SPAR 300

SPAR 300 - Surveying and Mapping of Underground Utilities:     Datasheet

• The Spar 300 represents a comprehensive approach to surveying and mapping underground utilities
• It is fully integrated with the Trimble Access surveying environment
• Operates seamlessly with Trimble GNSS receivers
• 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

• The surveyor monitors the display continuously, using the on-screen indicators to maintain casual contact with the utility center line
• Measurements may be collected automatically at fixed intervals or with single-shot measurements at selected locations
• The pole may be equipped with a survey wheel for convenience
