Line-Launcher description: pocket/backpack (al1) vs backpack-mounted (b07)

Device that launches rope, string or associated fibers, like krypto-fibers. Gets reduced to a very compact size so can be stored in a pocket or backpack. Rob always carries one with him.

Backpack-mounted, rapid launcher of rope, wire, krypto-web and other similar products. Projectile distance of up to 500 yards. Employs CRT (Coil-Release Technology) which means the thing to be launched (i.e. the rope or wire) needs to be advance wound around a tightly sprung coil within the primary release chamber itself.
