Black Box Data Logger for Zt-2 and Zt-3 Wideband Systems
The Zeitronix Black Box Data Logger is a flash memory data logger for use with Zeitronix Zt-2 or Zt-3 Wideband systems. The Black Box Data Logger stores 100s of hours of logs using 1GB or 2GB Micro SD cards. Power and data supplied by a Zt-2 or Zt-3 Wideband controller via a 5 foot long plug and play cable. The large button makes activation easy even when wearing racing, motorcycle or ATV gloves. The auto-save feature maintains data even in the event of a power loss. With many non-standard cards on the market we strongly recommend purchasing with the optional 1 GB micro SD card. Made in the USA.
