Hello
My son and I have taken an interest in rebreathers and purchased a Dolphin to learn on. We always attempt to get as much info as possible before actually using any new products added to our dive gear. Our dive shop has multiple rebreather divers, and this site seems to have a wealth of info. We will be scheduling our classes and in the mean time keep gathering additional materials. We live in Pittsburgh, PA and dive in multiple locations both fresh and saltwater. I am a MSDT and my son is a Master Diver. I look forward to tapping into the knowledge here. Safe Diving.
