A tankless dive system, also known as a rebreather, is a scuba diving apparatus that recycles exhaled breathing gas, removing carbon dioxide and adding oxygen. This allows divers to stay underwater for longer periods of time without having to surface for air.
Tankless dive systems offer a number of advantages over traditional scuba gear. They are more lightweight and compact, making them easier to transport and use. They also produce less noise, making them ideal for stealth diving or underwater photography. Additionally, tankless dive systems can be more cost-effective in the long run, as they eliminate the need to purchase and fill scuba tanks.
