Spotters were small vehicles used during spice mining on the planet Arrakis. Their job was to watch for wormsign, and report to the carryall so that the spice harvester could be lifted to safety.
They were also used to locate spice blows on the surface for harvesting.
Spotters were either land vehicles or airborne. Usually, both were employed during spice mining. They were co-ordinated by a man aboard the harvester, who was referred to as spotter control.
