This sensor detects the tilt of the fishing rod during night surf fishing and alerts you with sound and light when a fish bites! A must-have for surf fishing! Features: * Loud alarm volume * LED lamp (white) flashing specification - do not look directly at it ⚠️ The body is made of break-resistant ABS resin, making it resistant to impacts such as drops. This depends on the conditions of use. The sensor is IPX4 water-resistant, so you don't have to worry about water getting in on rainy days and the sound not working, but you can also put it in a plastic bag, etc. ⚠️ IPX4 water resistance: Safe to touch with wet hands, and withstands some rain and splashes. Many products, such as mobile phones, digital cameras, and disaster prevention radios, fall into this category, and it is the minimum level required for kitchens and outdoor activities. It is tested by spraying water from any direction without harmful effects, with a water flow of 10 liters/minute in all directions from a height of 300-500mm for 10 minutes. Splash-proof type. Not sold in fishing tackle stores. Clip-on type for easy attachment and detachment. The sound and light can be heard and seen even in the sea breeze, but due to the handmade nature of the product, there may be slight differences in sound and light, so please understand. Uses 2 AAA batteries. Economical. How to use: The waterproof effect is improved if the side button is facing down. Pull out the sensor's pull-out pin, and the alarm and LED lamp will flash and sound when tilted (on). Pushing the pin in turns it off (off). Caution ⚠️ The pull-out pin does not come out completely. It remains attached to the main unit. Although the screws are stainless steel, applying a lubricant (such as silicone oil) to the bell, spring, and pull-out pin after fishing will prevent rust. The sensitivity of the sensor can be adjusted depending on the angle, so please adjust it each time you use it. #TamanSensor #HitSensor #AtariSensor #Tackle #Uchikomi (Surf Fishing)
