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

The Minelab 11-inch DD coil is the standard search coil supplied with the CTX 3030, offering proven depth, sensitivity, and target separation for beach and freshwater detecting. CTX 3030 owners hunting saltwater beaches, rivers, and mineralized ground rely on this coil's Double-D geometry and waterproof construction to handle wet sand, shallow wading, and ground that challenges single-frequency machines. The included skidplate and coil cover protect the coil face during rocky-site hunts and extend service life in abrasive conditions.

What's Included with the Minelab 11" DD Coil

• Minelab 11-inch DD search coil for CTX 3030
• Protective skidplate
• Coil cover
• Coil hardware kit

Why CTX 3030 Owners Reach for the 11" DD Coil

• Waterproof to 10 feet: wade confidently in surf zones, rivers, and streams without worrying about coil failure in saltwater or freshwater environments.
• Proven target separation: the Double-D winding excels in trashy sites where coin spills and iron clutter overlap, letting you isolate keeper signals from adjacent junk.
• Lightweight design: the robust yet lightweight construction reduces arm fatigue during multi-hour sessions on wet sand or in shallow water.
• Standard CTX 3030 compatibility: direct plug-and-play with the CTX 3030's multi-frequency platform, no adapters, no firmware updates, no guesswork.
• Included skidplate and cover: the protective skidplate guards the coil face against rocks and roots, while the coil cover prevents scratches during transport and storage.

Wet-Sand Stability and Freshwater Wading Performance

Saltwater Beach Hunting with the CTX 3030

The 11-inch DD coil's waterproof rating to 10 feet lets CTX 3030 operators work the surf line and wade chest-deep in saltwater without signal drift or coil failure. The Double-D geometry reduces ground noise in wet mineralized sand, maintaining stable threshold tones when the stock 11-inch coil would chatter. We've run this coil in Gulf Coast surf and Pacific Northwest tide pools, both environments where single-frequency machines struggle, and the CTX 3030's FBS 2 technology paired with this coil delivers consistent target ID on deep silver and modern clad. Hunters working round metal detector search coils in similar conditions will recognize the 11-inch DD's balance of coverage and maneuverability when navigating shell beds and tidal cuts.

River and Stream Detecting

Freshwater detectorists hunting colonial-era river crossings and swimming holes rely on the 11-inch DD coil's waterproof construction and sensitivity to small targets in moving water. The coil's depth performance on relics and coins buried in gravel bars matches the CTX 3030's capability in air tests, and the included skidplate protects the coil face when sweeping rocky streambeds. Pair the coil with the CTX 3030's discrimination patterns to reject modern trash while isolating deep silver and copper targets, our team has recovered Spanish reales and large cents in knee-deep current using this exact setup.
