We also offer production for left-handed models. If you wish to have a left-handed model, please specify it in the transaction message after purchase. Unlike the fixed type often seen in mass-produced products, this allows you to adjust the magnetic brake while fishing. Also, the line alarm can be used even after installing this product, and you can use all of the original functions. Why not aim for ultra-long casting with a contactless magnetic brake instead of a centrifugal brake that uses friction? (It can also be used in conjunction with a centrifugal brake) You can find your favorite setting because it is infinitely adjustable by turning the screw. This product uses existing holes and frames, so there is no impact on the reel body, such as drilling. Operation has been confirmed only with models equipped with the Ambassador 6500 line alarm, so it is not known whether it is compatible with other models. Included items: Base parts, 6 magnets, adjustment screws, spacers, E-rings *Please note that there may be some burrs or color variations due to 3D printing. Please note that we are not responsible for any damage or breakage of the reel caused by using this product.
