Hello from Maryland! A laser jammer convert.

You will want to get a radar detector first, especially if you are new to the countermeasure game.

Valentine 1, Escort Redline or Max are you highest performing options.

I havent seen any rear lidar shots in MD so you will probably be good with a front setup if. ALPs & LIs will jam the Poliscan speed camera(which is widely used in MD) usually pointed at the rear of your vehicle.
