The Boomerang is a remote controlled trolley return system designed for zip lines built over terrain that makes it inconvenient to return the trolley to the origin point. If you're planning on building a zip line that runs over water, rough terrain, or sits too high for a regular trolley walk-back, then the Boomerang is for you.  The Boomerang is designed for zip lines with a 6% slope or less.  Soaking wet zip lines can impact the Boomerang's ability to travel up the line.  Best when used in dry weather.

The Boomerang is not designed to carry a passenger up the zip line.  Max weight is 10lbs when the motor is moving the trolley up the line. The Boomerang is patent pending.
