Theodolite with Distance Measure:
      Theodolite with Electronic Distance Measure

The geo-FENNEL TheoDist is equipped with a variety of programs from simple distance and angle measurement up to precise three-dimensional setting out:


Missing Line



Remote elevation measurement


Integrated application programmes for setting out office generated designs
Supplied with: Charger, 2 rechargeable batteries, USB-Cable, Software, Hdmini Prism Set, Case.
The geo-FENNEL TheoDist is a new instrument designed to be easy to use and quick to set up on any construction site. Inexperienced users and professionals alike will benefit from the menu driven software with its intuitive structure and function keys improving productivity and saving valuable time.
The principle features of the geo-FENNEL TheoDist:
Measuring programmes that provide efficient and easy solutions for setting out
Reflectorless measurement makes inaccessible target positioning a thing of the past
Three-dimensional measurement of coordinates
Menu driven software with intuitive structure to maximise productivity
A visible laser pointer to improve targeting accuracy and allowing measurements to be taken without looking through the telescope
Data can be uploaded and downloaded to a PC via the RS232 connection
Quick and easy set-up with the integrated Laser Plummet
Measuring range of up to 200 m without a reflector and 600 m with a single prism
Affordable price
The communication software supplied with the geo-FENNEL TheoDist allows the user to save the data in various formats. The data files can be converted into DXF format making them suitable to be uploaded into CAD Software such as AutoCAD.

A visible laser pointer to improve targeting accuracy also allows measurements to be taken without looking though the telescope.
Measurement to a variety of targets including reflectorless measurement with a range up to 200 meters depending on the target quality and position in relation to the instrument.
Can be used with any geodetic prism with a zero constant.
Reflective measuring tape and targets can be used for fixed positions, monitoring and reference points.
The electronic compensation system monitors the system levelling status and eliminates levelling errors.
Supplied with 2 NiMH battery packs with more than enough power for a full days work.
Internal memory for data storage of 50.000 points which can be saved in various data files.
Two keyboards with large easy-to-read displays. Alphanumeric, user defined and function keys.
Integrated laser plummet for quick and easy setting up over a ground point.
Compact and solid design to ensure stability.
  Integrated Application Programs
Measuring and working in a three dimensional coordinate system.
Measure the height to an object by indirect measurement when a direct measurement is inaccessible.
Calculation of the slope distance, horizontal distance and vertical height difference between two measured points
Determines the coordinates of the instrument by measuring multiple known points. The instrument can determine its position from a minimum of two to a maximum of 10 known points.

Calculates the distance and angle
to a point you want to measure by
positioning the target in front,
behind or perpendicular to the
line of sight.
The area can be calculated by measuring
its perimeter with a minimum of three
