I dive with Scott's scuba in freeport. Great shop, They have a quarry called Crustys that is open in summer near grove city that we dive.
I also head to Crusty's a few times each year. It is a nice place to get in the water and see various boats, cars, random stuff and a plane. They have a mini-dive shop on site, air fills, gear rental, changing rooms, and a portapotty.
