Awesome break down, thanks for the info

[Cauhauna]

I'd like to suggest that "Coverage Area" is a misnomer when refering to LJ's.
There are two factors that come into play during a laser encounter: Detection and Jamming.
Detection is a matter of whether the laser beam's "spot" happens to shine on the sensor in the jammer head. If it doesn't hit the sensor, the jammer won't turn on. Period.
The size of the spot is a function of beam divergence angle and the distance from the gun to your car. The size of the vehicle and the placement of the heads will determine whether the spot will hit a sensor or not.

Jamming is a function of the strength and type (pulse rate and duty cycle) of signal emitted from the jammer, and the ability of the lens to properly focus the beam so that it will hit the laser source. This is tricky--the shooter can point the laser gun anywhere he wants, but the jammer has to cover an area large enough to "paint" every possible location where the gun could be.

The HP heads have only one receiver in them, just like the regular heads, so detection will be the same. However, with two transmitters with 90* polarity, it will send out a heck of a lot stronger jamming signal when it does turn on.

If you have larger vehicle, with places to mount more that 2 heads, 4 regular heads will give way better detection that 2 HP heads, thus giving you better coverage.

Good info as usual from Swamp.

This sounds so logical as to be indisputable, but it brings up another question:

Is there any way for the CPU to know that all four heads are up front? If so, can the CPU synchronize the four head's response, regarding the pulse frequency and timing?

All four Sensors fire simultaneously upon detection irregardless of their mounting positions.

With all CPU versions or is this something new? I don't think I have ever tested this theory personally

[Laser-InterceptorUSA]

All CPU Versions. Give it a try!

Define coverage? Are you saying like the old 18" rule that was used with the older Blinder units?

Sorry I forgot I posted this. This is what I'm talking about however.

Go big or go home.

Buy the HP.

looks like I'll be going home

I have the HP series quad, and so far no hit. Here LEO LEO.....

That's because they always use quick trigger!
