- Interchangeable left-right design for both left- and right-handed anglers. Easily switch to match your preference and fishing style. - Durable fishing equipment: alloy body with EVA material for long service life. Left and right interchangeable spinner provides flexible setup. - Balance block system supports different line-drawing habits and helps prevent scattering of fishing lines and gear, improving line control during retrieval. - Loud metal bite alarm clearly signals when a fish pulls on the line, aiding timely response. Use scenarios: - Bank or pier fishing: switch quickly to the preferred hand orientation for comfortable casting and retrieval. - Boat or shared-use setups: rotate the reel to suit the user, reducing fatigue during long sessions. - Conditions with tangling risk: use the balance block to maintain orderly line lay; the audible alarm helps detect bites in low visibility or distant bites.
