In the case of surveying equipment, very often appears the need to make a comparison between two models, either from the same brand or from competition. Each company includes a breakdown of their products, but make comparative tables is a difficult task.
On this, the Point of Beginning Magazine; specialized in the geo-engineering area and which digital version is free, has done a great job for over 5 years. Just select the teams, which can be models of the same or different manufacturer, and then pressing the “compare” button shows a table comparing the characteristics of what we have selected.
This magazine in each issue contains reviews of different equipments, and for each year brings an update that includes the new models. For the case, this is the review of the 2009’s year, which includes 11 manufacturers and 60 different models of total station, which I summarize to you 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
GPT 7500 series
|Nikon/Tripod Data Systems||NPL-502 Series
|SOUTH||NTS-960R WINDOWS SERIES
NTS-960L WIN SERIES
|Pentax / Western Latitudes||R-300NX Series
|CST/berger||CST 200 Series
CST 200 Series
|Laser Technology, Inc.||MapStar AE LPS
MapStar CM LPS
TruPulse AE LPS
|Spectra Precision/Tripod Data Systems||Focus 10 Servo & Robotic
|Suzhou FOIF Co., Ltd,||OTS6800
I think it’s an excellent job of Points of Beginning, here you can see the table, although it’s not the only type of comparisons they have. I also recommend subscribing to the magazine, which specialty is geo-engineering (established since 1975). Print version only exists in the United States, it is free to companies in the same industry area, and worldwide digital version exists, and of course, is free.
