I'm running a concealed BEL STI Driver since detectors are not legal where I live.
If I were living in an area where undetectability was not an issue I would choose the Valentine 1 for the indicator arrows.
I frequently drive the I-87 corridor late at night with nearly nobody on the road and there are at least 5-6 speed enforcement units operating between the Canadian border and Albany nearly every time.
Here are a few pics of my setup.
As far as laser jammers go check out the guys of lidar website and decide for yourself.
