Why the RD850 is the
world’s finest

These advanced features set this
detector apart from all the others.

• Super Wideband Ka: Gives you complete detection of

the entire Ka bandwidth-33.4 to 36.0 GHz.

mediate Frequency Rejection: Rejects common

•Inter

sources of false alerts caused by intermediate
frequency interference.

• VG-2 Shield

VG-2 (Radar Detector Detector).

•Front and Rear Laser Tracking: gives you optimum

warning time by detecting laser signals from the front
and rear. Also detects off-axis laser signals.

• Laser Detection V
