Minelab 11 inch DD Search Coil for CTX 3030 Metal Detector with Coil Cover

The Minelab 11-inch DD coil is waterproof and submersible to 10 feet (3 meters), making it suitable for surf hunting, river wading, and shallow-water detecting. The coil's sealed construction handles saltwater and freshwater environments without signal drift or coil failure. CTX 3030 operators working Gulf Coast beaches and Appalachian streams rely on this waterproof rating to hunt chest-deep in moving water and mineralized wet sand. The included skidplate protects the coil face from rocks and roots during wading sessions.

The Minelab 11-inch DD coil ships with a protective skidplate, coil cover, and coil hardware kit for direct installation on the CTX 3030. The skidplate guards the coil face against abrasion in rocky sites and shell beds, while the coil cover prevents scratches during transport and storage. The hardware kit includes the mounting bolts and washers needed to attach the coil to the CTX 3030's lower rod. No additional adapters or cables are required, the coil is plug-and-play with the CTX 3030's multi-frequency platform.

The 11-inch DD coil's Double-D winding delivers strong target separation in trashy sites where coin spills and iron clutter overlap. The DD geometry reduces ground noise in mineralized soil and wet sand, maintaining stable threshold tones when single-frequency coils would chatter. CTX 3030 operators hunting colonial homesteads and urban parks use this coil to isolate deep silver and copper targets adjacent to modern trash. The coil's depth performance matches the CTX 3030's air-test capability, and the FBS 2 technology paired with the DD winding provides consistent target ID on deep coins buried among iron nails and aluminum scrap.

The 11-inch DD coil is designed for saltwater beach hunting and handles wet mineralized sand without signal drift. The coil's waterproof rating to 10 feet lets CTX 3030 operators work the surf line and wade chest-deep in saltwater, and the Double-D geometry reduces ground noise in high-mineral environments. We've run this coil in Gulf Coast surf and Pacific Northwest tide pools, and the CTX 3030's FBS 2 technology paired with the 11-inch DD delivers stable target ID on deep silver and modern clad. The included skidplate protects the coil face from shell beds and tidal rocks during low-tide hunts.

The 11-inch DD coil is the standard search coil supplied with the Minelab CTX 3030 metal detector. It ships with every new CTX 3030 and represents Minelab's baseline recommendation for general-purpose detecting in parks, beaches, and freshwater sites. CTX 3030 owners who wear out their stock coil or need a backup rely on this replacement to maintain the same depth, sensitivity, and target separation they expect from the detector.

The Minelab 11-inch DD coil is described as robust yet lightweight, reducing arm fatigue during multi-hour beach and freshwater sessions. Minelab does not publish a specific weight for the coil in the product documentation, but CTX 3030 operators report that the coil balances well on the detector's S-shaft and does not cause front-heavy swing fatigue during extended hunts. The coil's lightweight construction paired with the included skidplate delivers durability without adding unnecessary mass to the lower rod assembly.

The 11-inch DD coil is compatible only with the Minelab CTX 3030 and does not work with other Minelab detector models. The coil uses the CTX 3030's proprietary connector and multi-frequency platform, so it will not fit the Equinox, Manticore, or earlier Minelab FBS models without an adapter (and no adapter exists for cross-platform use). CTX 3030 owners looking to expand their coil arsenal should consider other coils - search coil build - open options designed specifically for the CTX 3030's FBS 2 technology.

Installing the 11-inch DD coil on the CTX 3030 requires the included hardware kit (mounting bolts and washers) and takes about five minutes. Align the coil's mounting holes with the lower rod's cam-lock bracket, insert the bolts through the bracket and coil ears, and tighten the hardware until the coil is secure but still adjustable for sweep angle. Plug the coil cable into the CTX 3030's control box connector, then wrap any excess cable around the lower rod and secure it with the included Velcro straps. The CTX 3030 will auto-detect the coil and load the appropriate settings, no manual calibration is required.
