Wow, very nice. Set the Sand Dollar as my background. What hardware are you using, and where are these grass areas in PC?
Thanks for your comments!
My camera is a Canon PowerShot A630 in a Canon housing. It's three years old, and was a middle-of-road point & shoot when I bought it. I've been quite happy with it, although I suppose it's time to consider an upgrade. Only problem is an upgrade means a bigger camera and bigger housing, which may not be a convenient size for the off-the-beach snorkeling that I typically do.
The grass flats appear to occupy a continuous band along the north shore (bay side) of Shell Island. They peter out at depth of about 8 ft where the bottom of the bay slopes into deeper water. We anchored for most of the day off Spanish Shanty Pt., which is marked on NOAA charts, although I don't know if there is anything particularly special about this spot. Spanish Shanty Pt. is maybe 2 miles east of the Pass. I also rented a pontoon boat in PCB last year, and initially went much farther east based on the recommendation of the rental company. The water there turned out to have a murky 6 ft of visibility, which is unacceptable to me. We ended up moving to near Spanish Shanty Pt. and the vis. was much better, so that is where I went this year. In retrospect, it only makes sense that the closer you are to the pass, the better the visibility will be. Most of the time I was snorkeling in about 4 ft. of water.
