Garrett Axiom 13 x 11 in DD-FC Search Coil
The Garrett Axiom 13 x 11 in DD-FC search coil is the mid size, all purpose coil for the Garrett Axiom pulse induction gold detector. It balances depth, ground coverage and handling, which is why it is the coil many prospectors leave on the machine for everyday hunting. It is also the DD-FC coil that ships in the Axiom standard package.
The Double-D winding and centralized Focused Core hold detection depth in mineralized soil and separate close targets, while DD-FC lets the Axiom run Iron Check for a tone based read on iron. The 13 x 11 in size swings easily through brush and broken ground without giving up much depth, so it reads small gold and deeper targets alike.
The coil is fully waterproof and ships with a snap on cover that protects the bottom from rock and abrasion. It fits the Garrett Axiom and carries Garrett's 3 year limited warranty.

Features
Focused Core in an All Purpose Size
The centralized Focused Core concentrates the field so the 13 x 11 in DD-FC holds depth and stays stable in mineralized soil. The mid size footprint makes it the coil to run for general prospecting where you want depth without losing handling.

Iron Check Tone ID
As a DD-FC coil it enables the Axiom Iron Check feature, giving a tone based read on iron so you can pass ferrous trash before digging. It also separates targets that sit close together, which mono coils struggle to do.
Balanced Depth and Coverage
At 13 x 11 in the coil reaches deep enough for most patches while staying nimble in brush and broken ground. It is a strong everyday choice between the wide 16 x 14 in and the sensitive 11 x 7 in coils.
Waterproof and Built for the Garrett Axiom
The coil is fully waterproof and submersible for wet ground, creek edges and shallow water. It is designed for the Garrett Axiom and connects directly with no adapter.

FAQ
Q: Is the 13 x 11 in DD-FC a good all around coil?
A: Yes. It balances depth, coverage and handling, which makes it a strong everyday coil for the Garrett Axiom. It is also the DD-FC coil included in the Axiom standard package.
Q: What is the difference between a DD-FC and a Mono coil?
A: A DD-FC coil uses a Focused Core to hold depth in mineralized ground, separates close targets and supports the Axiom Iron Check tone ID. A Mono coil goes for maximum depth and small gold sensitivity but gives no iron ID.
Q: How does it compare to the 16 x 14 in and 11 x 7 in coils?
A: The 13 x 11 in sits in the middle. The 16 x 14 in covers more ground and reaches deeper, while the 11 x 7 in is more sensitive to tiny gold and handles better in tight spots.
Q: Is the coil waterproof?
A: Yes. The coil is fully waterproof and submersible. The Axiom control housing is not submersible, so keep the control box dry.
Q: Does it come with a coil cover?
A: Yes. A snap on coil cover is included to protect the bottom of the coil from rock and abrasion.
