ABSTRACT:
An injecting dart having an improved barb design and aerodynamics is disclosed. The dart (10) preferably includes a stainless steel needle (12), and a body having a forward section (14) and a tail section (16). A narrow shaft (11) contains and supports the needle (12). The shaft (11) includes an integral, circumferential barb (24) which maintains the dart (10) in the hide of the animal until the dart's contents are fully discharged. The tail section (16) includes several fins (17) to improve aerodynamics, and a plurality of vent holes (38) to permit free movement of the dart's piston, thereby ensuring complete and rapid delivery of the liquid to the animal.
