This is a pre-owned item that is in good working condition. This item was tested before listing. The screen has a small blue discoloration in the middle and a couple of black spots but this does not impair its functioning in any way. Please see pictures for more details. (What you see in the pictures is what you get)

Construction Five contains a full set of COGO functions including angle and compass adjustments, rotations, transformations, setting point stakes, staking complex road projects, computing volumes and storing cut sheets—just to name a few. Nearly 100 functions are accessible directly from the keyboard while others appear as submenus of the first list. This review will touch on a few of them.

Data Collection
One of the major functions of a data collector is to obtain topographic information including attribute data. The SMI note field can hold up to 255 characters that can be split into two parts called the note field and the code field. These fields default to 30 and 16 characters, respectively, when converting raw data to coordinates. There is an option to change these values when downloading data, but if it is necessary to edit the raw data and regenerate coordinates, the default values are always used. The requirements of the software used to process this data are the determining factors in how this data should be entered. If more attributes are needed, any programmer can access the ASCII-based raw data file and parse the description field to translate the data into the desired format.
