brand new and high quality. The phishing alarm has a buckle on both sides, which can be directly placed on the fishing rod, and the line can be passed through the groove. When the fish bites the hook, the pull wire and the return line signal are generated, and the fish line is transmitted, and the switch on the alarm device is immediately triggered, and the power is turned on to make the sound and light alarm. At the lower end of the alarm, a power-off button switch is specifically set. When the fish is closed, the power can be disconnected as long as the alarm is off the pole, which can effectively protect the battery life. Features: 1. Simple to use, clip the alarm on the fishing rod, and open the power switch alarm device on the line to fish. 2. The buffer alarm is more accurate. 3. The buckle prevents the alarm from falling into the water. 4, The alarm light is very bright, clearly visible 100 meters away, easy to fish at night.
