Hey Todd, welcome to the board! 5150 eeeh? Sometimes I think I need a 5250 due to my obsession with diving! LOL If you are free on Saturdays, Sundays, and Wednesdays, I might suggest you dive with the South Orange County Dive Club. You do not have to be a member to dive with the group. They meet up at the Laguna Hills Mall between Macy's and Kings Fish House @ 7:30am and they leave at 7:45am SHARP for Laguna.
I would love to dive with you at Corona Del Mar, but unfortunately I have to work with my 5150's and 5250's. It's pretty much a flat sandy bottom there, but you still see some neat marine life including an abundance of Sea Pansy's. If the surge isn't too bad, dive over near the jetty. Lots to see there as well.
Let us know how it goes.
Cheers,
