Deep Blue is a small hole in the wall but is handy for that dive and he runs classes on the beach in Spanish BTW if you know anyone who wants to learn but English isn’t their best.
A local got me using a full service shop that was at A1A and East Oakland but I guess we didn’t use them enough, they’re gone :(
This is something of a drift dive, enter near the pier and get swept south a few blocks, then walk back, there are showers at each street end :)
