Scubapro 將旗下最暢銷的二級頭與性能最強勁的一級頭結合，打造出潛水員夢寐以求的完美組合。MK25 EVO 一級頭：具有卓越的防凍性能、出色的吸氣靈敏度，並能即時提供所需氣流，確保潛水員在任何情況下都能輕鬆呼吸。S600 二級頭：採用堅固的玻璃纖維外殼與不鏽鋼前蓋及環圈，無論深度如何，都能提供穩定且順暢的氣流。無論水溫高低，或面對最嚴苛的潛水環境，這套調節器系統都能表現出色，為潛水員提供無與倫比的呼吸體驗。

一級頭 (First Stage)

• 採用鍍鉻黃銅機身的氣體平衡貫通活塞設計，確保氣流穩定且順暢，不受深度、氣瓶壓力或呼吸速率的影響，讓潛水員在任何情況下都能輕鬆呼吸。
• 專利 XTIS（延伸隔熱系統）：全面隔絕內部機構與外部環境的熱傳導，提升 30% 的冷水適應性，並在極寒水溫下延緩結冰現象，同時不影響呼吸性能。隔熱系統的關鍵部件以藍色標示，便於識別。
• 升級隔熱設計：新型彈簧隔熱塗層、機身隔熱襯套、防凍蓋，以及加大的機身與蓋螺紋，均與 XTIS 協同作用，進一步提升冷水環境下的能表現。
• 防凍保護：大幅提高在極端水溫下潛水時的呼吸可靠性。
• 雙向高壓接口：兩個相對的高壓接口設計，讓一級頭可根據需求選擇向上或向下安裝。
• 五個高流量低壓接口：搭配旋轉式轉盤，提供最大的管線配置靈活性。
• 外部中壓調節功能：讓技術人員能夠快速且輕鬆地微調性能。
• 重量（INT 232 規格）：790 克。
• 氣流表現（200bar）：>8500 升/分鐘。
• 中壓範圍：9.0-9.8 bar。

二級頭 (Second Stage)

• 氣體平衡閥設計：在不同深度與供氣壓力下，確保吸氣阻力平穩順暢，讓潛水更加輕鬆。
• 金屬閥體結構：堅固耐用，能夠承受多年高強度潛水使用。
• 用戶控制功能：包括可調節吸氣阻力的旋鈕，以及 Venturi 真空輔助（VIVA）潛水/預潛水開關，操作直覺便利。
• 超大內徑呼吸管：超流量設計，確保每次吸氣都能提供充足的氣流。
• 符合人體工學的矯正型咬嘴：佩戴舒適且不影響氣流暢通，適合長時間使用。
• 重量（不含咬嘴）：200 克。
• 氣流表現（200bar）：1850 升/分鐘。
• 最大低壓輸出：14bar。
• 可更換排水閥蓋：提供個性化選擇，讓你的調節器獨一無二。

Combining SCUBAPRO’s best-selling second stage and its top-performing first stage is a match made in diver heaven. The MK25 EVO offers excellent resistance to freezing, superb inhalation sensitivity and instant delivery of air on demand. The S600, with its rugged fiberglass casing and stainless steel front face and ring, provides a steady, effortless flow of air, regardless of depth. In all water temperatures, in the most demanding dive conditions, this reg system performs flawlessly.

First Stage

• Air balanced flow-through piston in a chrome-plated brass body provides constant and effortless airflow unaffected by depth, tank pressure, or breathing rate.
• Patent pending XTIS (Extended thermal Insulating system) fully insulates the inner mechanism from the environment, improving cold-water resistance by 30% and delaying ice formation in extreme cold-water conditions without compromising breathing performance. Key insulation system components are visible in blue.
• New spring insulating coating, body insulating bushing, anti-freeze cap, bigger body and cap thread all work in concert with the XTIS to improve cold-water performance.
• Anti-freeze protection radically increases breathing reliability when diving in the most extreme water temperatures.
• Two opposing high pressure ports allow the first stage to be positioned either up or down.
• Five high-flow low pressure ports on a swivel turret maximize hose routing options.
• External intermediate pressure adjustment enables technicians to fine-tune performance quickly and easily.
• Weight: INT 232: 790g.
• Airflow at 200bar: (l/min): >8500.
• Intermediate pressure (bar): 9.0-9.8.

Second Stage

• Air-balanced valve smoothes out the inhalation effort when diving at varying depths and supply pressures.
• Metal valve housing is able to withstand years of aggressive diving.
• User controls include a diver-adjustable inhalation effort knob and Venturi-Initiated Vacuum Assist (VIVA) dive/ pre-dive switch.
• Super-flow hose features an oversized bore that allows more air to flow on each inhalation.
• Ultra-comfortable orthodontic mouthpiece is easy to grip yet doesn’t inhibit airflow.
• Weight (without mouthpiece): 200g.
• Airflow at 200bar: 1850 l/min.
• Maximum low pressure: 14bar.
• Changeable purge covers allow you to make your regulator truly unique.
