I got to Birch State Park about 8:30 am and took my time gearing up since the gate didn't open until 9:00 am. I headed down to the beach then and swam out to the swim buoy. Surf was rough, but manageable. Current along the shore was surprisingly strong. I could make head way against it, but it was a fight. Descended just past the swim buoy, but had to go NE before I spotted the old pin and then swam to the Big Rock. Off to a good start. I headed South with the current and found the smaller rock, but when I swam out at 130 degrees, I missed the knee high coral head. Didn't see the dead sea rod and never found the counter-weight. Think I might have gotten set to the South, or maybe I over corrected and went North, but I missed the knoll. Swam North to see if I could find anything familiar but I couldn't. Picked up some shells and golf balls and headed to the beach. Ran right to the swim buoy and killed some time getting down to 500 psi then surfaced and swam in.
Dive Time was only 100 minutes; consumption was 24.51 psi/minute at an average depth of 18 feet; SAC rate was 15.86 psi/minute; RMV was 0.41 ft3/minute.
