Tri-Site supplies, hires and supports a carefully selected range of professional survey equipment - chosen for real-world performance, not spec sheet numbers. With offices in Ripon, Glasgow and Reading, we work with organisations across the UK from independent practitioners to Tier 1 contractors, backed by expert advice, hands-on demonstrations and a team with genuine field experience behind every recommendation.
What we supply:
→ High-precision GNSS sensors & RTK rovers - survey-grade positioning for any environment, including GNSS-denied and obstructed areas.
→ SLAM scanners - handheld walk-and-scan systems producing real-time georeferenced point clouds, Gaussian splat, OBJ and intensity outputs from a single pass. No tripod. No targets. No post-processing.
→ Machine control - 3D guidance systems for excavators, available for purchase or hire with full installation and commissioning by our experienced team.
→ Marine & hydrographic equipment - unmanned surface vehicles, multibeam and single-beam echosounders, and ADCP systems for bathymetric and hydrographic survey work.
→ UAV systems - drone and airborne LiDAR platforms for aerial survey, mapping and inspection.
→ Data collectors & controllers - rugged tablets and controllers built for professional fieldwork.
→ Equipment hire - flexible short and long-term hire across all equipment categories.
What we do beyond equipment:
