The Rig Ring is an electronic 120DB whistle and blinking light that combines handheld functionality with remote control capability. The device can be used as a handheld device or can be fixed to an object or load and activated remotely. Excellent for traffic control, alerting civilians, or identifying danger overhead. 

The Rig Ring is intended to be fixed to an overhead load by the certified rigger, while the rigger is communicating with the crane operator via radio, the rigger can activate the Rig Ring whistle remotely. As the load travels across the jobsite to the landing location, the receiving rigger can remotely deactivate the Rig Ring whistle prior to landing the load.
