GOLF MOBILE BOOMERANG (GMB) as the name suggests is a mobile machine of the following proportions: 340x280x200mm (13.4 x 11 x 7.9 inch), weight 4,6kg (10.2 pounds), powered by a build-in 12V battery (fully charged lasts approximately 900 shots). It enables its users to practise hitting a standard golf ball attached to the cord in limited outdoor space (from 25m) all year round. The golf ball is slowed down during the flight and stopped in the distance, which is set on the Display by the golfer in advance (maximum distance 60m), and automatically returned to the starting position. The real distance of the shot is then calculated, based on the ballistic curve of the ball, starting speed of the ball and the golf club used, and displayed in metres on the build-in Display, together with the starting speed of the ball and number of hits at the current training session. By simply switching, the
distance and the starting speed of the ball could be displayed in yards and miles per hour. Those functions are possible due to the build-in computirised electronic commanding system, whose software evaluates and synchronizes the single operations through the sensors, servo-mechanism and an electromotor. The system also possesses the extra capacity for the currently developed and already patented GOLF MOBILE GAME.

By pressing the buttons on the control panel the distance of the shot, re-winding speed (depends on the terrain as well), club calibration, club selection, etc. can be selected. The selected data is shown on the Display. The specially developed software enables to select specific corrections by pressing the MENU button followed by pressing some of the additional buttons.

The connection of the ball with the 60m long cord unwinding from the build-in spool influences the flight of the ball in the beginning only minimally, which enables the player to control the direction of the ball very efficiently. A ball-shaped stop inside the cavity of the ball was developed to stop the cord from forming loops during the shot. (The stop is a part of the patent protection.)

The GMB must always be positioned in such a manner that the player is able to control free movement of the cord through the loop of the Leading and Controlling Rod before each shot, and is also able to stop an unauthorized person manipulating the GMB. To activate the GMB, press and hold for couple of seconds the ON button. After the AUTOTEST the total number of shots will be shortly shown on the display, and the cord with the attached ball will be freed. The ball must be freed from the Spare Ball Container at the back of the GMB’s Body, and the Leading and Controlling Rod from the transport holder at the bottom of the GMB’s Body. Insert the three-part telescopic fiberglass Leading and Controlling Rod into the Lever Hole, and secure it at its maximum length. The cord must be able to slide freely through the loop in the direction of the shots. Preparation time does not exceed 15 – 20 sec providing the factory settings are used.

The Leading and Controlling Rod eliminates possible
collision of the ball during the slowing down period,
contributes to easier maneuvering of the returning ball through the terrain obstacles, and enables automatic disconnection of the rewind, should the ball get caught. When the ball is freed from the obstacle by moving the Leading and Controlling Rod to the left, the re-winding is re-activated and the ball returned into the ideal starting position.

To adjust an undesired position of the cord a coloured fiberglass peg (stored in the transport holder together with the Leading and Controlling Rod) can be used. The peg is inserted into the ground between the GMB and the hitting area. The cord is led around it. During a windy weather the peg could be placed on the cord at the same position.

Stability is ensured by the Circular Legs, which can
be vertically adjusted. In very declined terrain the
legs could be secured into the ground with the provided pegs, which are inserted into the ground
through the holes in the Circular Legs. (The pegs
are part of the standard accessories, and are stored in the slots under the Spare Ball Container.)

Place the GMB as close as possible to the horizontal position. The horizontal position of the GMB could be checked by the build-in round spirit level, which is part of the Display. The exact horizontal position in
every terrain is possible due to the Ball Joint and the Safety Screw and regulating nut covering the Ball Joint. Before inclining the GMB’s Body, the screw of the Ball Joint must be loosened to the left and the egulating nut to the right. This enables inclining and subsequent alancing of the GMB’s Body into approximately horizontal position. The position of the joint must be secured by turning the screw to the right. The GMB could be used in an uneven terrain as well as to practise shots from unusual positions, which is not offered even at the top golf ranges.

At the end of the practice session disassemble the telescopic Leading and Controlling Rod and store it in the transport holder. Put the ball into the Spare Ball Container. Press and hold the OFF button until the cord is automatically re-winded, and with a “Have a nice day” message the GMB switched off.

The possibility of using the GOLF MOBILE BOOMERANG in different climatic conditions (e.g. play into a water, on sand, on snow) could prolong the active season for beginners as well as advanced club players. They can practise golf in such times when the terrain of the golf ranges does not allow training and picking up the balls by machines.
