WA cops can't do anything as they are still legal here.I have mine in the truck in full view, not a problem here YET.There are 2 undetectable radar detectors, the Beltronics XR/STI and the REDLINE from Escort, both cant be detected coz they have magnesium cases.No leakage/no signature. Forget all the rest, even the mighty valintine 1.No point havin it if they know you have it. NOTE; no radar detector can protect you from LASER. It merely informs you that you have been hit. Too late.You need to have either a jammer[ illegal] or a combo of RD/ jammer, still illegal.The RD to inform you ,you are being looked at,and the jammer to hide your speed till you can bring your speed down to where it needs to be.Then turn off the jammer so the good officer can see you are obeying the set speed limit.If they suspect you are doing something dodgy, they will pull you in and search for your stuff. Do yourself a favor,get the L.I. This one does it all,and you can effectively become, invisible.speed cams/fixed cams/laser/HH laser ...the LOT.Its covertly hidden so is not easily found if they look.It has a safety feature that if you ever searched, you can shut it down and defaults to being a parking sensor only.Only LI-usa can make it 'jam' again, a simple phone call...your secret code ectt....bingo, your good again.All this for probably less than $1000 dollars.....thats cheap insurance i think
