Helo 66 recovery?

I stumbled across a website that mentioned the helicopter used in many of
the Apollo spacecraft recoveries which had the big "66" painted on its side.
The site said that this Sea King was lost in 1975 off the coast of San Diego
when it got pulled into the water while using its dipping sonar.

The site was unclear, but did the sonar actually catch on a submarine?

Also, the site said that although the US Navy incident report claims that
the helicopter is in very deep water, divers have actually located the wreck
in only about 230 feet of water and there is a group seeking to recover the
aircraft.

Anybody know any details?
