The INV56 is fully waterproof and submersible, making it suitable for surf zone detecting, shallow river hunts, and wet-sand beach work. The DD coil configuration provides effective ground balancing in saltwater environments where high mineralization can destabilize other coil types. You can run this coil in the surf and across tidal flats without risking water damage. For saltwater beach detecting, pair the INV56 with your Invenio's beach mode to handle the conductivity of wet sand and seawater while maintaining stable target signals on coins, jewelry, and relics buried in storm cuts.
