunting

• Coin hunting

• Field detecting

• Jewelry hunting

• Old home sites

• General treasure hunting

In highly congested or target-dense locations, a smaller Fisher coil may provide easier maneuverability and separation.

Performance Expectations

A larger search coil can provide greater ground coverage and may offer advantages on certain larger or deeper targets under suitable conditions.

However, detecting depth is not fixed.

Actual performance depends on:

• Target size

• Target orientation

• Ground mineralization

• Detector settings

• Sweep speed

• Electromagnetic interference

• Nearby metal objects

• Soil moisture and conditions

For that reason, no specific depth claim should be expected from the coil in every hunting environment.

Matching Coil Cover

First Texas identifies 12COVER-DD as compatible with the 12COILDD-F75.

The protective cover helps shield the bottom of the search coil against scratches, scuffs, and routine ground contact.

The coil cover is sold separately unless specifically included with the offer.

Why Choose the Fisher 12" DD Coil for Your F75?

When you're searching a large area, ground coverage matters.

Its 12-inch size, DD configuration, and Triangulated Bi-Axial design make it a useful larger-coil option for F75 owners who want a genuine Fisher accessory rather than a generic aftermarket search coil.

Most importantly, First Texas officially lists this exact coil as compatible with the Fisher F75, helping remove uncertainty when choosing the correct accessory for your detector.
