GPS Logger

This device records you track, and you can later download it to the PC for GIS work.

We experimented with Blue Connection to a PC, but the advent of cell phones with good GPS meant that was a better option.

  • 74x43x10 mm
  • 55 g
  • Bluetooth NMEA output
  • MicroSD storage (only 1 GB cards allowed)
  • Turn off, put in a pocket or backpack, and you will have positions all day.

Logger peculiarities:

  • Files have an ASCII #0 in the data fields, and will not read in some software.  Either open and resave in Excel, or use the option ASCII remove #0 on the Edit menu of the   Menu on data manipulation form
  • Only takes a relatively small storage card, which might be hard to find now
  • Good battery life.  Rechange via USB.
  • Have to remove MicroSD card and use a reader to get data to the computer.
  • Speed is heavily filtered (whole km/hr, and when walking you do not even get all the integers).  But you can Navigation, add travel path, to get much more accuracy, and then filter (Edit, Field arithmetic, mean or median filter) if you want.
  • With Windows 7 (and maybe Vista), the operating system may ask you to enter a four-digit security code for Bluetooth connection to PC; for GPS units, if no code is included with your unit,  ?0000? usually works.

I got this in about 2011, to use with a netbook.  It was first on Amazon in 2008, there are current reviews showing it has not changed much.  The V-990 might be an improved version of the V-900.  In addition to the older VisionTac name, the newer ones appear to be Columbus.  Reviews on Amazon are pretty accurate; if you can live with them, it works well.
