My daughter throws hammer and weight and the outdoor practice area only has a discus circle and cage. I made these so that she had the proper size circle for hammer and weight throw. They are light and easy to take with you and the pieces assemble quickly and are tight in the circle so they stay put.
It is light, easy to setup and take down and takes up minimal room.
When Gill and others are getting $600 or more for inserts that are bulky and don't transport well we tried to come up with something that a thrower could have at home or a school could afford and not break the budget.
This is meant for practice only and allows any thrower to have their own circle inserts to work with for under $100.
Also take a look at our practice Weight Throw bag and handle and our indoor outdoor Shot circle. We also have a heavy Hammer conversion ring that is as good or better than Gill and other. It weighs 53 lbs and can be left in the circle overnight. It can do double duty as an indoor shot and weight throw ring for indoor. $225
