One thing that I feel strongly about is.. You can buy alot on line and save . Your regs and BCD should be bought threw your local shop. They are factory trained to properly maintain them and as for warranty and regular service, that as well is usually less expensive and fast turn around time if you bought it from them. I am not against buying items on line by no means. REMEMBER ONE THING>>>> buying from and suporting your local shop means it will be around when you need it...Makes sense dosent it.... good luck in you course. Enjoy the sport as much as alot of others do... Stay safe
