STEC SDi Pro Laser Visual GNSS RTK Receiver

The STEC SDi Pro Laser Visual GNSS RTK Receiver combines GNSS RTK positioning with long-range laser measurement and camera-based visual surveying. It is designed for measuring points that are difficult, unsafe or inconvenient to occupy directly, such as points across roads, behind fences or at elevated structures.

The red laser system uses Automatic Gain Control to improve distance measurement under different light conditions, while dual cameras support visual AR stakeout. With an internal 2 W radio and rugged IP68 construction, the SDi Pro provides a flexible solution for demanding surveying and construction projects. RTKSurvey supplies the STEC SDi Pro for professional field applications.
