Title: Fishing reel light alarm
Inventor: GILLIES IAIN
IPC: A01K89/00
Filed: 1986-06-06
Abstract: A fishing reel light alarm has an opto-electric indicator (5) which, when switched to the 'on' position, will emit light when supplied with an electric current by the electro-mechanical transducer containing piezo-electric material (9) through the twin wiring (6) when the spool of the reel incorporating the light alarm is made to rotate. The light alarm will therefore give a clear visual signal of a rotating fishing reel spool, as would be the case when a hooked fish began to pull line from the spool. As the light alarm does not require a battery or other external power source, it is eminently suitable for fishing reels, being virtually maintenance free while simultaneously increasing the fish catching effectiveness of the reel incorporating the alarm. The external appearance of the reel incorporating the light alarm is enhanced, increasing its technological attractiveness to the angler for both practical and aesthetic reasons. <IMAGE>
