I sat on the beach and watched everyone 's stuff and tried to refresh my memory with Nodettelet(1 ) 's open water book . It turned out to be much more amusing to watch the other dive groups that showed up . Some of the main rules in diving are try not to put your gear in the sand ( bring a tarp ) and lay your tanks down unless you are holding it or wearing it . Tanks can fall over especially with your gear on and they can turn into missles ( see Mythbusters ) .
