How is the DVL protected against corrosion and erosion?

We typically hard anodize and then paint our standard DVLs. Sacrificial anodes are fitted to the DVL to prevent corrosion (See Workhorse Navigator manual for correct installation procedure of the anodes for the DVL). As for water ingress, our units are sealed with O-rings for operation at pressure. A desiccant bag is put inside the unit to remove any internal residual moisture or humidity.
