B-AXIAL Search coil - DETECT AT THE NEXT LEVEL
Part of the ”Secret of Success” is the revolutionary NEW BIAXIAL™ search coil. Here is a totally new search coil that penetrates all soils deeper than ever before. Soils that resisted other detectors and other search coils, such as high ironmineral soils, conductive soils and saltwater beaches are now able to be penetrated to give up all their hidden treasures that have yet to be found. This dynamic innovative 11inch Open Frame Biaxial Search coil is super sensitive and detects coins to 15 Inches, and as a BONUS the screen identifies your target (coin, ring etc.) and Tone I.D. also identifies your target. You know what’s under the coil BEFORE you dig!
