We also offer support for left-handed models. If you prefer a left-handed model, please specify this in the transaction message after purchase. Unlike the fixed type often found in pre-made products, this allows you to adjust the magnetic brake while fishing. Also, the line alarm can still be used after installing this product. Why not aim for ultra-long casts with a contactless magnetic brake instead of the centrifugal brake that uses friction? (It can also be used in conjunction with a centrifugal brake) You can find your preferred setting because it is infinitely adjustable by turning the screw. This product utilizes existing holes and the frame, so there is no impact on the reel body, such as drilling. Operation has been confirmed only on models with a line alarm for the Ambassador 6500, so we do not know if it is compatible with other models. Included items: Base parts, 6 magnets, adjustment screw, spacer, E-ring *Please note that there may be some minor imperfections or color variations due to 3D printing. Also, because we are constantly making improvements, the shape of the product may differ from the photos. We are not responsible for any damage or breakage to the reel caused by using this product. Please purchase with the above in mind.
