Whistler has two features that make our high end models special!


These features provide a unique Signature ID for Ka band radar and laser transmissions. This feature provides more detailed information about the alert the unit is receiving.
Radar Signature ID - RSID
  RSID Display Example
RSID indicates Ka 33.8, 34.0, 34.3, 34.7 or 35.5 on the display when police radar alerts are detected within these common Ka speed radar windows. Alerts that fall outside of these parameters will be reported only as Ka band.
NOTE: Every Ka alert should be treated with caution.
  
Laser Signature ID - LSID
  LSID Display Example
LSID indicates the Pulses Per Second (PPS) transmitted by Speed Laser or other forms of laser sources. With any false laser signals from some automotive active cruise control systems, for example, the unit allows you to lock out these false alerts based on the pulse rate!
