    Was coming home today 4 lane road and got a whiff of ka. I always speed on this road about 15-20 over. Couple seconds go by and got another. Then another.

    Kept looking around and noticed a blacked out unmarked suv about 1/4 mile back in traffic. He was sampling oncoming traffic with I/o ka. Next thing I know he pulls a U and goes after someone in oncoming lanes. R3 knew he was there the whole time!

    The R3 is the kind of detector you want in that scenario!

    Be safe !

    The risk of being clocked from behind can be reduced by going much faster—above the speed LEO would be cruising.

    When you get the “whiff” time to slow down

    I've been super impressed at the R3's detection ability in 34.7 from behind. Gives the V1's rear detection a run for it's money.

    Not all moving guns have the same lane same direction capability. If he notices he is not catching up to you he might just sneek in and pace you.

    Not really, no. Tested and verified. Both the V1 and the Max360 have far better rearward visibility. Just because you got a blip from behind doesn’t mean that it’s giving those with rear horns a run for their money. They would’ve been alerting far earlier and harder.

    I have messed around some with same lane testing and it appears to work ok if the road is straight. Curves and dips in the road make reading a speed more difficult.

    I was pulled over by a sheriff who was shooting same lane out his back window. I was traveling behind him and he pulled over off the side of the road and let me pass him and then he pulled me over for doing a whoppin 60mph in a 45 zone. This was one of several times I was lucky and got a warning. Of course my luck eventually ran out. :tinfoil:

    What's fun is when you see them pull over and you know what's coming, and you pull over before you pass them :D.

    I knew what was coming but I was on a two lane country road. I thought about just stopping in the middle of the road.

    Greatly depends on whats nearby for reflection and terrain, if you have a nice big 18 wheeler directly in front of you the R1 can pickup the rear detection pretty well cause you have a nice big flat reflective surface... in the wide open with nothing ahead of you, then I could fully expect the R1 would lag a dual horn design. I had a divided highway where my rear arrow (V940) lost signal first but the R1 got a sniff from a large 18 wheeler making a turn across the oncoming lanes that acted as a really nice reflective surface... not a standard situation, but that R sensitivity when coupled to a nice reflective surface can give some great rear range I was about 2 miles out when that truck made the turn and the R1 got the sniff. for typical driving though a rear facing horn gives better range... 99% of the time my rear facing V940 picks up weak rear threats before the R1...

    I've had a couple of people that have shadowed me in my blind spot 1 lane over.
    After a while, I'll slow down quickly and sometimes they hit the brakes too for no actual reason. It's weird to see. :)

    Monkey see monkey do. Sometimes I’ll swerve around potholes and stuff and the cars behind me will do the same and then I’ll just do it randomly to see and sometimes they’ll copy.

    I probably should have mentioned the dark blue Charger I was driving at the time. :D

    n the road
    It really depends on how much reflectance is available to the RD at the time. If there's big signs ahead (direction of travel), any RD will be able to pick up those reflections with their front horn. If there's little or no reflectance available to the RD like a forest or little to no other vehicles or metal objects then yes, the V1 and Max360 can out gun a standard RD by virtue of their rear horns . In most metro areas, there's more than enough metal and microwave enery being bounced around to give near any RD a good shot at getting the rear shot. I believe its relatively rare to get a rear shot radar ticket and its more likely to be a pace ticket at that point. Point is: At least you KNOW he's there!!

    FWIW, the V1 horn is very good at catching rear shots and you'll at least know he's there with its arrows. Takes the guessing game (where is he??) out of the encounter.

    Of course that helps a front-only detector. But it is not a substitute for a rear facing horn nor even then qualifies as giving rear facing horns a run for their money. Like you said, in my experience at my usual pace, getting tagged by radar from a cop coming up behind me isn’t common, and arrows in general have more utility than just that. But I don’t want to let this myth persist that any detector, even the R-series or RL-o with BS/RDR on Ka, is going to give you the same kind of rear shot sensitivity that a Max360 or V1 will provide with their rear facing horns.

    This is a case where I really like having arrows on the Max 360. However in most situations my R3 does just fine and at a greater distance.
