Single Head in the Rear?

[skubysnak]

Regarding 1 rear head, yes it's possible for a single LI head to work only if the Leo aims at or within the head. If the shooter targets away from the head, it's instant reading as the LI head can't see the lidar beam. You can't jam what the jammer can't see.
On the 5 series, there shouldn't be an issue with 2 head placement.

I was told that one LI head had more power than two heads of the other competitor brands. So should one be good enough, even though the risk is higher, but by how much?

No, two heads minimum, or the LEO gets a speed reading. Period. End of story.

Just happened to see this. The last test that I attended, one member had a 3-series with 1 functional LI head in the rear and it was installed towards the left taillight I believe. Their was no "instant" lock on the rear of the car. The shooter had to carefully target the right tail lamp towards the end furthest away from the head. A measurement was easier to acquire with the TruSpeed.
So will the Leo get a speed reading before you have time to react? Depends on the situation...

I understand the 5-series may be slightly wider...

Don't believe these talks of "instant reading." From my own personal testing, 1 standard LI head does seem to have better performance than just about every other 2-head Led jammer available. Amazing detection capabilities and jamming performance. Me personally, I'd use 1 head on the rear because rear targetting is not as much of an issue in this area as it is in others. Also, I have the means to ensure the install is as close to perfect as possible.
But if I were you, I'd follow Cliff's advice to be safe.

That's my point; initial rear targeting is minimal. Here in Hawaii, the "usually" target the front, the rear once you past to see if you speed up. If I get hit from the front, I'll stay at the legal speed limit till I'm away.

What do you mean by intalling "close to perfect". If I decide to go with a single head, I'd place it in the center and level out. Is there some trick to centering?

Why was the head placed on one side vice center? You say the shooter had to carefully target away from the head. I'd assume LE would target center of mass....

LOL. There is no trick to centering. But there are other things you need to be aware of. Ensure that the surface your car is parked on for the install is level. Ensure that your level is "calibrated" or level. What I mean by this is that "most people" just simply assume that the bubble levels they are using to level the heads are true. I have a LI
bubble level that is "not" true on all four sides.... basically, the bubble inside the level reads ok for one side, but then when you flip it to another side, it floats to the left or right. It's just a little something I've noticed that many probably have not.

By "close to perfect," I mean vertically level and aligned straight ahead. Many people "eyeball" the head/heads during the install, test the install, record poor results, and then draw conclusions from this. I don't understand it..
Its of no serious concern to me whether the head is 2 inches to the right or left of the center line of the car, so much as it is vertically level and aligned straight ahead. In all honesty, the receiver bubble on the head should probably be located on the centerline of the car if one head were to be used.

Also, as Cliff said above, Hawaii uses a lot of laser. It is probably best to follow his advice for peace of mind. 2 heads in the rear installed correctly will likely result in you never getting a laser ticket from behind.

The head was placed on the side because he originally had two heads installed and one of them failed rather abruptly. When aiming center mass or at the driver's tail lamp, it was JFG all day. Readings were acquired when aiming at the outermost portion of the passenger tail lamp. But keep in mind that we were testing for this and started at that location in an effort not to trigger the jammer.
You are correct in assuming that most Leos would target center of mass. But there are always those crazy Leos, like member "Fritter," who employ unorthodox targeting tactics that only seem to be common in Texas... He commonly sits 100+ feet off the side of the road while preying on helpless motorists.

Rajah all....Thanks so much for being patient with a noob. Totally appreciate all the info...

First Save: Coming down the H2 from Mililani to Pearl Harbor. Not paying attention, I was doing about 75mph+ in a 55mph zone. I got inside 1000' when the alert went off. I see the LE on the side of the road a immediately. A few seconds after passing him, I get hit from the rear; alert goes off again. I continue to drive away with a smile on my face. This all happened at about 8:45pm. I'm good...

Congrats. But you do realize that once you reach a safe speed, you should turn the jammer off so as not to arouse suspicion from the Leo. I understand your eagerness in wanting to test your setup but JTG and JFG can still result in a ticket or tickets. Be careful, drive safe, and enjoy the LI.
