The Lidatek Laser Echo LE-30 does one thing and it does it well. It will detect laser guns and give you enough time to check your speed and slow down while it does its counter measures. The LE-30 is completely ineffective against radar guns simply because it does not attempt to scan them. So if you want the best coverage available, it might be a good idea to pair the LE-30 up with a good radar detector like the Escort series or Valentine One.
