m in length in this non limiting embodiment support block 36 has two additional mounting holes 35 formed in its top surface 31 these holes 35 are sized to receive and retain the outer diameter of portion 91 of the two uprights 90 additional conventional fastening means not shown similar to pin members 60 may be used to secure the uprights to the support block 36 in this embodiment holes 35 are located approximately two inches 5 08 cm from the outermost edges of the block 36 net 92 is coupled to and runs the length of crossbar 95 net 92 is a relatively fine mesh net allowing a user to easily see through the net 92 while effectively stopping the intended projectiles e g golf balls from passing through net 92 is generally rectangular in shape being approximately four feet 1 22 m wide and six feet 1 83 m in length this length allows net 92 to hang from crossbar 95 down to the ground as shown net 92 is located between the user and mirror assembly 12 and allows a user to hit standard golf balls toward the training aid 10 without the worry of ricochet or accidental miss hit balls going past the training aid 10 using standard golf balls also provides the positive training feedback of feel i e feeling the impact associated with hitting golf balls used on the golf course net assembly 18 allows the user to experience this tactile feedback while still providing the immediate visual feedback provided by mirror assembly 12 it should be appreciated that substantially any of the embodiments described herein can be combined to provide the user of training aid 10 with a number of training options for example and without limitation.
