TMG GRL-309 is our first stealthy model. In order to make it immune to radar detector detectors, we did a few improvements on our GRL-303. We lowered the power consumption to a half of GRL-303, and turned our unique adaptive threshold mode from a signal control feature to a power management feature. Now the possibility of being detected by a RDD is nearly zero. To learn more about our innovations, please feel free to contact with us.
