The Spar 300 represents a comprehensive approach to surveying and mapping underground utilities. It is fully integrated with the Trimble Access surveying environment and operates seamlessly with Trimble GNSS receivers and may be used with Trimble Total Stations.
The Spar employs a set of magnetic field sensors to accurately measure the 3-D vector to an underground utility.
Automatically combines this vector with absolute positions obtained via GNSS or other survey methods to obtain the 3-D coordinates of the utility
The Spar’s novel approach allows it to measure the 3-D vector from any vantage point within range
Its built-in acceleration and magnetic sensors allow it to operate in almost any position
It offers two distinct operating modes, line and sonde, extending its capabilities to most surveying situations
The Spar 300 is usually mounted on a survey pole and is the right tool for utilities within a radial range of approximately 10 ft. (3 m)
In a typical cable or pipe survey the Spar is mounted vertically on a survey pole directly below the GNSS receiver
Spar 300 Utility Mapping System contains; Two Li-Ion, 4Ah batteries, travel charger (AC) Two mounting spuds for mounting on quick release brackets CD.
