I would disagree about the detector. Maybe in Cali or heavily populated areas, but in smaller-medium sized cities and most definitely rural areas they are nice and do work well if you will spend the money to get a nice one ($400-500.) It's not a for sure thing but they do a decent job at detecting a good ways out.
