The portable automatic golf ball teeing device is approximately 9 inches wide x 9 inches tall x 18 inches in length and is in the shape of a miniature golf bag. The device is portable and lightweight and can be operated using a/c or d/c current and will run several hundred cycles before requiring the battery to be recharged. It can accommodate approximately 3 - 4 dozen golf balls and has a unique feature that eliminates any type of ball jams. This simple design also guarantees 100% accuracy and placement of the golf ball onto the tee without a misfire and is height-adjustable for the various range mat and tee sizes. A recent simplified improvement has been developed to eliminate the manual height adjustment so that it will work on different mat thicknesses and different tee heights automatically. The distance from the device to the tee is approximately 14 inches. It works like this. The device is located to the tee at the specified distance. The balls are then loaded into the tray and the unit is turned on. The device then senses the absence of a ball on the tee and starts up. It places the ball on the tee automatically within 5 seconds, and then will be in standby mode until the ball is hit or removed from the tee again. This eliminates the need for the practice golfer to stoop over and place a ball onto the tee one at a time. When the ball is hit or removed from the tee the process is automatically repeated until all of the balls are used up. I also have a specially designed golf tee that will allow this device to be used on natural turf grass without the tee having to be reset due to being struck multiple times by a golf club. I have 2 designs that could be considered and either will work.
