Yes, the INV28 coil handles saltwater surf zones effectively due to its fully waterproof construction and DD coil geometry that cancels saltwater ground noise. The Double-D field pattern rejects the mineralization signal from wet saltwater sand, allowing stable tone response across the wet-to-dry sand transition line where concentric coils often false. The waterproof design allows you to sweep from dry sand into shallow water without performance degradation. Rinse the coil and cable with fresh water after each saltwater hunt to prevent salt buildup on the connector and maintain long-term reliability.
