He’s actually very familiar with and has a good understanding of dive physiology just from listening to me for the past three years, LOL! I’m interested to know if anyone can recommend manufacturers of equipment in youth sizes. Obviously I’m not going to buy anything until he’s ready, and he’s been growing so quickly, if I were to buy anything now he’d most likely outgrow it by the time he was ready to use it. Does anyone have experience with diving with their children that could maybe pass along some advice? Thanks, Joe
