ADJUSTABLE SENSITIVITY: These electronic fishing bite alarms are designed to alert you when a fish is hooked. The sensitivity of the fishing alarms can be controlled by adjusting their angle, which helps to exclude the effects of strong currents and wind. When fishing with more than one rod, these alarms help identify which rod has a bite. FINE WORKMANSHIP AND DESIGN: Well-built with a sleek, functional style. LOUD AUDIBLE ALARMS: When a fish bites, the fishing alarm emits an 80-decibel sound to get your attention. You won't miss a single bite, even if you're far away or occupied with other tasks. Note: Volume is not adjustable. WIDE APPLICATIONS: The alarm clip opening measures 0.4 inches (1 cm), compatible with many rod types, except very thin rods. Suitable for sea fishing, ice fishing, fly fishing, bass fishing, trout fishing, kayak fishing, and pier fishing in various environments. A great gift idea for fishing enthusiasts.
