APPARATUS AND METHOD FOR LINE PLACEMENT

摘要

A line shooting air gun (10) that carries a line (150) down a conduit by creating a turbulent air flow in the conduit that keeps the line away from the drag inducing conduit sides. The turbulent air flow is created by a valve body (26) that reflects the air flow a number of different times, uses at least two chambers for compression and reflection, provides an unbalanced flow of air and angles the air flow around a venturi (110) breaking up any smooth flow. The line is carried by the turbulent air flow. An air drag system creates a serpentine line path producing air flow changes. A backpack with a rigid frame is provided for carrying an air tank.
