I would have to agree with Damieon. My son wanted to get certified at 12 (which he turned last May), but, I didn’t feel he was mature enough yet, so, I’m making him hold off. I have taken him down in 20feet of water at a local spring with me and he does quite well WITH me controlling the situation. I’m just not comfortable that he could keep his mind completely focused while he is in gear. So, yeah - I think you have to really base your decision on the ability and maturity of the child.
