Telescopic 2 m and 3 m ranging rods for land surveying — portable, durable, and visible at distance for survey parties across Northeast India's plains and hill terrain.
A ranging rod is the surveyor's line-of-sight target — a brightly banded pole planted vertically at a survey station so it can be sighted from the instrument position hundreds of metres away. Without ranging rods, a surveying party cannot establish a straight traverse line, set out a building's baseline, or align a road or pipeline route across open ground. The alternating red and white 0.5 m bands serve the double purpose of making the rod visible from a distance and providing a scaled reference for rough distance estimation and rod reading in levelling operations.
Multi Trade Combines stocks 2 m and 3 m ranging rods in both fixed and telescopic versions. The telescopic design collapses the rod to a fraction of its survey length, making it practical for survey parties operating in Northeast India's hill states — Nagaland, Manipur, Meghalaya, Mizoram, Arunachal Pradesh — where road access to survey stations is limited and equipment must be carried on foot between points. Fixed rods are preferred on plains traverses in Assam where vehicle transport to each station is practical.
Ranging rods are used in conjunction with auto levels, digital theodolites, total stations, and dumpy levels — the core optical instruments for topographic and engineering surveys. In chain surveying (still widely used for smaller rural surveys in Northeast India), ranging rods are used alongside the 20 m or 30 m survey chain and cross-staff to lay out chain lines and set up offsets. For set-out work on building sites, they are used with a boning rod and level to establish grade and formation heights.
Multi Trade Combines also supplies prismatic compasses for bearing measurement, plane table and alidade sets for field mapping, and tripods for total stations and auto levels. A complete survey party kit — instruments, staffs, rods, tripods, and accessories — can be sourced from a single counter visit at our Guwahati showroom, with delivery to survey project sites across the Northeast.

A ranging rod is a straight rod, typically 2 m or 3 m long, painted in alternating red-and-white bands of 0.5 m each. It is planted vertically at a survey point to make that point visible from a distance, allowing the surveyor at the instrument station to align the theodolite, total station, or auto level with targets across open ground. Ranging rods are used to establish straight survey lines, to mark chain survey stations, to set out building corners, road alignments, and pipeline routes, and to provide a visible target in optical levelling.
A fixed ranging rod is rigid and accurate but requires a vehicle to transport on long survey traverses. A telescopic ranging rod collapses to approximately half or one-third of its extended length, making it portable in a backpack or van alongside theodolites, levels, and prisms. The telescopic variant is especially valued for survey parties working in remote hill terrain in Nagaland, Manipur, Meghalaya, and Arunachal Pradesh — where long hikes between stations make carrying full-length rods impractical. Accuracy is maintained because the extended sections lock firmly at the full calibrated length.
