This format supports Wintec .tec files, such as appear on the Wintec WBT-202™ data logger.
The WinTec WBT-202 stores tracks and waypoints on an internal MICRO-SD Memory card. The log files can be accessed by connecting to an USB host and setting the device into a mass storage device (MSD) mode. To enter this mode, attach it to the computer, then hold the power button until the GPS and Bluetooth LEDs go out. It will then behave like an USB Memory stick. and individual files containing your tracks will show up on the "disk" with names ending in .tes. You can use GPSBabel to read these files directly or copy them to your host computer.
Note that this format is for the TES files on the GPS, it has no relationship to the .TK2 files created by Wintec's Time Machine software for Windows.
Despite the physical similarity to the Wintec WBT-201™, this is believed to be a rather different product. While this GPS probably works fine for realtime tracking over the bluetooth or serial lines (once you have appropriate serial drivers), it's expected to not work with GPSBabel's GPSBabel WBT Protocol module.
