Abstract: A projectile launcher includes a barrel mount, a tubular barrel, and a biasing member disposed in the barrel. The barrel mount can assume a barrel-securing configuration and a barrel-releasing configuration in which the barrel is longitudinally movable relative to the barrel mount from a forward position to a rearward position. The biasing member is compressible from an initial relaxed position to a first compressed position with the barrel in the rearward position, and to a second (further) compressed position the barrel in the forward position. The projectile can thus be launched at different speeds according to the barrel position. The launcher may also include a trigger release, a handgrip, and indicia markings on the barrel to denote approximate launch distance or other information. Optionally, the projectile is attached to a lead line that loops over a tree branch upon launching, such as for suspending a food container at a campsite.
