<p>A fish strike signaling device suspended from a fishing line which comprises a carrier (2), a weight (3) adapted for movement with respect to the carrier (2) and at least one variation sensor (4) arranged between the carrier (2) and the weight (3) and connected to an evaluating and signaling unit (5). The weight (3) is mounted for longitudinal movement on the carrier (2) and engages a variation sensor (4) or is attached to the carrier (2) by means of a horizontally disposed leaf spring (21) or by means of a vertically disposed tension/compression spring the second end of which is secured to the carrier (2). The variation sensor (4) may be a pressure fluctuation sensor, a magnetic field transducer with the weight (3) being a permanent magnet, or a capacitane transducer.</p> |
