VIBRAPHONE
Victim Location System
The ASB8-C vibraphone, known to rescue
teams all over the world, makes it possible to detect a victim buried
under rubble after a catastrophe and to find their exact position.
The slightest noise the victim makes
can be detected by this device, whose sensitivity is exceptional .
The vibraphone is fitted with an
adjustable filter which deadens the effect of dull noises like pneumatic
drills, lorries passing, etc.
The national reference guide specifies
that at least two electronic listening packs should be carried in
vehicles or with ‘rescue / clearance’ teams.
