I just found them at midway and they are called the lite model and are $599. Is the app and Bluetooth worth anything? I think it would be nice, but are there other things to consider before I purchase?Spoke with folks at Labradar 2 weeks ago. New batches are suppose to hit Midway and Scheels in the next few weeks. Some changes to design, no Bluetooth and will be SD card for data transfer only. Price suppose to drop to 539.99 due to electronics changes.
