    The CORS Giant 15x17 DD coil transforms your Minelab X-Terra into a deep-seeking powerhouse that outperforms stock coils by 30-60% in detection depth. This massive waterproof coil excels at finding large relics and coins that smaller coils miss entirely.

    Key Performance Benefits

    • Extreme depth capability - 30-60% deeper than stock X-Terra coils

    • Massive ground coverage - 50-80% more area per sweep saves hunting time

    • Versatile target detection - finds large relics and small targets (1g+) at 25cm depth

    • Fully waterproof design - submersible with epoxy-filled construction

    • Universal X-Terra compatibility - works with all frequencies (3kHz, 7.5kHz, 18.75kHz)

    • Professional durability - 2-year warranty with German-made cable

    Built for Open Terrain Hunting

    The Giant coil shines in parks, fields, and beaches where you can take full advantage of its size. At 15x17 inches, it's designed for serious detectorists who want maximum depth on large targets like caches, relics, and deep coins. The Double-D configuration maintains good target separation even at this size.

    This coil works with all Minelab X-Terra models - the 305, 505, and 705 - across all operating frequencies. The screw-on connector and robust mounting bracket handle the coil's 32.4 oz weight without stress on your detector shaft.

    Professional Construction Details

    CORS fills each coil with high-quality epoxy resin for complete waterproofing and durability. The outer shell uses UV-protected, impact-resistant plastic that stands up to rocky ground and beach use. Gold-plated contacts ensure reliable connection, while the larger cross-section cable reduces signal loss.

    Complete Package Includes

    • 15x17 inch DD search coil with attached skidplate

    • Protective coil cover

    • Mounting hardware (nut, bolt, rubber rings)

    • Velcro cable strap

    • Full 2-year manufacturer warranty

    For hunters serious about finding deep targets that others miss, the CORS Giant delivers professional-level performance. Check out our complete selection of waterproof coils to find the perfect match for your hunting style.
