Topographic Accessories

InfrastructureGeotechnical InstrumentationSurveying Equipment

The topographic accessories such as bolts, prisms, and targets are mainly used in topographic survey and monitoring. Reference bolts are threaded to accept optical targets. Rotary targets can be also mounted on a simple threaded bar or attached to an inexpensive “L” shaped bracket. The GMP104 equivalent to the Leica mini-prism provides good survey performance. Its aluminum bracket can be mounted and adjusted easily for 3D surveys. Topographic benchmarks and bolts can be supplied when topographic levelling is required. More info.↗
