Con grads to you and your son. He may be cute now, but pretty soon he will be a teen and not so cute and easy to get along with. Having diving in common will be an activity that binds u and let's you spend time with. I know of what I speak as my son began diving with me at 14 and now that he's 16 it is a precious precious thing to us that we spend time diving together. I tell people that getting wet diving is not my favorite aspect of diving, it's the shared adventure and time spent with family and friends.
Deercreekers Jr and have learned to shore dive and lobster together. I wouldn't trade these times, the talks, the shared laughs (and misery) together for the world.
FYI, we are in the Valencia area and have moved from bcds and standard set ups to bpw and 7 ft hoses, we have our old equipment, including a bcd that might fit ur boy. Need to get rid of it (hubby says it takes up too much space and is just sitting there). Ur welcome to root thru it and see what u can make work for u for probably an astoundingly good price (like come get it and give me a couple hundred bucks for it and it's urs). 3 bcds, 2 sets of regs and whatever else were not using.
FYI-do not buy a wetsuit new for ur kid, Jr went thru several on his way to his 6'1 height now. Although we did buy two used Jr wet suits on scuba board that were a fantastic price so that I didn't mind he only got 6 months use out of each.
That said, owning ur own equipment, even if it's only a bcd and regs, adds gobs of confidence for youngsters.
Good luck, drop us a line if ur interested in rooting thru our equipment or if u two would like to joins Mark and I for a shore dive or two when ur comfortable diving that sort of diving.
