Reliable weather forecasts are essential when sailing.
Therefore, VION has decided to equip all barometers (except for the references 100 SAT B and 100 LD B) with this new technology, undoubtedly a new standard, developed by VION's R & D engineers.

It offers you :
             • Sensitivity: the slightest pressure change is
                detected by the barometer
             • Amplified reading :the movement of the hand
                 is amplified 1.5 or 2.2 times more than on a
                 traditional barometer
             • Linearity: the barometer is "truer"
             • Control certificate with the "double capsule" models.

There are two versions :

• " Hi-Sensitiv " simple capsule mechanism : movement of the hand amplified 1.5 times
          Avalable in two versions :
          - closed dial
          - open dial, visible mechanism
Not for use above 900m.

• " Hi-Sensitive " double capsule mechanism : movement of the hand amplified 2.2 times
         - Delivered with its "numbered control certificate", in accordance with the NFL00-15 standard: each barometer is controlled on 3 points, the tolerance between the pressure read and the real pressure must be less than 0.2%.      
Not for use above 600m.
