Actually the one from NASA (UK company not the space agency...)
has a nice screen that shows you the pressure as number together with a graph with the speed of rise/fall of the air pressure set in time. Much more useful then the screen in the picture

I have the same unit, purchased about 10 years ago through Weems & Plath in the U.S. W&P dropped the unit shortly thereafter, and the instructions I had referenced a German company as the OEM. I was not able to locate that company and assumed it had gone out of business. That was a shame as my unit promised a USB interface for NMEA output with a later release of the firmware. Now, thanks to Monte, I discover it is really made by a French company and still is in business. I should have guessed that as the default language on initial power up is French.

This has been a very useful device, even though I've had to adjust the pressure tendency warnings to avoid them going off for normal diurnal pressure changes. Also changing batteries is a PITA, but it works fine off 12VDC.

I'm trying to find the VION company on the net, but all I get are the resellers, which don't provide a lot of info on the current product. I'd like to find out if they ever implemented the USB NMEA interface and if a firmware upgrade is available for my old instrument.

Anyone have a contact point for VION. On the net perferably so I could communicate in English, as my French is pretty disfunctional.

I have a Maretron wind & weather sensor that does barometric pressure. It is then up to a display to draw a graph and my Maretron display does a great job while the Furuno does not.

If use the barometer with other device from this company - Voyage recorder, values are written to the sd-card. And use the free software you can generate and print the logboook for you vessel with all the values from the NMEA 2000 network, including pressure

Barometer from Yacht Devices is cheaper. It coast only 99 USD.
