The Ultimate Vibra-Led Bite Alarm is a compact and effective bite alarm designed specifically for the mobile angler. This handy tool is easily attached to the blank of your rod with the adjustable mounting strap. As soon as the rod vibrates on a bite, the Vibra-Led emits both a sound signal and a blue LED light, so you won’t miss a bite – even in the dark! The bite alarm runs on three included LR44 batteries and is ideal for predatory, trout or whitefish fishing. Light, quick to mount and highly effective!
