Expert Field Care and Maintenance Tips 

To maximize the lifespan of your underwater power pod, always inspect the connecting seals before entering the water. Ensure that the sealing surfaces are clear of fine beach sand, salt crystals, or grit that could break the vacuum seal under pressure. After spending the day detecting in saltwater environments, thoroughly rinse the exterior of the battery pod with clean, fresh water to prevent salt crystallization around the contact points. When storing the NiMH pack during the off-season, charge it periodically to prevent the cells from dropping into a deep discharge state, which preserves overall battery health.
