Garrett Axiom 11 x 7 in DD-FC Search Coil
The Garrett Axiom 11 x 7 in DD-FC search coil is the compact coil for the Garrett Axiom pulse induction gold detector, set up for the smallest gold and the tightest ground. The small footprint reacts to sub gram pickers that larger coils sweep past, and it threads through brush, rock piles and creek edges where a big coil cannot reach.
Even at this size it keeps the DD-FC advantages. The Double-D winding and centralized Focused Core hold stability in mineralized soil and separate close targets, and DD-FC lets the Axiom run Iron Check for a tone based read on iron. The trade for the extra sensitivity and handling is ground coverage and outright depth, which the larger coils provide.
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
Sensitive to the Smallest Gold
The compact 11 x 7 in coil reacts to sub gram pickers and fine gold that wider coils pass over. The Focused Core keeps it stable in hot ground while it hunts the smallest targets.

Gets Into Tight Ground
The small footprint threads through brush, rock piles and creek edges that block a larger coil. It is the coil for working patches that have already been hit and ground where access is tight.
Iron Check Tone ID
Because it is a DD-FC coil, it enables the Axiom Iron Check feature for a tone based read on iron, and it separates close targets cleanly. That helps you sort small gold from ferrous trash before you dig.
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: What is the 11 x 7 in DD-FC coil good for?
A: It is the compact coil for the smallest gold and tight ground. It reaches sub gram pickers and threads through brush and rocks where larger coils cannot swing.
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 13 x 11 in and 16 x 14 in coils?
A: The 11 x 7 in is the most sensitive to tiny gold and the easiest to handle, but it covers less ground and reaches less deep. The 13 x 11 in balances both and the 16 x 14 in covers the most ground and goes deepest.
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.
