The correct answer is (c) The availability of regular, professional maintenance.
Almost all higher-quality regulators offer performance that is more than adequate for recreational diving right out of the box. To sustain that level of performance over the regulator's lifespan, you must be able to get frequent, professional maintenance.

What does a scuba diver's regulator do?</h3>
A regulator is a crucial piece of gear for scuba divers because it controls the pressured air from the tank and transforms it into breathable air. You cannot breathe directly from an air tank since they hold air under high pressure.
The scuba regulator is a fantastic technology that allows you to breathe with air directly from your dive tank. The center of your dive gear is a scuba diving regulator, which connects your scuba tank to your BCD, submersible pressure gauge (SPG), backup air source, and you.
