About Farnsworth Banks
Farnsworth Banks is a deep offshore Catalina pinnacle with purple hydrocoral, vertical relief, and the kind of open-ocean diving that rewards disciplined gas planning. It is a boat-only site for experienced divers, and the best days combine calm seas, clear water, and a slow pass over the rock. Sea lions, barracuda, electric rays, and big black sea bass are the usual draw, with the hydrocoral fields making the site a California classic.

Scuba Diving
This is a deep boat dive that rewards conservative gas planning, line discipline, and a slow pass over the pinnacle and wall sections.
Freediving
Not a freedive target; the useful structure sits too deep and the open ocean makes it impractical.
