Shu Roos - Another stupid question!

you should be able to hear a 'ticking' sound.

Hi there Mr Walker!! There was a discussion took place on this forum a while back. Have a look at thread # 47580.
Good luck

Don't wish to over simplify your concern, but have you thought of getting an animal, perhaps a dog or cat, maybe one that annoys the heck out you, sitting it in front of your vehicle and judging by their reaction assessing whether the unit is working or not. A clue, the speed of departure of the said animal may be a good indicator. Not very scientific however.....!! Good luck with it.

Driving through Ivanhoe at 12am and if you know that area, then you would know the roo's are thick as flies up there.
Had the shoo-roo on and roos getting out of way then we hit water, splashed everywhere and next roo kapow and that's at roo speed which is 80km/hr when driving at night.
Hit 2 more and decided shoo-roo was not working.
I now have a pair of those plastic cone shaped shoo-roo thingos which emit a high pitched frequency, which is activated by the air flow and is inaudible to human ears and haven't hit an animal since. Not saying they work, but.........
So, shoo-roo hoo-roo, and only $5.95.

I have a friend who works for a large regional organisation and all their vehicles are fitted with shoo roo's and they are hitting roos all the time.
I also remember watching an old Repco rally, I think, and Ross Dunkerton hits a roo while saying "Shoo roo doesn't work"

Drive around Perth tomorrow and if you dont hit a roo, i'd say it is working.... Sorry i cant be more help LOL!! Michael

they dont work! put 2 on - hit a roo - put another 2 on - hit 2 roos and lost 2 with the impact - If my maths works I should only hit one next time!

I have a shu-roo, depending on your hearing ability you can hear a noise when it is turned on. To me it sounds like a cricket ther adults hear clicks, my kids hear it much clearer than me. Another way i have found is to turn on my AM CB with the squelch down low, or the car radio on an AM station and you hear a cycling sound thru the radio.

My dog always used to walk right up to the device to try and figure out what it is but now she ignores it. Dogs on the street will react to it but pick young ones.

I think the ShuRoos work well if you put them underneath the accelerator to keep the speed down.

An interesting experiment.

Executive summary
Animal/vehicle collisions are a concern in many countries because collisions raise
economic, welfare and conservation issues, which have gained momentum with
evidence that the number of collisions is increasing. Collisions between animals and
vehicles are caused when animals and vehicles occur in the same place at the same
time. The three broad factors that bring animals and vehicles together, creating the
potential for roadway collisions, are the attributes of the road, the behaviour of the
animal and the behaviour of the driver.
Kangaroos are considered a pest species throughout Australia, in part because they
collide with road vehicles. Although human fatalities from kangaroo/vehicle
collisions are rare, it has been estimated that a kangaroo causes a similar amount of
damage to a vehicle as does a deer (A $3000 / vehicle). Eastern grey kangaroos,
western grey kangaroos, red kangaroos, swamp wallabies and red-necked wallabies
are the most commonly hit species throughout most of Australia.
The methods available to reduce the number of animal/vehicle collisions can be
divided into those that 1) minimize vehicle damage, and those that 2) avoid collisions.
One popular method of avoiding collisions is the use of sonic deterrents, such as the
Shu Roo. The Shu Roo is an ultrasonic deterrent device that claims it warns
kangaroos of impending danger, enabling them to flee from the path of the vehicle.
This study tested the efficacy of the Shu Roo. Tests were limited to eastern grey
kangaroos and red kangaroos. Efficacy was measured by systematically testing the
claims made by the manufacturer in a static and dynamic environment. This included
characterizing the Shu Roo signal in the lab and field, measuring captive kangaroo
behavioural response in static trials, and comparing the rate of kangaroo/vehicle
collisions for vehicles fitted and not fitted with a Shu Roo.
Lab tests found the Shu Roo signal was composed of a mix of audible and ultrasonic
frequencies with a short syllable (<0.6 s) that was repeated approximately two times
per second. Static field trials showed that the Shu Roo propagation patterns were
similar on grass and bitumen surfaces, with the Shu Roo signal just detectable at
50 m. Recordings made during dynamic drive by tests of four vehicle types at
different speeds showed the Shu Roo signal was not detectable above the noise
produced by the moving vehicle and therefore there was no difference between the
Shu Roo on and off.
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.

Hmmm.

I haven't got a uni degree, but even I can figure out that:

"Collisions between animals and
vehicles are caused when animals and vehicles occur in the same place at the same
time."
