yes we use them on our car as well seems to work Helena.

I've just given a detailed account of my opinion, and the reason why, in the Techies' site. I wouldn't be without them.
Cheers,

The ANU research although dated  makes very interesting reading so thank you for drawing attention to it  .

I understand from the device literature that to generate sound from the device  a speed of  no less than 80kph  is necessary, hence  with the device having an effective range  of 50mts, vehicle at 80 kph  and a kanga in full flight traveling at right angles to the oncoming vehicle +van   it must be concluded  that  impact with  the  kanga at point X  whilst at terminal velocity is inevitable .  End result Kangas Nil  - Vehicle 1

 

Ha Ha........well put Wombat. Maybe I will still put them on (the cheap plastic ones) to at least FEEL I am giving the Roos and myself a chance of avoiding a collison even if they don't work!

If my rough calculations are right then from time if sighting the kanga at point "A" to impact at point "B" is around 3.7 seconds even with the reaction times of a fighter pilot good luck in avoiding the big bang. I have them on my vehicle so obviously I haven't taken all the research into account either.

The ides as G/Ns is too travel comfortably, dont drive in the at dusk or early morn, if you have too drive slow and alert, Had one when they firsy came out about 10 years ago, didnt work then , and mates tell me they dont work now,

I have a #1 golfing Iron strapped to my bull bar. Works for everthing, as even the almighty cannot hit one of these!

the shoo roos work very well but are too costly for me, I use the cheap plastic whistley ones and will attest here and now that they do indeed work very well at speeds greater than 40 km's per hour I dont know about this point "a" and point "b" and terminal velocity I do know that when I see a roo sit up and think about running in front of the vehicle he starts then props and turns to run the other way, I have seen this many times as the grass gets thinner and the water gets a bit harder to find the roos and emus come on to the side of the road for the feed and moisture during a long sustained drought as we have had during the last 6 years here in south australia the "dawn and dusk" feeding cylce does not come into it any more, the animals have to forage all the time just to sustain life, so if you travel over here be on the lookout at "ALL TIMES" sometimes I think the dead ones on the side of the road are the lucky ones during this period of hardship as they no longer have to struggle I recommend the plastic whistles backed up by a good bullbar, "works for me" the whistles and shoo roo's do not work on emus and they are just as big a problem, be very aware of these they are very fast and come from nowhere to appear right in front of you there is also the danger of the wedgetailed eagles, when they come upon a road kill they will gorge themselves to the extent that they need all the road to get back in to the air again, be very aware of these as well in our northern areas

I have had experience with both and I have my doubts as to their efficacy. I had the whistles on and never hit a roo but then they got knocked off in a car wash and I never hit a roo and the roo shoo blew a fuse and I did not hit a roo.

Much the same as train whistles and flashing lights and bells don't stop accidents at level Xings....

Friend had the whistle type on his car, I had nothing on mine.  When we were travelling with me in the lead and we saw cattle on the side of the road I went passed the cattle without a problem but as soon as my mate with his shoo roo's on the cattle decided to cross the road and hold him up.  This happened not once but 3 times, we passed ok, he had to wait for them to cross the road.

Anything to do with shoo roo's, I don't know.

Howdy;

I used to drive taxis in the Grampians for a little while, anyone who has been to the grampians would very well that the kangaroo population there is around 200,000 Kanagroos to every single human.

Having drove on a 24 hour basis, and been on the roads at all hours complete with said 'Shoo Roo' I can 100% confirm in my experiences and having collected a few roo's they do not work, at all.

I had one incident where there were a bunch of roo's on the road, one came up and sniffed the bloody roo shoo thing, yep it sure works, it attracts them!

I notice others said they work, not sure if this is a mind over matter thing, or they have just got lucky and the roo's in their parts don't like them, as far as I have experienced they do not work and I would tell anyone to save their money and put it into a solar panel or something worthwhile that will give you some benefit.

As Mike said, best to not drive early morning or on dusk when they are mobile.
