While the GPS Locator allows you to pinpoint the position of an object (such as a lateral move irrigator, drag line or weather station), the digital compass indicates the direction of movement - which is particularly useful for monitoring the uniformity of the movement of a centre pivot, as any change in speed shows as a change in slope of the graph.

Its extremely low power consumption and robust poly-carbonate housing, make the device ideally suited for permanent outdoor operation. A Goretex breather vent provides pressure compensation; the aluminium arm allows mounting on Adcon’s standard aluminium poles; and a 4m cable with Adcon’s standard 7-pin connector makes the device compatible with most Adcon RTUs (A723, A733, A753 and A755)
