Mixed gas rebreathers
A career as a mixed-gas rebreather diver is something you might be interested in. First, you should know that you need to complete certain prerequisites in order to become certified in this type of diving. You should have at least one year of experience with a rebreather as well as experience diving to certain depths.
A mixed gas rebreather can pose some risks to your safety. A failure of the gas injector system is one of the most common. This problem is more common with mixed gas rebreathers than in oxygen rebreathers. These systems can be manually bypassed in the unlikely event of a malfunction.

Regular maintenance will extend the life of the unit, reduce the likelihood of the unit failing to dive and increase its efficiency. For proper maintenance and care, be sure to follow the instructions in your rebreather’s manual.
Rebreathers are temperamental pieces of equipment, so you must learn how to maintain them properly. You should also perform pre- and post-dive inspections. Additionally, it is essential to know how to use the equipment correctly.
