In the case of surveying equipment, it is very frequent to make a comparison between one model and another, be it from the same brand or from the competition. Each company includes a detail of its products, but making comparison tables is a complicated task.
On this, the magazine Point of Beginning, specialized in the area of geo-engineering and whose Digital version is free, has done a great job for over 5 years. You just have to select the equipment, which can be models from the same or different manufacturer, and after pressing the "compare" button, a comparative table of the characteristics of what we have selected is displayed.
This magazine in each edition contains reviews of different teams, and for each year an update is released that includes the new models. For that matter, this is the review for 2009 that includes 11 manufacturers and 60 different models of Total Station, which I summarize in the following table:
Series SET X
|Leica Geosystems Inc.||TPS1200 + Professional Series
|Topcon||GPT 9000 Series
GTS 230W Series
CTS 3000 series
GTS 100N series

|Suzhou FOIF Co., Ltd,||OTS6800
OTS702 / 703 / 705
RTS702 / 703 / 705
I think it's an excellent job, Points of Beginning Here you can see the table, although it is not the only type of comparisons they have. I also recommend that you Subscribe to the magazine, whose specialty is geo-engineering (it has existed since 1975). Printed only exists in the United States, it is free for companies in the field, internationally there is the Digital version, and of course, it's free.
Unfortunately in the year 2010 the page that developed the comparison stopped operating.
