A method of lifting device load hazard avoidance is disclosed. In one embodiment, the method comprises determining a three dimensional position of a load hazard avoidance sensor unit coupled with a load line of a lifting device, the determining performed by a first global navigation satellite system (GNSS) receiver coupled with a housing of the load hazard avoidance sensor unit, monitoring for a load related hazard in a vicinity of a load coupled with the load line, the monitoring performed by a load monitor coupled with the housing and initiating at least one load related hazard avoidance action in response to a monitored occurrence of the load related hazard.
