This RedLine radar detector from Escort is considered to be one of the most sophisticated radar dectectors on the market today. What makes it so great is that it’s capable of cloaking itself from all police radar detector dectectors (I hope that’s right) and it warns you of speed traps from over 13 miles away (giving you plenty of time to slow down before the cops nab you).

The ESCORT RedLine is the most advanced radar, laser and safety detector ever designed by ESCORT. The ESCORT RedLine includes full X, K, SuperWide Ka, and Safety Warning System radar capability, front and rear laser detection, dual antennae with varactor-tuned (VTO) microwave receiver, digital signal processing (DSP) for superior range and reduced false alarms, our patented Mute and AutoMute, audible and visual band alerts, and all the performance you’d expect from ESCORT.

The RedLine from Escort costs around $500
