Simple! - "Don't speed" - I hear echo amongst the narrow minded. That's fine, and we agree whole heartedly, but "Don't speed and you won't have to pay a fine" assumes three very important things:
1) The speed limit is clearly indicated (Kwinana Freeway road works with two different posted speed limits on either side of the road ring a bell?)
2) Your car's speedometer is accurate.
3) The radar, laser or speed camera that measures your speed was accurate.
So what happens when you are driving down the road, sitting on 80km/h (according to your speedometer) in an 80km/h stretch of road, but you cop a speeding fine?
We will analyze each WA speed measuring device and discuss the products available:
The "Falcon" hand held radar gun (made in the USA) operates on K-band. The police officer points the "gun" towards the approaching vehicle and squeezes the trigger. In this "instant on" mode you have little warning if you're the only car on the road. The ideal situation for early warning is if a motorist in front of you is targeted first, and the radar beam travels past his car, it is detected by your radar. Most detectors (cheap included) will detect the K-band radar at long range.
Dash Mounted radar:
The dash mounted Golden Eagle by Kustom Signals is similar to the hand-held radar above, operating on K-band. When the police officer is driving down the road "shooting" at on-coming traffic he is doing it in two ways; "constant on" or "instant on". In constant on, the radar beam is constantly transmitting down the road. When an oncoming car enters the radar's beam, a reflected signal is returned to the gun, and a speed is displayed on the unit. Again, any decent radar detector will give advanced warning in this scenario.
In "instant on" the radar unit is powered on, but not transmitting. When the approaching vehicle is within range, the radar gun is then switched on (transmitting) and the target vehicle's speed is displayed within a second. "Instant on" radar can be deadly, especially, if you're the only car on the road. For this reason it pays to keep a "rabbit" in front of you so he or she is targeted first and you can detect the police radar in advance.
What about a radar jammer?
Some people have queried the possibility of a radar jammer.
Your most important question
in purchasing a so-called radar jammer should be "does it work?"
Hand-held laser (lidar):
Laser guns are another "deadly" device in that they can calculate your speed in less than a second. Although most radar detectors include a laser sensor, they usually offer little more than a "ticket notifier" when they go off. Having said that, there ARE circumstances where a laser (detector) can and has, provided adequate warning...
So what is the best defenses against laser? Well, as far as a detector goes, the best at detecting laser is the Valentine One. Granted we just finished convincing you a detector is useless against laser, but the Valentine One, will give you the best chance of detecting "off-axis" laser from the car in front of you being targeted. For proof that the Valentine is the best unit at detecting laser, you can read Bob's (The Veilguy) Laser Detector test:
We conducted out own laser jammer test and came to the same conclusions.
But as aforementioned, just detecting the laser won't be enough. The most cost effective solution is with the use of Veil anti-laser paint. Veil will give you additional seconds warning time when used in conjunction with a good laser detector. You can read more about Veil in our laser jammers section.
The best defense against laser is by the use of an active laser jammer. Unlike most active radar jammers, active laser jammers do work. An active laser jammer will prevent a speed being displayed for a brief time whilst you adjust your speed if necessary. The best laser jammers for the Australian model LTI Ultralyte according to the Guys Of Lidar 2007 test are the Laser Interceptor and the Blinder. You need to look at the results for the Ultralyte 100pps as these are the laser guns used in Australia. The Laser Pro Park finished fifth in the test against these laser guns.
Multanova Speed Cameras:
The Multanova 6F speed camera operates on Ka-band at 34.3GHz at such a low power level, you require a VERY GOOD detector to achieve any advanced warning, especially when the radar is pointed at the rear of traffic, taking your photo after you have driven past. The best radar detectors for Multanova speed cameras are ones that either through their fixed or user-adjustable programming, can specifically look for the Multanova's 34.3GHz signal of the Multanova. This is referred to as "Ka-narrow band" or "Ka-narrow sweep". Instead of scanning the entire Ka-band of 33.400GHz to 36.000GHz (a range of 2600MHz or 2.6GHz) the detectors with "Ka-narrow" scan a much lower range of around 200MHz.
Think of it like your car's FM radio. If you started at the
very bottom of the FM band range, its about 88FM and the top is something
like 106FM. Let's say you wanted to pick up an intermittent radio station at
This is similar to how the "Ka-narrow" setting works on radar detectors, such as the Bel 990i, the Bel 975r, Bel 966r, Bel (Target) Euro 550, Euro 330 and the Valentine One. Popular radar detectors such as the Bel RX65, Bel STi (Bel XR) and Bel XR950 do not have this "Ka-narrow" programming therefore do not perform as well against the Multanova cameras as those detectors that do. This is why we struggle to see how the so-called "Aus tuned" Beltronics detectors sold in Australia really are tuned for our conditions!
