Detailed Answer
Shipyard salt-spray protection: 1. Salt-resistant housing material; 2. Conformal coating on PCBs; 3. Sealed gold-plated connectors; 4. Weekly fresh-water rinse; 5. Storage in dry cabinets. The LDER LD series shipyard edition passes salt-spray testing (GB/T 2423.17); XINGJIA likewise. Dock salt-spray concentration is high, so both protection rating and maintenance matter.
