Nothing seems more challenging than choosing the perfect regulator out of the multitude of options. But you simply need to ask yourself a few questions. Where do I want to use the regulator: In warm or cold waters? Do I want a high-end model or a more simple solution? Do I need a DIN or a yoke system?
Once you answered these questions, you will have a better idea of what to look for in a regulator. You can choose between more basic regulators or regulators with more advanced functions, you can choose regs that are balanced for effortless breathing at all depths, regs that have adjustable breathing resistance, or regs that have environmental seals to keep them from freezing up in cold waters.
If you primarily dive in cold waters, the Scubapro MK17 / A700 combination has an environmental sealing system to keep water from entering the first stage to stop it from freezing up. For warmer waters, Scubapro's all-time best-selling MK25 / S600 combination has a very smooth airflow for effortless breathing. Or for a minimalist approach, you can change your BCD inflator to a regulator that delivers superior performance in a compact and lightweight design with the Scubapro AIR2.
