Carp Sensor: A fishing alarm that notifies you of a bite. (Please note that we will perform a simple inspection, so we may check the product once.) We also have a variety of other products available, so please take a look at our other listings and bid on your favorites. (It's easier to see them if you sort by price.) This listing is for one item, so please make sure you don't make a mistake. When a fish hits, the alarm and LED will notify you when the line is pulled. You can know when you have a bite without missing it, even if you are doing something else or sleeping. The sound is the same as a child's safety buzzer, so you can hear it clearly.
