Electronic bite alarms as used by carp anglers

A bite indicator is any signalling device (mechanical or electronic) used in angling which alerts the fisherman of what is happening at the hook end of the fishing line, particularly whether a fish has swallowed (i.e. "bite") the hook. It is the quintessential tackle used in bait fishing, which depends partly on luck and often requires unpredictable periods of time passively waiting for fish to bite the hook.


There are many types of bite indicators. Which ones work best depends on the type of fishing.

Bite alarms can range from simple devices with an on/off switch that do no more than indicate when the line moves over the roller, to more sophisticated devices with volume, tone and sensitivity controls. They are useful when fishing with more than one rod, and are commonly used when coarse fishing for carp. Whereas floats can be used as visual bite detectors, bite alarms are audible bite detectors. Although more expensive than visual devices, audible devices are popular as they do not require constant monitoring. They were invented by Richard Walker.
