user manual

The R4 TEC first stage scuba regulator is a high performing balanced diaphragm regulator with dry chamber / cold kit in a compact format. This popular design includes 4 x LP ports, allowing for a dry suit hose in addition to regulator and BCD hoses. There are also 2 x HP ports, which allows flexibility to mount the regulator in either a standard or inverted position.

The TEC2 second stage regulator is pneumatically balanced and features Tecline's direct flow system, with an innovative, compact design for better breathing performance. The TEC2 has Venturi effect flow adjustment and breathing resistance adjustment, and feature a stainless steel guard and reduced purge area for excellent performance in extreme conditions.

The TEC2 OCTO has the same high specifications as the primary TEC2, including Venturi and breathing resistance adjustment, but it has a yellow purge cover.

A bit about regulators

Breathing resistance and work of breath are determined by regulator design and maintenance. Optimal performance requires maintenance by a skilled technician with the appropriate tools.

A good regulator tuned correctly will almost free-flow into your mouth as you inhale. That's the Venturi effect working for you to minimise effort. So it's good practice to switch an unused Occy or second regulator to the minus or pre-dive mode to spoil the Venturi effect and prevent free flows.

In some cases, a new regulator may be tuned for diving in extreme cold. This increases breathing resistance to prevent free flows that may result in ice forming. In this case, the breathing resistance knob can be wound out (turn anti-clockwise) to reduce breathing resistance and make breathing easier.

The breathing resistance knob on a second stage stops minor leaks by increasing the pressure of the sealing seat onto the orifice. This is intended for expeditions / holidays to stop a minor leak until the regulator can be serviced.
