While maintaining the performance of the conventional Prospect, the new Lake Biwa spec has been added to the 14lb and 16lb models that are commonly used with heavy caro line. The current Prospect model has a 300m spool and 75m x 4 markings, while the Lake Biwa spec model has a 330m spool and 110m x 3 markings, making it easy to use for those who use heavy caro line.
