Abstract: Three versions of a mobile launch support are each adapted for use with one or more launching devices which propel clay pigeons into the air for target practice. A preferred version of the invention provides a horizontally oriented insert tube, having a diameter sized for insertion into the receiver tube of a vehicle's trailer hitch. A vertical support tube extends vertically from the end of the insert tube. An attachment tube, extending perpendicularly from the vertical support tube, allows the vertical support tube and the insert tube to be connected during use, and separated for shipment or storage. A support plate assembly, carried by an upper end of the vertical support tube, provides a level surface upon which a launching device may be rigidly attached. An adjustment tube is telescopically slidable within the vertical support tube. The adjustment tube is slid within the support tube until a foot plate, carried by a lower end of the adjustment tube, is positioned on the ground.
