Wintec WBT-202 GPS Data Logger in Field Test

In the practical test, the GPS logger with u-blox 5 chipset and data storage on microSD card must show what he really can.

The Wintec GPS logger in the field test

Good GPS loggers are especially important for track-based geotagging. Wintec offers with the WBT-202 a Geologger with the u-blox 5 chipset and a data storage on microSD card. The one ensures high precision, the other for long recording time.

In the review with test, the WBT-202 must show whether it really is a “super-logger” and how practical the functions for geotagging and outdoor are.

First impression

The Geologger is nice and small with 57 grams. For the bottom is a rubber for sticking itself.

Soft paint dissolves

Soft paint dissolves

The side gripping surfaces are rubberized and give the device pleasant tactile properties. The surface feels soft velvety thanks to soft paint. Unfortunately, this varnish dissolves with me after numerous stays in various pockets in places.

Of course, great is the microSD card under the battery. Up to 2 GB cards fit in. That means about 134 million waypoints. Which equates to more than four years of continuous recording with 1 waypoint per second.

Battery life

Replaceable battery

Replaceable battery

For the power supply, Wintec relies on a replaceable Li-ion battery (compatible with Nokia BL-5C ) with 1200 mAh. The achievable durations are sensational. No test charge was empty under 24 hours. I reached a record of just under 30 hours with a single charge.


Two buttons, three LEDs

Two buttons, three LEDs

With only two buttons, the operation of the Geotaggers is quite simple.

The logger is switched on and off by the left power button (about 3 seconds).

The left permanently lit LED indicates searching for a GPS position. If the current position is found, the left LED flashes.

The middle, blue LED indicates the readiness for the Bluetooth connection. If the logger stores data, the middle LED flashes orange.

With the right button, waypoints are set by short pressure. With a longer pressure (until the green glowing left LED goes off), a new log file is started.

Computer connection and software

Mini-USB port

Mini-USB port

The Wintec Logger has a Mass Storage Device (MSD) mode. This means that he behaves on the computer like a USB stick.

To enter the MSD mode connect the activated logger to the computer and then press the power button for 3 seconds. Now the middle LED flashes orange and shows traffic.

You can now access the memory card from Explorer or Finder. The main directory is WBT_Tool.exe. This Windows program is needed for logger settings and the conversion of the tracks.

When launching the WBT tool, the last recorded track is displayed in a browser window on Google Maps maps. The actual program must first be fetched from the taskbar.

Important NOTE:
Google has recently made changes to the Maps application, so the map view will no longer work on older WBT Tool versions. Simply download the latest Win-Tool (V 5.0) from the website and copy it to the memory card.

TimeMachineX is still available for download from Wintec in version 2.7.1. This software makes it possible to read the data from the GPS logger, to make adjustments and to provide images with geotags. Since the program in connection with the storage on SD card is not really needed, I will not go into it.

Record track and prepare for geotagging

To record the track for geotagging, there is nothing to do but turn on the logger. Once there is a GPS fix, the recording starts.

At home, hang the logger in MSD mode on the PC and start the WBT tool.

LOG data transfer

LOG data transfer

On the second tab “LOG Data Transfer” the desired logfile can be selected based on the date and best converted into the universal GPX format. A right click in the bottom field opens the “Copy to …” command to transfer to your own computer.

Another option is to simply copy all TES files directly from the logger (from the “WBT202” folder) to the computer and use them with alternative software.

Alternative software

Even if the normal Windows Explorer and the WBT tool is enough to get to the tracks, there are plenty of useful alternative software. Especially for users of Mac and Linux computers.

  • For the Mac, the recommendation goes clearly to myTracks for Mac . This program is more than just a tool to read the memory. Track management and geotagging of photos are also included.
    → My review
  • Read tracks and in standard formats also works with HoudaGPS on the Mac. → My review
  • GPSBabel can also convert the TES files to standard GPS formats. Works on Windows, Mac and Linux systems. → My review
  • GeoSetter can import the TES files directly for track-based geotagging.
    → Geotagging Howto
  • There is an app for Android – TES Convertor . Unfortunately, this did not work in my tests. After a request with the developer this wants to look at the problem and fix.

Practical tips and settings

The huge memory eliminates the need to create sophisticated rules for recording the tracks. The easiest way is to set the recording interval to one waypoint per second.

But beware! There lurks a trap. Despite the active time interval, the speed range is still active. And here is the maximum speed 100 (km / h). During a ride on the highway, it happened to me that only the piece was recorded on a cross. For the rest of the route I was faster than 100 km / h on the way. When changing the LOG settings, set a high value here (maximum 2000 km / h).

Optimize LOG mode

Optimize LOG mode

Another trap lurks at the motion sensor. If the logger is not moved for a defined time, it automatically switches to standby mode. This can prevent unsightly “waypoint heaps” and increase the battery life even further. But the sensitivity is not very high and can not be adjusted. In your pocket when hiking or mountain biking, there should be no problems. When driving on a good road, it has already happened to me that the logger has switched off. Better turn off the motion sensor in the WBT_Tool right away.

Personal conclusion

WBT-202 with memory card

WBT-202 with memory card

The perfect geologist, the WBT 202 comes very close. He is small and light. At the same time, the battery life is enormous. The GPS reception qualities are top. By storing the tracks on the microSD card there is almost infinite memory available, which can easily be read out via the MSD mode.

Unfortunately, it is not stored in a standard GPS format (GPX or NMEA), which requires a conversion. The price is borderline. For a few euros more, there are already outdoor navigation devices with color display and map display for a much wider range of applications.

I like that:
  • Huge memory
  • Long battery life
  • Small
  • Light
I do not really like it that much:
  • Expensive
  • No standard GPS format
