kangaroo/wildlife warning whistles on car

thanks Rob J,
are you sure the bull bar wasn't to protect you from leprechauns
cheers for info,
Anton

Boobook - that reply should be in Friday funnies

440 percent, different...

But 440% true.

Booboo for Federal Treasurer,....... Yaaay!

It's a simple question .... which would you prefer to save you form Roo strike ?

This



or this?

Both + $5,~ whistle as well

Free to waste your 10 bucks....

Behavioural observations of eastern grey kangaroos and red kangaroos in captivity showed that vigilance response did not differ significantly between Shu Roo on and off for either kangaroo species and they did not take flight in response to the Shu Roo. A survey conducted by phone enlisted 17 companies that participated in the road survey from four states, New South Wales, Queensland, Victoria and Western Australia. All participants traveled large distances. There were 58 treatment vehicles fitted with a Shu Roo and 40 control vehicles without the Shu Roo. Collision records showed that very few vehicles hit kangaroos and there was no difference in the number of kangaroos hit by vehicles fitted with or without a Shu Roo.

Conclusion
The promotional literature proclaiming the scientifically proven efficacy of this ultrasonic deterrence device, the Shu Roo, grossly exaggerates its capabilities. The results of the signal characteristics and behavioural responses generate four clear conclusions:
• The Shu Roo is not purely ultrasonic.
• The Shu Roo does not produce sound that is detectable at 400 m.
• The Shu Roo does not alter the behaviour of either eastern grey kangaroos or red kangaroos.
• The Shu Roo makes no difference to the number of kangaroos hit when fitted to vehicles.

ShooRoo is different product. I know it more than any body in this forum, I use to make the product from scratch about 25 years ago! Frankly to say I personally didn't believe in the product very much than as same as today.
I'm talking about the whistles, two small and the other two - bigger made in USA, and combine two of those worked for us.

Danna,

Similar research on Deer Whistles in the US.... look I'm not saying don't buy one if it makes you feel better, however the research clearly states the claims of effectiveness just don't stack up.

http://www.usroads.com/journals/rmj/9705/rm970503.htm

While manufacturers contend deer can hear the whistle up to a quarter mile away, no published research verifies the device's effectiveness. The Insurance Institute for Highway Safety presented evidence refuting claims promoting the whistles:

Georgia's Game and Fish Department, for example, found that in hundreds of observations from vehicles equipped with deer whistles, deer didn't respond. Whistles on vehicles going 25-30 mph produced no ultrasonic sound, although some ultrasonic and lower frequencies were produced when the whistles were blown by mouth. According to wildlife biologists at the University of Georgia, neither deer nor humans can hear ultrasonic sound. Whistles blown by mouth near captive deer produce no response.

A University of Wisconsin study found that three types of whistle did produce low-pitched and ultrasonic sounds at speeds of 30 to 70 miles per hour; however, researchers were unable to verify that deer responded to the sounds, even at distances well below the distances from which manufacturers claim the whistles are heard. Moreover, deer would only be able to hear the whistles if there were a straight shot between the deer and the whistle. If curves, trees, or other obstacles came between the deer and the whistle, the device would be ineffective.

According to an article called "Blowing the Whistle on Deer Scare Devices" in the Mid-February 1993 Farm Journal, the Ohio State Police installed deer whistles on their patrol vehicles; however, they reported finding no significant decrease in collisions between patrol cars and deer. The same article indicated that a panel of the World Society for the Protection of Animals could find no data proving "that such a device can actually stop an animal crossing the road, which is the main purpose of the device." Finally, Washington State University researcher Leonard Askham felt the evidence tended to favor a conclusion that deer whistles do not work. "Even if the devices were effective," Askham warned, "they would soon become clogged with insects and dirt and stop working."

I don't think that the ones hit were necessarily deaf but possibly just confused

They don't understand why we whistle to make a dog come to us and then whistle to make a Roo go away

Remember Sonny used to whistle skip with a gum leaf

Iza, some people would argue that Red underpants don't work because there is a small joey in the pouch.

I thought they only worked when you have a Hyclone fitted.

I've been putting these on the bulbar for a few years.

They don't cost much but I believe they do alert roos that are feeding on the side of the road.
I've seen other animals and birds show signs of hearing something too.

The only roos I've hit have been ones that have belting out of the bush and I would have hit them no matter what.

Try them. They are cheap and won't damage your vehicle.

Steve (another one)

But you never tried them so, you assume .....

There are some gullible people out there Danna ( maybe you are one )

Cheers

You don't have to believe it. But you do not insult others!
I just pointed out that this thread is about physically having devices and if they work or not!
HooRoo Dana

Yep fair enough
apology given .

hooroo

Those Roos probably hadn't paid attention during the mine induction

Yep maybe a hard hat & safety glasses might have helped. At least they don't suffer because there's not such thing as a minor injury when 400 ton pounds them into the ground.

as the guy with the haul truck said - noise has little to do with kangaroos

growing up in the country roo shooting was a major past time
alot of the vehicles we used had straight through exausts
the noise of the vehicle made no noticible difference on the roos.

one thing that did however was a very loud horn

if you were racing a roo to cut it off from a fencline or bush line laying on the horn could often make them double back into the padock

this is why i tell people only honk your horn at an animal you want to hit

Whistling works on roos. We used to whistle to make them stand up and look in our direction when roo-shooting.

The best roo-avoidance technique I have found, when a roo is standing on the road, is to aim at them.
You can be sure the roo won't be on that spot when you reach it, because they will most certainly jump off in some direction.

Roos on the move will generally keep going in that direction about 75% of the time. It's the 25% that fool you, as they change direction and hop straight into your vehicle.

