Surveying equipment list: instrument names, uses and what a crew needs
Key takeaways
- A GNSS RTK receiver and a total station cover most day-to-day survey work between them.
- Levels remain the simplest way to transfer heights precisely over short distances.
- Accessories such as tripods, tribrachs and poles directly affect accuracy, so they deserve the same attention as instruments.
- Choose equipment by the survey type, the required tolerance and the site conditions, not by brand familiarity.
- Second-hand instruments can save money but need calibration checks and parts support before purchase.
What surveying equipment does a modern survey crew use?
A modern survey crew relies on a small core of surveying equipment: a GNSS RTK receiver for coordinates, a total station for angles and distances, a level for heights, and the accessories that hold them steady. Surveying itself is the measurement of positions, distances, angles and heights on or near the earth's surface, so every instrument answers one of those questions.
The exact kit depends on the work. A boundary crew, a construction setting-out team and a topographic crew share most of the same tools, but they weight them differently. The table in the next section is a practical list of surveying tools with names and uses.
List of surveying tools and instruments with their uses
The following list covers the survey instruments and surveying tools found on most professional crews.
| Instrument | What it measures | Typical use |
|---|---|---|
| GNSS RTK receiver (survey rover) | 3D coordinates from satellites, centimetre level with corrections | Topographic, boundary, stakeout, GIS |
| Total station | Horizontal and vertical angles plus distance (EDM) | Setting out, detail survey, control traverses |
| Theodolite | Horizontal and vertical angles only | Alignment, angle checks, teaching |
| Automatic or digital level | Height differences | Benchmarks, floor levels, drainage falls |
| 3D laser scanner | Millions of 3D points | As-built, heritage, volumes, BIM |
| Data collector / controller | Stores and computes field data | Running survey software in the field |
| Handheld laser distance meter | Short distances | Rooms, quick checks |
| Measuring tape and ranging rods | Distances, line marking | Offsets, short measurements |

Which survey instruments measure position, angles and heights?
The three main survey instrument families each solve a different measurement problem. Combining them is how a crew checks its own work.
GNSS RTK receivers
RTK (real-time kinematic) receivers use corrections from a base station or network to reach centimetre-level positions. Our E1 GNSS RTK receiver has a 1408-channel full-constellation engine, IMU tilt survey up to 60° and an IP68 housing, and it works as radio base, radio rover or network rover. GNSS is fast in open areas but struggles under dense trees and next to tall buildings.
Total stations
A total station combines an electronic theodolite with electromagnetic distance measurement (EDM), which measures distance from the travel of a light signal to a prism or surface. The STSA9 Android total station, for example, offers 2" angle accuracy and up to 1500 m reflectorless range. Total stations work where GNSS cannot: indoors, in tunnels and under canopy.
Levels
Automatic and digital levels give the most precise height differences over short sights. They are covered in our guide to auto levels, laser levels and total stations.
Survey supplies and accessories you should not overlook
Accessories carry the instrument and define the point being measured, so a poor tripod or out-of-adjustment tribrach adds error to every reading. Survey supplies and survey accessories are also the items crews replace most often.
- Tripod – aluminium or wooden legs with a 5/8" × 11 head thread. Our aluminium survey tripod extends from about 90 to 158 cm.
- Tribrach and adapter – a levelling base with three foot screws, a circular vial and an optical plummet for centring over a mark.
- Survey pole (survey stick) – a telescopic range pole with a bubble for GNSS rovers or prisms; a bipod holds it steady.
- Prisms and targets – reflectors for total station measurement.
- Controller bracket – clamps the data collector to the pole.
- Field supplies – survey hammer, nails, pegs, marking paint, flagging tape, field book and spare batteries.
Our accessories guide to tripods, tribrachs and prisms explains how to check each one.
