A hand-held apparatus for projecting a line across an intermediate span includes a launching tube having one end connected to a source of propellant gas energy for launching a projectile, the other end forming an open muzzle adapted to receive and fire a line deploying projectile. The projectile is releasably attached to one end of the line attached to a source of line connected to the launch tube and containing a supply of line to be payed out during the flight of the projectile. An axially-mounted laser sighting device connected to the launch tube for sighting the tube in on a remote target for the projectile is also provided.

[ What is claimed is:] [1.]1. A hand-held pilot line deploying tool for use by an individual for projecting a pilot line across an undetermined span comprising:(a) a launching tube having a chamber and an associated source of energy for launching a projectile from the tube and a muzzle end adapted to discharge a line deploying projectile;(b) a projectile device to be launched from said launching tube for carrying one end of said line across said span;(c) a source of lightweight pilot line connected to said launching tube and containing a supply of lightweight line to be connected to said projectile and payed out during a flight of said projectile;(d) an axially-mounted sighting device connected to said launching tube for sighting said tube in on a selected remote target for said projectile; and(e) a device for triggering the launching of said projectile from said muzzle.
