This is a police model radar gun which runs on 12 volts. Measures targets well and comes with a rechargeable 12v battery pack which lasts for a long time on a charge. Very accurate. I set lots of fields with it before I got a self contained unit. This gun was over $800 new. Comes with calibration tuning fork and Case.
$250 shipped to you.
