Instructions
Place GMB on the ground with respect to the place where the ball will be hit so that the player will be able to check that the nylon line can pass freely through the eye on the guide and control rod and prevent it from being handled by another person. Simply press the ON button to activate GMB. Following the “autotest”, the total number of drives hit to date is displayed on the screen, and the nylon line with the tethered ball is released.
Next, release the ball from the holder on the back case. Release the guide and control rod from the carrying holder on the bottom of the case. Insert the three-section telescopic laminated guide and control rod into the opening on the bar, and fix into place at the maximum length so that the nylon line passes freely through the eye on the guide and control rod in the direction of the drive. Set up time lasts no longer than 15 to 20 seconds, and if factory-set values are used, the simulator is ready for immediate use.
The guide and control rod serves not just to eliminate any impacts while the ball is slowed and to make it easier for the ball to return over any obstacles, but also to turn off the automatic rewind and to return the ball after it is caught on an obstacle. After the ball is let loose from the obstacle by simply moving the guide rod to the side on the left, activate rewinding the nylon line to bring the ball into an ideal position.
A coloured laminated peg stored in the holder as well as the guide and control rod help prevent the nylon line from getting into an unsuitable position. The peg is pressed into the ground at least 50 cm between the mat and GMB, in the direction of the drive. The nylon line is placed around it or the peg is simply laid in the same place on the line before the drive is hit.
Once practice has ended, fold the telescopic guide and control rod, insert it back into the carrier holder and put the balls in the ball holder. Press and hold the red OFF button to slowly rewind the rest of the nylon line and after bidding a pleasant day displayed on the screen, the simulator automatically turns off.
Using screws and openings to anchor the device to the ground 
with metal hooks (included), the base construction with adjustable legs allows the simulator to be set up easily, even in very rough terrain. A ball joint allows the simulator case to be held in a position that is approximately horizontal to the ground (check the recessed level). These movable parts on the simulator allow the user to train drives from unusual positions.
Being able to use GMB in various weather conditions, playing into water, sand, snow etc. can help not just beginners, but also club players extend the active season at times when the terrain at golf courses does not allow for golf ball collectors to be used on extensive teeing grounds.
To prevent the reading sensors from becoming soiled, there is a brush located at the end of the guide and control rod.
