Laser detection is useless.

You need a laser "shifter".

Exactly what I had in mind, but not for Porsche. Also found these, was wondering if anyone has used these?

sounds like you had a similar experience to my weekend. The suction cup gave out and that brick (V1) lands on the dash and leaves a tiny mark.

I pulled out the suction cup mount from an old Magellan GPS mount. I took the suction cup mounting tray noticed it was about the same width as the GPS mount. I grabbed some double sided stick tape and it worked fine. But some proper drilling and hardware is in order.

Something that heavy needs a more robust anchoring.

It is pretty popular to mount to the upper left of the mirror and then pull power off of the mirror. Here is the link I followed: LINK

This worked super for me. If, on very rare occasions (usually while washing the inside of the window) the suction cups give way, the cord catches the unit.
PS: I really would suggest the suction cups from Michaels Craft again. They are thicker and stick a lot more than the stock Valentine.

Why don't people just use the visor clip to mount RDs?

Because when your wife puts the visor down the detector falls down and hits her in the head

Keep in mind that laser is generally THOUGHT to be a tight beam but over range and with inclement weather, laser can scatter considerably. Although an extreme example, a laser pointed at the moon will wind up casting a beam 5 miles wide on its surface. Do some math to determine what error you will see (1º beam error will produce an error of 1 foot in elevation at 60 feet in range). Now, how high is your windshield?

at optimum operating range - a Lidar has a beam spread of just 18 inches

mount low if you want to detect a laser strike

This from a trained highway patrol officer:

At 1000 feet, a radar beam shot from a police radar gun is approximately 85 feet wide. This radar beam can normally penetrate glass, plastic, cardboard and even your body. What radar has a problem penetrating are metals, including some window tints that have meatlized layers.

Laser is a light beam and is only 18" wide at 500 feet. Because the beam is so narrow, and because it's light, the beam can be effected by virtually anything you put between the laser gun and the detector.

Don't mount it high!

During the testing of the products reviewed on RadarBusters by Radar Roy and Speed Measurement Laboratories, the radar detector is always mounted in the manner the manufacture recommends in their manual, in the center of the windshield.

However you will see on this page, that mounting it in this manner will not allow it to receive laser alerts. A laser beam shot at 500 feet is only 18" wide when it hits your vehicle. Police target either the front license plate or the headlamps. If the radar detector is mounted in the center of the windshield, it will be too high to receive any of the "splatter" that may indicate you are being targeted by a police laser gun.

Real world experience from an Ex speed cop who's taken the trouble to review actual unit field tests.
I read the link - and trust the source - but not sure I agree with everything. For Laser, I would tend to agree - but laser with a V1 is hit or miss (pun intended). Last ticket I got was with Laser and the V1 informed me ahead of time that i would be getting a ticket - mounted high, just at the edge of the tint on my '02 C2. The next week, I installed a Blinder system below the front bumper.

Regarding high up -
1) Probably better detection coming over a hill (which is very common in my experience).
2) Much less noticeable when left in vehicle (I never take mine out).
3) Out of sight while driving.
4) I can still reach up and quickly unplug and remove the V1 if I think I'm going to get pulled over. Legal, but better not to "taunt" officers with detectors.

Low mounting -
1) Sun beats down and cooks the unit
2) Easy to spot when parked
3) Less "line of sight" for radar coming over hills

Just my $0.02 - not an expert.
