Beltronics and Escort are now the same company/ownership I believe, and both the X50 and the X65 have auto 'filtering' capabilities. The escort website states:
The Bel states:Exclusive Auto Sensitivity Mode
Intelligent AutoSensitivity™ mode provides maximum radar detection range, while virtually eliminating annoying false alarms from motion sensors, automatic door openers, etc. Highway and City settings are also provided.
I have no idea how the detector can differentiate between a motion senser and a real police threat since they are on the same frequencies or so, but has anyone tested the two modes to see if they actually are the same or more so, filter ANYTHING, I have noticed on my X65 when I put AutoScan it makes K and Ka waaay more sensitive, the slightest thing will set off maybe an alert to K4/K5 when normally in highway it would be K1/K2 etc.New AutoScan™ mode
virtually eliminates false alarms
