Detection

Your Detector

Instant-On Detection

Your detector is designed to detect Instant-Onspeed monitoring signals, which can suddenly appear at full strength.

NOTE

You should take appropriate action immediately whenever an instant-on alert is given.

Pop Detection

Your detector is designed to detect single pulse mode radars. These radars are designed to have a low probability of detection. You should note that these radar guns have a much shorter range while in this mode.
