Since ancient times, people have tried to dive under water. In 1943, modern scuba gear was invented. Today, using modern devices and materials, you can assemble scuba gear at home.
Instructions
Step 1
Download instructions from the Internet or follow the advice from specialized literature. Buy all the necessary components for making a scuba gear: a cylinder, a reducer, a lung governor, a hose, main and backup regulators, and a BCD.
Step 2
Prepare the balloon. Its volume can be either 7-18 liters or 20-22 liters, depending on your preferences. You can use 2 cylinders of 4, 7-7 liters each. Buy a 200 bar cylinder if you plan to do regular diving and buy a 300 bar cylinder if you do technical diving.
Step 3
Prepare the gearbox. The pressure for which the reducer is designed should be the same as in the cylinder, when choosing a reducer, be guided by the scope of application of the scuba gear. Connect the reducer and cylinder. Air should be supplied from the cylinder to the reducer, the reducer should reduce the pressure to medium (intermediate). Make sure that this pressure is 6-11 bar higher than the ambient pressure.
Step 4
Connect the hose to the reducer, attach the lung demand valve to the hose. If the lung demand valve is working properly and you have not made a mistake anywhere, the pressure should now match the ambient pressure. Connect the regulators. The number of regulators depends on the tasks you set for yourself while diving. If you are planning to go recreational diving, you will need 2 regulators: main and backup.
Step 5
Install a BCD. Although not required for the proper functioning of the scuba gear, it will make diving easier and safer. Pump up the oxygen cylinder and check the assembly you assembled. If all of its elements are connected correctly and the scuba diving is working, make the first test dive to a shallow depth. If it was successful, you can use scuba gear.
