Military discount on Minelab detectors
The waterproof 17 × 13-inch elliptical Double-D coil provides maximum depth for specialized treasure hunting.
It is also great for wide ground coverage in open spaces.
The Minelab CTX 3030 Carbon Fiber Lower Shaft is a replacement or backup for the shaft that comes standard with the detector.
When you use multiple coils it is great to have it pre-mounted on a shaft for faster switching coils.
