Patchwork’s latest guidance unit is the BlackBox Go. It’s designed to be an easy-to-install and simple-to-use unit, says the Monmouthshire company. So the receiver, aerial and terrain compensator are all integrated and getting going involves setting the width, selecting the guidance mode and starting work. It can also be upgraded to the BlackBox Advance, giving advanced recording, headland warning and scope to use sprayer and spreader auto shutoff and variable rate application. It costs £1,475.
