Properly aligning guides can be one of the most tedious tasks when building a custom rod. The CRB Laser Alignment System features a reel foot mount mounted laser housing with vertical beam, leveling bubbles and reversible tape measure. Once mounted, a perfectly straight beam is projected down the rod all the way to the tip. The vertical laser makes aligning guides and butt wraps a snap. While fishing rod blanks are not as straight as a laser, this tool will greatly aid you in aligning your guides.
