So i seen this first on the travel channel. i think this is awesome and Couples should look into getting these!!!!! Scuba diving is something i have always wanted to try, but the tank on my back and all the equipment makes me nervous and i'm afraid i might panic under water. Scuba doo sounds like a lot of fun!!!! and i think a lot of people would be interested in it. i wouldn't even mind being charged a fee. i don't think i did the link thing right, but you can just google scuba bike
