Pop Radar Guns
The Pop mode Radar Gun is a single pulse Doppler radar that is a feature
of a K and Ka (Bee III Ka radar gun) band Instant-On radar gun. It uses a single
short time pulse to measure the target vehicle's speed. Despite the fact that
the short, single pulse makes the unit very sensitive to officer hand and vehicle
movement and reduces the range of the gun in Pop mode to 50% of its range in
Continuous Wave mode, this feature is added in an attempt to make the radar gun
invisible to Radar Detectors.
Although your detector can sense Pop signals beyond the effective range of Pop
radar guns, there will be a signal to sense only if a gun is triggered. In addition,
the Pop mode receiver section is more prone to false alerts because of its extra
sensitivity. This is especially so in urban areas. As a result, you should consider
using the Pop Detect mode only in highway and rural situations. Cobra Electronics
has included a user selectable On or Off Pop Detect mode.
