CB,
I noticed you are in Montco.
If you haven’t found a dive shop you could try Scubadelphia
in Northeast Philly. Their a friendly group and do pool training in PHiladelphia
and check outs either at Dutch Springs or the Jersey coast.
There is Northeast Scuba in Norristown, I’m not sure they are much into the training
any longer, but great for equipment, and they run a good six pack charter out of Breille.
