There aren't many places in the Phoenix-metro area that can boast being in business for 45+ years. I've been to many a scuba shop and its always nice to see a family owned and operated business thrive amongst the big box sports stores. If you are thinking about getting certified think about this: Do you want to be in a corporate setting with an instructor who has never been in the ocean OR do you want to be around incredibly knowledgeable/experienced staff in a really cool yet safe and professional setting? Oh....and they beat anyone's price on certifications and equipment; apple for apple.
