Kelvin Lim –
I used the Seac P-SYNCHRO 230 BAR DIN Regulator on a recent cold water dive in Tioman and the airflow was steady throughout. It’s much lighter than my previous setup, and I definitely felt less jaw fatigue after two dives. The Venturi assist system really seems to help in current.

I’m new to DIN regulators and was worried about leaks, but the connection feels really secure. The construction seems solid and I noticed no free-flow issues even when changing depths. Great for my first upgrade from yoke.
