Low Pressure Bell

[rzk4sb]

Does anyone know which regulators feature the bell-ring each time you breathe <1000 psi? It's not a crucial thing to me, I'm more interested in knowing if this is becoming a norm in the technology these days.

Thanks

The Scuba Pro Mk VII (no longer in production and aka Honker) has an aural warning when supply pressure gets low. But if I am not mistaken, the bell you're thinking of was actually a tank valve with a hammer pin that would hit the interal walls of a tank.

I think Healthways made a reg called the Sonic, but I don't know anything about them.

I think Scott packs (SCBA) have a bell to signal low supply pressure, but they are not for diving.

Cool, thanks. Just as an FYI, my brother recently got a new reg which had this feature. I'll have to ask him the brand.

The Mk VII honked, but I am not aware of any regs that rang bells.

However there was at least one tank valve that had a clapper in it. Everytime you inhaled after the pressure dropped below 500 psi it banged against the inside of the tank making a bell sound.

You are possibly referring to the DVT regulators which have a stopper in the inlet. These things are becoming more widespread in the market and may produce strange noises.

It's the Oceanic Delta 4.

Why would you want to hear a bell ring for each breath below 1000 psi?

This is probably a gimmick rather than a potential accepted 'norm'.

Sorry but I don't know of the regulator you are looking for. :blinking:
