CMI MPH Industries Z25 Handheld Radar Gun


with POP Technology (in original case)


I have for sale this MPH Z25 K-Band Handheld Police Radar Gun with POP technology.  If you are not familiar with POP technology it allowed the operator to send out a very short burst (67ms) to acquire a vehicle speed. It was so fast radar detectors were unable to detect the signal and alert.  Fortunately for speeders,  any speed obtained by POP was not admissible in court, so it never really caught on.  This gun is several years old but has been sitting in storage for many years, not being used. I have been watching Ebay for over 2 years to see one of these come up for sale and I have never seen one.  They are very rare.  Radar Unit and Original case included as shown. No other accessories or instructions included.  This is an MPH unit.  K-Band. Stationary Only. I have tested the unit with tuning forks and it gets accurate speeds.  These guns must be recalibrated and recertified usually every year for law enforcement use to be able to stand up in court.  This gun has been sitting for several years and has no calibration certificates.  Expect that you should need to have the unit checked out and re-calibrated.  I can only guarantee the unit powers on and tests ok with the 35 and 65 hour tuning forks as mentioned.  I will upload a video soon of the unit operating. Any questions please ask!  Thanks!

The Z-25 handheld is the most advanced stationary Doppler radar. The Z-25's POP™ feature allows the officer to monitor traffic speeds all day without setting off a single radar detector. There are two speed displays, allowing both “track-through-lock” and “fastest vehicle” readings. This second display also confirms the radar's status at any time that the operating mode is changed. Activation of a mode key is confirmed by synthesized voice. The Z-25 package includes the radar, carrying case, and removable DC power cord Handle.

Has variable audio and range, internal calibration test, segment test, RF hold and audio squelch.  Low Volt and RFI warning indication.
