Intuitive radar that learns the driver's habits and eliminates shadowing and combining, making your job easier— The Eagle II monitors the patrol speedometer and directs the DSP to search for patrol speed around this known speed. What makes the Eagle II unique is the SMART Patrol Search feature that makes your speed readings more accurate by eliminating patrol speed combining and shadowing even when the TruTrak feature is not being used. Using the HOLD switch, the operator can correct the unit if an improper patrol speed is detected. This directs the unit to look for patrol speed in another area then narrows the search window. When the unit comes out of HOLD, it finds the patrol speed quickly preventing combined speed readings.
