Does the Pocket Radar work at night?
The Pocket Radar will take a radar measurement of speed at any time you press the big red button, day or night. However, you may have a hard time reading the speed display unless there is enough light to see it. The Pocket Radar doesn’t have a backlight for the LCD display. This was to assure there would be plenty battery life rather than spend the battery power on a backlight. If you didn’t see the speed because it was too dark, bring the Pocket Radar up to a light bright enough to read the display and push the RECALL button. The black RECALL button will bring up the last ten speeds that the Pocket Radar measured, one at a time, every time you press the RECALL button again.
