All three FMF coils share the same simultaneous frequency capabilities, but their physical size creates distinct tactical separation benefits in the field. The compact 9-inch round coil delivers surgical target separation in heavy iron clutter and lowers ambient ground feedback in mineralized soils, making it excellent for gold prospecting or trashy urban yards. The mid-size 11-inch version balances depth and coverage for general multi-purpose scanning. The oversized 13x11-inch elliptical model focuses purely on deep target penetration across wide open pastures or clean sand lines. All FMF configurations are interchangeable, allowing you to add accessory sizes as your hunting terrains expand.
