ADJUSTABLE SENSITIVITY: These electronic fishing bite alarms are designed to alert you when a fish is hooked. The sensitivity can be adjusted by changing the angle of the alarm, helping to reduce false triggers caused by strong currents or wind. Ideal for use with multiple rods, they help identify which rod has a bite. LOUD BLE ALARMS: When a fish bites, the alarm emits an 80-decibel sound to get your attention. This ensures you won't miss a bite, even when you're occupied or at a distance. Note: Volume is not adjustable. WIDE APPLICATIONS: With a 0.4 inch (1 cm) sensor opening, these alarms fit most fishing rods except those that are extremely thin. Suitable for various fishing styles including sea fishing, ice fishing, fly fishing, trout fishing, and pier fishing across different environments. A great gift for fishing enthusiasts.
