The Aero Technium 12000 XTB MGS is the ultimate distance casting reel for those who want the very best. It's a reel designed without compromise and literally includes the best of everything Shimano has to offer in a sleek futuristic body that is finished almost totally in black with subtle chrome detailing. The magnesium and CI4+ body components produce remarkable lightness, which in turn increases rod speed when casting. The combination of the AR-C spool, Aero Wrap II and super slow oscillation (approximately 100 turns of line per full oscillation) produces the most perfect line lay and the inclusion of X-ship engineering ensures maximum cranking efficiency when playing fish. A prestigious 8 Shielded A-RB bearings, plus a roller bearing, makes this model the smoothest Shimano 'Big Pit' you can own and a few turns of the slim profile handle reveals it's true pedigree. The inclusion of a line guard guarantees trouble free performance and prevents any chance of the line getting under the spool.
