A beeline is a fast-burning detonating cord or fuse containing a continuous core of explosive powder. Shotfirers use it to link multiple explosive charges together, ensuring they detonate in a rapid, synchronized sequence. The predictable burn rate allows for precise timing in complex blast patterns.
