Did Mainland tunnel at Ginnie today. The main Tunnel heading there is much cloudier than Normal but clears somewhat at about 2700'.
Mainland clear until about 3500' where it gets shallower. Then it's lights out. Very dark brown tannic water with 10 to 15' vis. Went to the T at 3800' and went right in the tunnel leading to Sweet Surprise. This tunnel clears a bit.
Still a fun dive though.
