■ Regulator Considerations Anyone involved in product development at an industrial manufacturer would understand that even the most excellent industrial products are still in development when they are newly released. Since diving equipment regulators are industrial products that can be used continuously for over 10 years, at the very least, the basic structure should be from models with over 10 years of sales history, otherwise, there may be recalls. While the reliability of well-established models from top manufacturers is high, even if you regularly overhaul the equipment to restore it to its original condition, it is physically impossible to maintain it in the same state as when you purchased the equipment, and it is undeniable that it will appear as old and worn-out equipment due to aging. ■ What is Restomod? In recent years, the term "restomod" has become a global trend, combining "restore" and "modify." The main modification in restomod involves replacing deteriorated exterior materials, which have been heavily used in actual environments, with different materials such as carbon fiber. The definition of restomod is to revive and brush up classic masterpieces with modern technology by adopting lightweight and high-rigidity parts. ■ About SCUBA PRO / MK20 The first stage MK20 is praised as a masterpiece representing SCUBA PRO. The company has consistently adhered to the balanced piston type for its 1st stage, steadily evolving from MK2 → MK10 → MK20, and it can be said to be the best of the balanced piston type regulators. ■ Restomod Details A special process of vapor-depositing a carbon graphite sheet on the face cover of the G250 has been applied. Unlike the cheap work of simply applying a sticker, the carbon graphite sheet vapor-deposited with excellent techniques will not peel off semi-permanently, even in the harshest environments for industrial products, such as seawater and deep-sea diving.
