This is a lightweight modular Discus Throw Circle.
Using keyed foam mats we cut out the proper size 2.5-meter throwing circle. There are 16 segments to the circle. We used a large laser router to cut a smooth accurate circle to the proper size. The pads lock together to form the throwing circle. We use dumbbell weights to hold the circle down or you can use any heavy object on two or more of the segments. The mats are heavy-duty 3/4 inch thick. Circle is accurate to within .5 diameter due to expansion and contraction of foam. We get material in 3 different colors and depending on availability the one shipped may be sky blue, silver/grey or black,
0, 90, 180 270, are marked on four segments to give visual to the proper foot placement for turns. Depending on availability they will be on contrasting segment colors or labeled in contrasting ink.
