US Patent 10079010 Compact solar mount

A mounting, positioning, and deployment system for the sonar head of a sonar survey system facilitates rapid, accurate, and repeatable alignment of the sonar head in relation to the keel of a marine vessel. Precision and stability are enhanced with refinements to a cross tube positioning apparatus, and further enhanced with an adjustable Z-pole mount and an extruded aluminum Z-pole embodied as, or encased in, a drag-reducing foil.
