Offered here is a used Spectra Precision Promark 220 GNSS receiver, a compact GPS/GLONASS surveying system designed for centimeter level positioning in topographic and boundary survey applications. This unit has been tested for satellite acquisition and data logging performance and is confirmed to operate normally. It is a favored choice among smaller survey outfits looking for capable static and RTK positioning without the cost of newer multi-constellation systems.

This used receiver includes its standard antenna and has been functionally verified for signal tracking and data storage. It suits survey firms, GIS mapping crews, and agricultural or utility companies that need dependable GNSS positioning on a budget.
