My ten year old daughter is a PADI certified scuba diver. She did her classroom and pool lessons with Mr. Sherman Casto at Stingray Scuba. Mr Casto is a highly skilled instructor who made my wife and me very comfortable as we trusted him to teach our precious daughter. He was extremely knowledgable and is able to teach basic scuba diving with great patience. He is also able to teach advanced skills with great expertise. He has a shop and equipment to fill tanks and service regulators. My daughter did her checkout dives in Florida and her dive instructor in Florida was very impressed with her skills; thank you Mr. Casto for teaching her well.
