A portable device for launching a plurality of retriever dummies is described. The device is light-weight, portable, can be remotely triggered, and requires only a single person to operate. The device has a plurality of legs secured to a main beam and at least one strut extending from the main beam. The legs are preferably articulated and can function as struts. Elastomeric bands extend from a basket to the strut, through a pulley, and back to an anchor. The bands are stretched so that the basket can be fastened to a release mechanism. A retriever object can be placed in the basket. An operator can distance himself from the device and, using a remote control, disengage the fastener from the release mechanism so that the object is launched. The release mechanism is capable of retaining an elastomeric band under high tension while permitting its release using a low voltage electric motor.
