10 times the durability! (Compared to previous models)

The new integrated construction method used provides shock resistance of 10,000 m/s2 (approx. 1,000 G in X, Y and Z directions for three times each), and vibration resistance clears durability tests of between 10 and 500 Hz (3 mm 0.118 inamplitude in X, Y and Z directions for 2 hours each). In addition, resistance to impulse noise is approx. three times greater than for previous models.
