Over the years, Scubapro have continuously developed their piston 1^st stages. This week they announced their new MK21, a compact, balanced 1^st stage with a high rate of air flow which they say guarantees smooth and undisturbed breathing, even when diving deep and with low cylinder pressure.

Here are more details on the product taken from the official press release:

The external fins optimise the heat exchange providing the MK21 with an excellent cold water resistance. The MK21 is 16mm smaller as the MK25, but the performance is by no means reduced. Through the intelligent hose layout this impressive 1^st stage allows easy identification and perfect positioning.

Thanks to the optional head the MK21 is the ideal 1^st stage for technical diving. The regular head can be replaced with a 5 LP-port head for the optimal technical diving hose configuration.

The Concept

• Compact size (only 76mm)
• Brand new medium piston 1^st stage
• Replaceable head for unique hose configuration
• AF System for best cold water performance
• LP and HP hoses smart layout
• Easy maintenance
• Perfect symbiosis between performance and sensitivity
• 2 HP Ports / 4 LP Ports (optional head with additional high flow LP TOP port)

The Design

• Unique design
• Streamline shape
• Polished chrome finishing
• New cap matching the style
• Very compact forged body (only 46mm diameter)
• External fins for optimal thermal exchange and anti-freezing resistance
• Re-designed yoke and cap

Functional Highlights

• Optional replaceable head for optimal positioning with 4 LP routing configurations (0°/30°) – ideal for technical diving
• Standard head with 4 LP hose routing (+/- 20°)

MK21 in Combination with G260

The G260 is a balanced, adjustable 2^nd stage featuring metal components for excellent cold water resistance (inlet tube, orifice, inhalation control knob, and hose connector). Its high performance makes it a choice for all demanding divers and it will be the natural choice for G250 fans. The left-right hose attachment option makes it ideally suited for tech diving configurations.

Details

• Metal barrel
• Left-right hose attachment, ideal for technical configurations
• Metal front ring with coarse thread that can be easily screwed on or off
• Larger mouthpiece for a natural breathing comfort
• Streamlined lever
• Large diaphragm for an incredibly low breathing resistance

The new MK21/G260 is now available from all authorised Scubapro dealers.
