Classic 2.0 Second Stage

The HOG Classic 2.0 second stage gives you ergonomic one-handed access to both the inhalation effort knob and the dive/predive venturi adjustment lever, making perfect regulator tuning easy. The most important feature of the HOG technical second stage is the amazing breathing performance! The metal gas tube and precision components of this second stage allow for precision tuning for extremely easy breathing while also retaining heat and moisture from exhaled breath. This provides increased resistance to freezing in cold water and less dry mouth. The dual diver-adjustable features allow for condition-specific tuning during each stage of the dive.
