The 500g Turbojav weights 500 grams and is 42” long. USA and Canadian middle school as well as South African primary and Peru secondary school athletes use this weighted Turbojav. As the length starts to increase the difficulty of the throw increases as well. This is a great implement to use to start with before you are introduced into the TurboJavelins and real Javelins.