What doesn't work is trying to figure out the direction the roo will go - because they never think about that, they just hop off in any direction - and that can be the exact same direction you didn't expect them to go.

In other words, a roo facing or hopping East will immediately reverse direction with no reason, and start going West - just as you figured it was going East.

Shoo-roo's and other devices only attract animals attention by the noise they make.
They don't make them specifically avoid your vehicle, they just startle them into some kind of reaction.

Most vehicles make a lot of noise travelling at hwy speeds, but if the wind is blowing strongly from the animal towards you, then there's a chance they won't hear you until you're relatively close, and they then get startled.
Then there's the animals that have to have a think about what to do when they're surprised. After a little think, they decide the time is right to hop in front of your vehicle.

Best tip: If you spot a roo or other animal, back off the loud pedal, keep your foot on the brake pedal, and be prepared to pull up sharply in a straight line if a big animal collision appears highly likely.
Don't swerve around animals at high speed unless you want to end up rolling your vehicle over.

Are suggesting they may have an expiry date?

Bugga me, never thought to check the use by date :).

You could be on to something there Munji. Guess I'll have to invest another $4 (+ inflation) and conduct another non-scientific test.

Allan

Somebody did a thesis? Science is a wonderful thing.

You obviously are well resourced. Can you find me a thesis on the Hiclone fuel thingy?

Cheers

Allan - Oh, man! What a market opening you've made for me!!

Roll up, ladies and gennelman!! Get your roo-repelling, "kangaroo foot thump" audio CD's right here!!
Only $99.95! - and we'll throw in a set of free steak knives as well!!

Turn up your ghetto blaster or your 300W car sound system, and just watch those roos flee!!

Save thousands in crash repair costs in the first month alone!! LOL

Cheers, Ron.

Hey Rocco, You wanted a Hiclone thesis?

Here you go.....................

Allan

I knew you could do it!

Cheers

Pop - Yep, driving into pitch blackness at 110kmh will work, for sure!

You just won't even see what you hit! LOL

I can remember the old HQ Holdens had a multiple-bayonet firewall connector in the main wiring harness.
One half of the connector was on the engine side of the firewall and the other half was on the cabin side.
The halves were held together by a large single central bolt.

The connector was supposed to be fully sealed - but the sealant missed a full seal, on more than one HQ build.
If you were working in flood conditions, water and dirt would enter the connector and corrode the bayonets.

Of course, both high and low beam were amongst the bayonet connectors, and if either of these bayonets corroded, look out!

I can vividly recall hammering along a country hwy late at night, at warp speed, and having a car come the other way.
I dipped my lights, the other car zoomed past, and I kicked the dipswitch back onto high beam - and Holy Moly!! Everything went black!!

I can tell you this much - nothing gets the adrenalin pumping like barrelling into sudden pitch blackness at warp speed with no lights!!

I hung on the anchors and kicked the dipswitch again in desperation, and low beam came back on, much to my relief!

A little experimentation found that high beam had stopped working, as it wouldn't come on when the dipswitch was kicked, so I drove home (very cautiously) on low beam.

Next, some multimeter work found the power wasn't getting through the firewall connector, so it was pulled apart - only to find some badly corroded bayonet connectors - with high beam connector the worst affected!

Some cleanup with a little weak acid treatment soon fixed the problem - but I was always wary of those HQ's from then on!

The later Holdens (from the HJ or HX from memory) dispensed with the connector and the wiring was one-piece all the way through, thus eliminating the problem.

Cheers, Ron.

Crusier - With my style of luck, I'd forget to turn it off - and a recorded gun shot would go off, just as a traffic patrolman pulled me up and stepped out of his car!! The end result doesn't bear thinking about!! [:-(

Hi,
no offense, but have you ever tried them?, if not, how can you tell ??
We didn’t believe it either, but now we have seen how they worked and for no more than $20,~ ….. we happy with purchase.
Hooroo

Yes Tuco, If Ms Bender could perform scientific tests to validate her thesis (see my Reply above) that the makers and promoters of these products would do similar tests to support their marketing.

Danna, no offense, but how can you prove they do work??? How have you seen this?

... you forgot ol' man emu ... LOL

Have a nice day.

American whistles?? So that's the secret?? I didn't even know that they had Kangaroos in the U.S.!!
Or is it just the loudness, or the accent in the whistle, that drives everything away?? [;-)

Yes, American, they are made for deer, doe and other large animals.
Ours worked even on roos.
You don't have to believe it. People didn't believed that planet Earth is round either.
HooRoo Dana

Oh, deer! Look at this wiki page for opinions on whether deer horns work!

Deer horns

Like taking a placebo for a medical problem. If you believe it will work it will.

Not everyone will subscribe to that theory though.

Wikipedia says they dont work Thats good enough for me ROFLMAO

They must work though as I had a set for two years and never hit a roo. But then they fell off and for the next two years I never hit a roo either.

So on that theory they work at least 50% of the time LOL

I was under the impression the Firepower bloke did pretty well out of his scam. He's reputed to have socked away at least $38M and he doesn't have to pay anything back, and he isn't going to be charged with anything. That's what anybody would call a winner, in all the shonky deals that have surfaced in recent decades. [:-)

Bazooka, you forgot the static electricity discharge and the sonic mozzie deterrent .... include those and I'd buy one......

But wait, there's more......

Make it portable and add a sonic snake repeller and I'm in Scott.

But Bazooka, snakes don't hear....... they feel ground vibrations.
So you will need the optional foot-thumper attachment.

It's Sunday morning Allan. Snake vibrator just didn't seem appropriate.
