Extra breathing tube can lengthen time under water
Langdon Stimson developed a new type of snorkel called an extra breathing tube that, as its name implies, allows you to breathe in water. It will allow you to spend twice as much time than using a standard ventilation tube. Underwater. Have you ever snorkeled, dive free, explore coral reefs, hunt fish, find shells in the ocean or any other underwater activity, do you wish to stay diving, but you have no money, time, observers, etc? This simple, J-shaped breathing tube can be improved.
The extra breathing tube, a very simple and easy-to-use device, doubles your time and fun, and when you are underwater, you believe that the final product will be more compact and ergonomic than the current prototype.
