Reliable weather forecasts are essential when navigating.

Therefore VION's R&D Department developed a "special marine" electronic barometer specially designed for navigation and which has many elaborated functions to assist decision-making.

Barometer : detects even the smallest pressure variation - professional accuracy +/- 0.5 hPa
Night navigation : basic light incorporated
Low consumption : requires 2 LR03 batteries, average battery life= 1 year.

- Graph indicating the pressure changes over the previous 24 hours

- Zoom : a focused view of the air pressure changes over the previous 6 or 12 hours.

"Detect a reversal of the pressure trend". HIST FUNCTION: immediate recall and visualization on the graph of the minimum and maximum pressure over the last 24 hours.

"See the evolution of the pressure trend (change of watch)": MEM FUNCTION: with immediate display of a situation stored and visualization on the graph.

"Foresee the arrival of low pressure or of an approaching anticyclonic wedge": ALARM FUNCTION: with adjustable sensitivity.

Gale warning system: pressure drop = 4hPa within a 3-hour period.

Continuous safety: running reserve allowing batteries to be changed without loss of information.
