Sonar device (1) for detection of underwater objects, said sonar device (1) comprising:
- a body element (2) comprising a piezo electric element (3), and
- a holder (4) for holding the piezo electric element (3),
- wherein:
- said holder (4) has a planar portion and three to twelve arms (40, 41, 42) extending at a right angle relative to said planar portion, each of said three to twelve arms (40, 41, 42) having a U-shaped profile defining two separate engagement points (410a, 410b) and a space therebetween,
- said holder (4) is arranged to center the piezo electric element (3) within said body element (2),
- said holder (4) is arranged such that the piezo electric element (3) is held firmly in place by said three to twelve arms (40, 41, 42),
- said holder (4) is arranged to provide for omni-directional detection, and
- said holder (4) engages the piezo electric element (3) at three to twelve separate engaging areas (400, 410, 420) defined by said three to twelve arms (40, 41, 42) and further separated by a non-engaging area between each adjacently positioned of the three to twelve separate engaging areas (400, 410, 420).
