There are certain features that are really useful in a bite alarm and this one has it all. It is easy to attach to the line, has an LED light and beeper to alert you when you have a bite. It will easily clamp onto the rod and you will be able to use it right away. It is very simple, nothing special needs to be done with it and so you can get using it right out of the box. It is small so easily portable and it will also be easy to store when you are not fishing. It is a low price but has a loud enough beep to alert even a sleeping angler that they have a bite!
