[fox in the hole]

I have a M47 but after hearing reviews about LI I plan to get one...I have a subaru forester with sports grill..I plan to place Li in middle grill where its between headlights and above license plate..then I would like to put M47 on bottom perpendicular to fog lights..it would be maybe 2 feet spaced top to bottom...Ive read if other systems are too close it wouldnt be good But i'm gonn place them far apart..i hate to waste the bliner m47 such a sin...would this be ok.same for the back..anyone know..

Legacy Blinders (M27/M47 series,etc.) have NO DEFENSE against some of the modern Lidar guns of today.Secondly,running them together will cause them to interfere w/ each other b/c of reflections coming back causing confusion between the two.

As in - which is the real threat...reflections from themselves or the IR coming from the Officer's lidar gun targeting you ?
You're asking for a citation if you do this.
