Digital Theodolites are great but Total Stations are much better. The
accuracy and versatility of a Total Station can increase efficiency and
accuracy simultaneously. If you need the ability to record X, Y, and Z
coordinates, record height of instrument and height of rod, as well as
distance for a true sense of what you are recording, then a Total
Station is what you need. Total Stations fulfill the need for
applications like land surveying, general construction layout,
construction stake-out, mapping, utility mapping, GIS applications,
archaeology mapping, law enforcement accident reconstruction, and
environmental studies. Generally speaking, Total Stations rest on a
sturdy tripod and are used to record XYZ point data such as your North,
East, and Elevation with the end result of data being a "point file"
which is nothing more than a text file that can be transferred into a
CAD system to begin mapping while connecting the dots. The point data
will have X and Y (which is North and East) as well as elevation. When
buying a Total Station, the accuracy is based on a number of things such
as the optics but the most important specification is the seconds at
which it can measure down to. For example, a 2" (two second) instrument
is more accurate than a 5" (five second) instrument since it will
measure down to 2 seconds instead of 5 seconds. Surveyors generally
require a 2" instrument whereas residential and commercial contractors
can be totally fine with a 5-second or 9-second instrument which are
usually used for construction stake out and verification of locations
and elevations. Most contractors generally work within their job site
and can get to a benchmark or reference point while targeting their work
within 100 to 200 feet away, where as land surveyors are usually
sighting distances much farther away, hence the need for greater
accuracy. Also, keep in mind that "Reflectorless" means the Total
Station does not require use of a prism on a prism pole whereas other
Total Stations do require the use of a prism to record a location.
Whether you need a reflectorless or not, this depends on your style of
work. Most Total Stations today are of the reflectorless type. Last but
not least, you'll need a sturdy tripod, a rod of some type, a prism if
you'd rather use a prism for stake-out and location, you can buy these
products separately or try one of our Total Station Starter Kits. And,
don't forget other supplies such as safety vests, stakes and nails, as
well as roll flagging.
We are authorized dealers for various brands of total stations such as; Futtura and GeoMax. If you have questions or need
help selecting a total station, please feel free to contact us. We
