I have used a snooper s5-r for past 6 years. Picks up laser and radar, has 3 logic modes to help screen out false alarms such as traffic light radar etc. It has picked up laser, but the main use in radar - if the car in front of you gets targetted the scatter is picked up giving you time to adjust speed. It also gives some warning of gatsos and lets you know if they are turned on - lots are not. I have a tom tom satnav which I have the pocketgpsworld database on for static/likely sites etc. Bottom line is none pick up unmarked cars.
