Acoustic bite alarm with two alarm modes, bright seven-color LED, adjustable strap, splash-proof housing, and adjustable volume — designed to make bites easier to detect day or night and to fit virtually any rod. Key benefits Detect subtle nibble vs aggressive strike: Two alarm modes let you distinguish bites. Intermittent mode emits a subtle tone for light nibbles; continuous mode sounds a stronger tone (one-second duration) for aggressive bites. See and hear alerts from a distance: A high-brightness control light flashes when the alarm activates. The seven-color LED is highly visible for night fishing and low-light conditions. Reliable in real use: Loud, clear audio output with adjustable volume and a splash-proof housing gives audible alerts and protection near water. Fits any rod, stays put under strain: The adjustable strap secures the alarm to rods of different diameters and shapes and holds during strong pulls. Core features and performance Alarm modes: intermittent (subtle nibble tone) and continuous (strong one-second tone for aggressive bites). Visual alert: high-intensity flashing control light with seven selectable colors for clear night visibility. Audio: loud, clear sound with adjustable volume to suit location and personal preference. Durability: splash-proof housing protects the unit from water spray and light rain. Compatibility: adjustable strap accommodates thin and thick rods, round or tapered blanks, and locks in place so it does not fall off during a strong bite. Practical use scenarios Night bank or pier fishing: Attach the alarm to your rod, set a bright LED color, and fish multiple rods with confidence — you’ll see the light and hear the alert even in the dark. Boat or shore fishing in variable weather: The splash-proof housing and adjustable volume ensure you don’t miss bites when conditions are wet or wind increases ambient noise. Multi-rod or unattended setups: Use intermittent mode to monitor for light takes and switch to the stronger one-second tone for aggressive strikes, so you can prioritize which rod to attend first. What this solves Reduces missed bites by providing both audible and visual alerts. Simplifies bite assessment so you can react appropriately to light nibbles or solid strikes. Eliminates fit concerns by adapting to almost any rod profile and holding securely under load. Compatibility and fit Adjustable strap fits a wide range of rod diameters and shapes; secures firmly so the alarm remains in place even when a fish pulls hard. Designed for anglers who fish day or night and need clear, dependable bite indication without complicated setup. Simple to attach, easy to use, and built for on-the-water reliability — this acoustic bite alarm gives clearer alerts, better night visibility, and flexible attachment for most rods.
