We did our Open Water Certification through the Scuba Tank. The instructors were awesome and they worked to accomodate our strange hours (we work midnights). We felt that the instruction given to us was top notch. However, the equipment that they sell is high priced. You can find much better prices on equipment on line at Scuba Toys. Don't let the staff at Scuba Tank tell you that you won't get a manufacturer's warranty if you buy on line. You can still get a manufacturer's warranty from Scuba Toys (it's www followed by a dot followed by scubatoys followed by another dot and then followed by com). I'm all for supporting my local dealer (Scuba Tank) but they need to be able to compete better with on line pricing. I give Scuba Tank 4 stars. I would give them 5 stars if they had better prices on their equipment.
