Max Repair is a waterproof adhesive sealant that reseals the XP coil housing after you open it to replace the battery. XP coils are sealed units to maintain their waterproof rating, and breaking that seal to access the battery compartment exposes the internal electronics to moisture risk. The Max Repair sealant creates a waterproof bond between the housing halves, allowing you to continue hunting wet sand, shallow water, and rain without water intrusion. The sealant is essential for maintaining the coil's original waterproof integrity after the repair. For more on how wireless coils function, see our guide to metal detector technologies.
