Thread: Shu Roo?

A whiles back I worked a stint in Inverell, in a two month period driving between Inv and Sydney, mostly after work and into the night I hit 11 roos, mostly swamp wallabies, the biggest hit was at the posted speed limit, long grass, roo jumped out, one bounce half volley into bar... didnt even come off the pedal, roo flew off into the grass... In all that the only damage to the vehicle was one smashed indicator which I glued up with araldite.

So who cares about a rooshoo, however i would be interested in a "bloody big brahman bugger-offer" would be handy when driving to Cooktown. They would make a real mess of ya.

But getting back to rooshu, not sure on efficacy but friends in Inverell removed theirs (helped by a swamp wallaby) after a drought they were finding on dusk the macropods would all gather at roads edge, youd come over a rise and see 8 roos scattered near the road, without the shuroo they would invariable bound off, with it on there would be blind panic roos everywhere includinging straight into their pretty ute?

anyway Ill stop rambling now!

I have a Shoo Roo on my "Phantom LR" - read Mazda 626, which was installed when I lived in country NSW. As a geophysicist, I reckon they can (do) work - but they don't always work - its like the old adage - never work with Kids or animals - they can react in many ways - what do I mean?...

As I'm sure you are aware - this device "works" by emiting a 25,000Hz or higher frequency which is above the human hearing register but perfect to alert Roos, who do hear higher frequency sound. We can hear a Sho Roo as they also build in a lower frequency component so we (humans) can tell that they are working (and to annoy people etc).

A car travelling along at typical highway speeds emits low frequency sound that the Roo doesn't hear - so the Sho Roo "works" by the fact that it can hear you coming - but whether or not it then actually gets out of the way, or decides it is still hungry, so bugger it, I'm staying put here and eating this grass, is another story.

That said - I never hit a Roo once I had one - hit plenty without it.

Also used on virtually all metal ships and boats that are permanently on the water, and used extensively in industrial situations. They all have one thing in common - the metal being protected is totally immersed in water. I know from experience that while electronic rust prevention stops the outside of my boat from corrosion below the water line, it does nothing for it above the water line, nor does it stop it from rusting from the inside. So go for it if your car spends its life below water.

See? Firey topic

Slowing down is not always totally effective - last damage I suffered from a roo, I had slowed to about 20kph to allow a mob of them to cross in front of me - and one that I did not see hit me just behind the LH back wheel doing about $500 worth of damage (not yet repaired). This was in broad daylight in perfect visibility.

On the mater of the elctronic rust preventer. We don't have it for cars in the Uk. So this is a new thing to me. Why the uk does not is a mistry to me as we have a mayor problem with rust, maybe because it is crap.
I ask a rep for the company that sell them how it works (when i was working at Southaide Land Rover). He said to me that it puts a negative current thought the car chassis and body.
To which i replied , What like the battery does. At that point he turned and walked away from me

It would be interesting to see how electrical rust protection would work on Landies, even immersed in water.

The principle is to have a sacrifical plate which is forced to corrode by placing current through it (I remember now - it's a sacrifical annode).

BUT - the plate has to corrode more readily than the metal it protects. In theory this applies to steel/aluminium combinations - the aluminium will corrode in preference to the steel. But we all know which part of the Landie corrodes first.

And the current has to return to the cathode OUTSIDE the vehicle. It just might work in a wet, salt-encrusted UK vehicle.

My point is that a Shu-roo will work in theory, as does electrical rust protection, but the real world is something else entirely. But the Hiclone doesn't work, in theory or in practice. (Dons hard hat).
