How to clean the Minelab CTX 3030?
Hose the detector with clean water after use on the beach (wading or submersion).
If, through extensive use, the carbon-fiber upper or lower shafts become noticeably scored,
wipe these thoroughly with a damp cloth.
Do not use solvents to clean the detector. Use a damp cloth with mild soap detergent. Wash
connectors with distilled water.
