hey there i havent been scubadiving for too long but im really intereseted in rebreathers so that i can enhance my scuba diving experience, but i have absolutely no knowledge of the different kinds. I understand that they filter ur breath in to an area with an oxygen tank and make it rebreathable, but are theyre different types. I have heard of something called a dragger rebreather but i dont know if that is any different than a regular one. I also would like to know what they mean by closed and open circuit rebreathers. Im assuming that the open circuit ones probably let out some bubbles, but then why not just use a tank if this is the case? thanks very much!
