MDXONE “OX” has a 16 feet retractable red tape/cord with two 12” bungee cords at the end to connect to the Backpack/harness attachment points.
With the retractable leash, you can now decide the distance between you and your student with a simple push on the stop/release button with your thumb.
Let your child go on his/her own. Press the stop button to slow him/her down, prevent a front edge or make them turn.
When hitting the stop button, the bungee cord will extend slowly which will not cause a jarring effect on the student. No more playing human yo-yo with your child.
There’s no lock button on the leash, only a stop button.
