Ever since its introduction in 2005, the Sentinel has been a vital lifeline for competitors in the Dakar Rally.
This clever piece of kit warns riders when they are within 656 feet of another vehicle, and therefore assists with the completion of safe overtaking moves. It's particularly helpful in low visibility conditions, such as the thick dust experienced during many Dakar stages. Situated beside the navigation panel or on the handlebars, it beeps and flashes to alert riders.
