Boogie711:OK - hold up - Joel, I respect you, I've defended you and your company many times in the past when you used to post on TDS... but why on earth would you let a 6 year old breath compressed gas? Isn't that just asking for an embolism or other over expansion injury?
first and foremost both I and my wife are pretty accomplished scuba divers and instructors. 2nd our daughter is a highly accomplished swimmer and has been around scuba since she was crawling over our gear as an infant. She can probably recite boyles law and its effects better than most. 3rd. she only uses it under direct and constant supervision of one of us. Would I let her use it alone ? Hell no.
She's actually pretty good at it. Would we expect anything else?

JDS
