Abstract: A pressure testing device comprising a connector adapted to engage a gas line containing a gas supply under pressure is provided. The pressure testing device includes a measuring device and a compressible pump. The measuring device operably communicates with the connector and is responsive to variations in pressure of the gas supply. The compressible pump has an input port and an exhaust port. The input port is adapted to receive ambient gases and the exhaust port is adapted to communicate with the measuring device for delivering ambient gas pressure to the measuring device.

Abstract: A portable Golf Swing Practice Device designed to train the Golfer in how to develop a full swing. This device responds to a full swing by returning the tethered golf ball to the original general tee off area or beyond when struck with the golf club in the correct fashioned, a full swing. The tethering is accomplished by the use of ground attachment, a dacron line and a nylon stretch cord attached to a golf ball, assembled in such a fashion as to allow consistent repeated use. By seeing these results the Golfer can develop a full swing which in turn will develop a better Golfer.
