There are a number of reasons the line might be breaking more often than expected. Here are a few, with tips to prevent it.
1) Make sure you're using the tethers between the stake and the pulleys (and drive) Tip: You can use a loop of the line for a tether as seen in the video below 👍
2) Weather can cause the line to deteriorate more rapidly We recommended setting up and taking down the course after each use.
It's fine to leave the field pulleys staked in place - but the main drive and remote controller can NOT be left outdoors when not in use. It pays to wind up the line and bring it inside with the electronic equipment.
