Product Description
Shimano 10AQG Counter Gear (A) (TGT0532)
The Shimano 10AQG Counter Gear (A) is a precision-engineered internal component vital for the accuracy and functionality of your reel's line counter system. As a primary gear in the counter assembly, it transfers the rotation of the spool to the mechanical display, allowing anglers to track depth and distance with surgical precision.
This gear is manufactured from high-impact composite materials designed to withstand the repetitive stress of trolling and deep-water drops without stripping or slipping. If your line counter is skipping, showing inaccurate readings, or has seized entirely, the Counter Gear (A) is often the primary part requiring replacement. Replacing it ensures your lure stays in the "strike zone" by providing consistent, reliable depth measurement.
