What We Use in the Field
Every instrument we use is chosen to provide maximum accuracy for the specific survey requirement.
High Accuracy
DGPS — Differential Global Positioning System
Standard GPS uses satellite signals that can have errors of several metres. DGPS corrects these errors using a network of ground-based reference stations, achieving centimetre-level positioning accuracy.
This level of precision is critical for surveys where the exact geographic coordinates of boundary points need to be legally documented, or where a survey must integrate with government GIS or land record systems.
- Large area boundary surveys
- DGPS surveys requiring coordinate data
- Infrastructure and development projects
- Sites where standard equipment accuracy is insufficient
Precision Digital
Total Station
A Total Station combines a theodolite (for measuring angles) with an electronic distance meter in a single instrument. It can measure horizontal and vertical angles as well as slope distances to a target with high precision.
Used for boundary marking, land subdivision, construction setout, and topographic surveys, the Total Station is the workhorse of modern field surveying — faster and more accurate than conventional chains and levels.
- Boundary survey and marking
- Land subdivision and partition surveys
- Construction setout and site surveys
- Topographic and contour surveys
Auto-Level
Digital Level
A Digital Level automates the height measurement process that traditional optical levels do manually. It reads a bar-coded staff electronically, eliminating human reading errors and significantly improving measurement speed and consistency.
For projects requiring accurate elevation data — such as drainage design, road profiles, foundation levels, and retaining wall planning — the Digital Level provides reliable, repeatable measurements across even long survey runs.

- Road and drainage level surveys
- Contour surveys and elevation mapping
