Microcast Spool AMB2518TR Trout Special (Groove Depth 1.8mm) This is a Microcast spool for the ABU Ambassador 2500C series, a Trout Special model. The groove depth is 1.8mm, specifically designed for managed fishing areas and mountain streams. By making the groove shallower than the conventional model and adopting the TR specification, the outermost diameter of the spool has been made less inertial, allowing it to handle lighter lures. Also, even with the same weight, casting is possible with less force than the conventional model. This model also supports magnetic brakes, and the MicrocastBrake AMB2518 is the dedicated magnetic brake.
