This night fishing strike sensor detects the tilt of the rod and alerts you with sound and light! Essential for night fishing! Alarm sound LED lamp (white) flashing specification. Do not look directly at the light. ⚠️ The body is made of impact-resistant ABS resin, making it durable against 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. ⚠️ IPX4 water resistance: Safe to touch with wet hands and withstand some rain or splashes. Many products, such as mobile phones, digital cameras, and emergency radios, fall into this category, and it's the minimum level needed for kitchens and outdoor use. Protected against harmful effects from water spray from any direction. Tested with 10 liters/minute of water sprayed from all directions from a height of 300-500mm for 10 minutes. Splash-proof. Not sold in fishing tackle stores. The sound and light are designed to be heard and seen even in the sea breeze, but because they are handmade, there may be slight variations in the sound and light. Please understand. Uses two AAA batteries. Economical. How to use: Pull out the sensor's pull-out pin, and the alarm and LED lamp will flash and sound when tilted (on). Push the pin in to turn it off. Caution ⚠️ The pull-out pin does not come out completely. It remains attached to the main unit. The screws are stainless steel, but for the bell, spring, and pull-out pin, applying a lubricant (such as silicone oil) after fishing will prevent rust. Photos 3-4 are for reference. The sensitivity of the sensor can be adjusted by angle, so adjust it each time you use it. #TamanSensor #HitSensor #AtariSensor (Strike Sensor)
