Customised Control Options

The Benoit Light Assist 3 XL is built to adapt to your specific needs. Choose the control configuration that works best for you and your companion:

Attendant Handle Control (Standard): Puts the power literally at the fingertips of the person pushing. Ergonomic throttles on the push handles make inclines and long distances feel effortless.
Dual Controls: The best of both worlds. This setup allows both the wheelchair user (via joystick) and the attendant (via handle throttles) to operate the unit, making shared navigation seamless.
User or Attendant Control: Ultimate flexibility. This option allows you to toggle control entirely between the user and the assistant, perfect for those who want independence in some environments but a helping hand in others.
