A signal device for use in fishing includes an adjustable contact member and a slidable contact member which can be moved into contact with each other by a fish when striking the bait to cause energization of a relay means for controlling the operation of a buzzer and lamp system. A normally closed reset switch is provided for maintaining the energization of the relay means in case the two contact members are out of contact with each other so that signals from the buzzer and lamp system are continuously produced to positively warn of a hooked fish.
