Good deal for scuba divers at Balt. boat show
 

Any certified scuba divers going to the Baltimore boat show on Fri or Sat. can get into the dive show at 50% off. Dive show is next to boat show - I think in same building.

All you need to do is show a valid C card to get the discount. Sounds like a decent dive show - lots of new equipment is featured.

If you buy a Judge - you get free dive tank holder :D
