I am not sure of which company or brand- But it has a Chrono that uses an infrared that emits from the sensors to read the velocity, lighting will not be factor for a reliable reading, and it runs on battery , so it can be use outdoor/indoor.
The Labradar was unveiled at the 2014 Shotshow and was supposed to be released to the public last spring. This is one I'm very interested in, but they've been putting off the release date for so long I'm getting discouraged.
As of this moment I have a Chrony and a 35P; when set up in tandem, the inconsistency of the Chrony is very apparent. I would trust my 35P for working up loads, but not my Chrony.
