Tecline - TEC2 Second Stage — Black, EN250A

Tecline's upper second stage — pneumatically balanced, with breathing parameters Tecline state exceed the EN250A requirement rather than merely meeting it.

You get both adjustments: a venturi lever to switch the free-flow assist in and out, and a knob for breathing resistance. Open on a working dive, dialled down in current or when it is hanging as a backup.

The cold-water engineering is what separates it from the TEC1. Teflon coating on the metal parts and an integrated heat exchanger to move ambient heat into the gas as it expands — which is where a second stage freezes. The body is a temperature-resistant construction with a stainless steel outer ring (the TEC1 uses aluminium).

Airflow is handled by Tecline's Direct Flow System (DFS). 260 g, on an ergonomic mouthpiece.
