Blackwater SAC in Fermoy are running a series of lectures on Friday evenings in January to March 2014. You can download the flyer for details: 2014 Blackwater SAC Evening Lectures. There’s a very small cover charge, but the Blackwater guys have a long history of giving entertaining and informative talks; well recommended.
The Blackwater clubhouse is on the north side of Fermoy: here it is on Google Maps. If you’re interested, contact the Blackwater club Dive Officer, Graham Burke (his phone number is on the flyer).
