The Tecline R2 TEC2 rev. Side Mount Extreme Set is a regulator package designed for divers who require uncompromising reliability, streamlined performance, and adaptability in demanding sidemount environments. Built around the R2 first stages and TEC2 second stages, this set is engineered to meet the needs of both recreational and technical divers exploring caves, wrecks, or extended penetration dives. Certified to the EN250A standard, it ensures dependable operation even in cold-water conditions, making it a trusted choice for extreme diving scenarios.

This regulator set includes all the essential elements for a robust sidemount configuration:

• 2 × R2 First Stage Regulators with 5th Port – Balanced diaphragm design with dry chamber technology, engineered to prevent freezing and deliver consistent airflow in cold or silty conditions. The 5th port provides enhanced hose routing flexibility, ideal for sidemount setups.
• 2 × TEC2 Second Stage Regulators (Reversible Version) – High-performance demand valves delivering effortless, natural breathing at all depths. The reversible design allows hose routing from either side, offering maximum adaptability for sidemount divers.
• 2 × Swivel 90 Degrees – Improves hose positioning and comfort, reducing strain and enhancing streamlining.
• 2 × LP Hoses (65–70 cm) – Optimised length for sidemount regulator placement, ensuring efficient and comfortable hose routing.
• 2 × INFL LP Hoses (20 cm) – Compact inflator hoses for buoyancy control devices, designed for minimal drag and easy handling.
• 2 × HP Rubber Hoses (20 cm) – Durable high-pressure hoses for connecting SPGs, ensuring reliability and precision.
• 2 × SPG 52 mm, 300 bar – Submersible pressure gauges providing accurate tank pressure readings, critical for monitoring gas supply.
• 1 × SS Bolt Snap 88 mm – Stainless steel bolt snap for secure attachment of gauges or accessories.
• 1 m Bungee, Diameter 4 mm – Used to secure backup regulators, ensuring immediate access and streamlined stowage.

The R2 first stages are crafted from maritime brass with a frosted chrome finish, ensuring durability and corrosion resistance. Their balanced diaphragm system maintains stable intermediate pressure, while the dry chamber design prevents ice formation, making them exceptionally reliable for cold-water and sidemount diving. The addition of the 5th port allows for optimal hose routing, reducing clutter and improving diver comfort.

The TEC2 reversible second stages complement this with extraordinary breathing performance that exceeds EN250A requirements. Divers benefit from smooth, low-resistance inhalation, even under high workload or at depth. The reversible design provides flexibility for hose routing, making them perfectly suited to sidemount configurations.

Swivels, compact hoses, and SPGs ensure streamlined movement, reduced drag, and precise monitoring. The inclusion of bolt snaps and bungee accessories allows divers to secure and stow regulators efficiently, maintaining a clean and organised sidemount profile.

Certified to EN250A standards, this regulator set meets stringent European safety requirements for cold-water diving. It is trusted by technical divers worldwide for its ability to deliver consistent breathing comfort and safety in demanding environments.