Basic surveying equipment for each type of surveying
The basics of surveying are the same everywhere, but each type of survey leans on different tools. Use this as a starting checklist.
| Survey type | Core equipment | Supporting tools |
|---|---|---|
| Topographic survey | GNSS rover, total station | Controller, prism pole, level for benchmarks |
| Boundary and land subdivision | GNSS rover, total station | Metal detector for finding marks, survey markers, hammer |
| Construction staking | Total station, GNSS rover | Pegs, paint, laser or auto level |
| As-constructed survey | Total station, laser scanner | GNSS for control, targets |
| Bulk material and stockpile survey | GNSS rover, laser scanner | Pole bipod, volume software |
| Utility mapping | GNSS rover, locator | Paint, GIS controller |
A survey mark (or survey point) is a physical monument such as a brass disc, pin or nail whose coordinates are known. Surveyors' metal detectors are used to find buried iron pins at property corners.
How does surveying work in the field?
Field surveying follows the same sequence on almost every job: control first, detail second, checks throughout. Each step uses specific surveying tools and equipment.
- Research existing plans, survey maps and control mark records.
- Establish control with GNSS static or RTK observations and total station traverses.
- Measure detail – features, levels and boundaries – with a GNSS rover or total station.
- Check by re-measuring known points and closing traverses or level loops.
- Process the data into coordinates, drawings and survey maps in the office.
- Set out or report – stake design points, or deliver the plan and report.
Surveying units of measurement are normally metres, with angles in degrees or gon; some countries still use feet, including the US survey foot on older records.
Digital measuring devices and laser survey equipment
Most distance and height measurement in surveying is now digital or laser based. The difference between the tools is range, precision and whether the result is tied to coordinates.
- Handheld laser distance meters measure tens of metres to a wall or object with millimetre resolution, but they record no coordinates and are not survey instruments in the strict sense.
- Rotating laser levels sweep a level or graded plane across a site for excavation, slab and ceiling work.
- Reflectorless total stations use a visible or infrared laser to measure points without a prism, which is useful on facades and unsafe areas.
- 3D laser scanners capture whole scenes as point clouds and are the main tool for 3D site surveying.
When choosing electronic measuring tools, check the stated accuracy at the distances you actually work at, not only the maximum range.
New, second-hand or rental survey equipment?
Second-hand surveying equipment and rentals both lower the entry cost, but each has trade-offs. Weigh price against calibration, support and battery life.
- New – full warranty, current firmware and constellation support, known calibration.
- Second-hand – cheaper, but older GNSS receivers may not track all current signals, and spare parts can be hard to find. Ask for a recent calibration certificate.
- Rental – ideal for occasional scanners or robotic instruments, expensive for daily tools.

Frequently asked questions
What tools do surveyors use?
Surveyors mainly use GNSS RTK receivers, total stations, levels and, increasingly, 3D laser scanners. These are supported by tripods, tribrachs, prisms, survey poles, data collectors, measuring tapes, hammers, nails, marking paint and metal detectors for finding buried marks. The exact mix depends on whether the work is topographic, boundary, construction or as-built surveying.
What is the most important surveying instrument?
There is no single most important instrument, but the total station and the GNSS RTK receiver do most of the work on modern crews. GNSS is fastest in open areas, while a total station works indoors, under trees and where the highest local precision is needed. Many firms own both so each can check the other.
What is a survey rover?
A survey rover is the moving GNSS receiver that a surveyor carries on a pole to measure points. It receives corrections from a base station or a network RTK service and calculates centimetre-level coordinates in real time. The rover is paired with a controller that runs the survey software and stores the measured points.
What is a survey mark?
A survey mark is a physical monument whose position is known, such as a brass disc set in concrete, an iron pin, or a nail in pavement. National geodetic agencies maintain control marks, while surveyors set their own for boundaries and projects. Marks provide the reference from which new measurements and setting-out start.
Is it worth buying second hand survey equipment?
Second hand survey equipment can be worthwhile for simple tools such as levels, tripods and poles. For GNSS receivers and total stations, check age, signal support, calibration records and spare parts availability, because older units may not track current satellite signals or may lack software updates. Factor in calibration and battery replacement when comparing prices.
What equipment is used in construction surveying?
Construction surveying uses total stations for precise setting out, GNSS RTK rovers for site grading and earthworks, automatic or laser levels for heights, and stakes, nails and paint for marking. Scanners are used for as-built checks. Crews also need tripods, prisms and poles that are in good adjustment, because setting-out errors become construction errors.
