We also offer production for left-handed models. If you would like a left-handed model, please specify it in the transaction message after purchase. By replacing all bearings with ceramic ones, even with an ultra-high-speed rotation type (when free) such as the level winder making 48 rotations, the brake can be applied to less than one rotation when the brake is set to MAX. When the brake is set to MIN, it was about 15-20 rotations. (Please consider this as a guideline) This product allows you to adjust the magnetic brake while fishing, unlike the fixed type often seen in products. Although the line alarm can still be used after installing this product, when the line alarm is ON, it often interferes with the line alarm's metal fittings, making it impossible to reel in by turning the handle. * While it can handle some line payout, please consider that it cannot be used as usual. By arranging the magnets in a stepped manner like terraced rice fields, we have improved the design to bring them closer to the magnets. 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 on Ambassador 6500 models with a line alarm, so we do not know if it is compatible with other models. Included items: Base parts, 11 magnets, adjustment screws, spacers, E-rings * Please note that there may be some burrs or color variations due to 3D printing. Please understand that we are not responsible for any incidents such as the reel being scratched or broken by using this product.
