Keep me posted .I am retired so I am free . The depth is 22 Ft. so 1 tank will last 1 1/2 to 2 hr.’s dive time . Foster park fills up fast some times when it’s packed the park shuts down . The thing I do is get there 1 hour before dive time . Dive time will start 1 hour before high slack tide so that means 2 hr. before
" HIGH TIDE ".
