deer whistles

What do you think about deer whistles on your truck or car? Do they work or not? Just thought I'd sample your opinions around the country on this rainy day in Indiana. Thanks, Pat
 
They worked on my truck.

Ran into somebody that had them on their truck and they worked great, except they were in a steep canyon once and the deer couldn't go up so they came down and splat.
 
One time as I was in preparation to change to another truck within the company I worked for the previous driver said I owed him the cost of the whistles on his old truckcause he just had put them on.

I ask him if they really worked , He said ya don't see no deer hair on it do you?

Just bought him breakfast and called it even.
 
Used to have a FedEx Home Delivery route in rural Iowa. Put the deer whistles on the truck first thing. 4 out of 5 deer did not care, just kept coming-supposedly the deer stops at the racket-the 5th one was already dead. My vote is keep your money for the deductible! Greg
 
I always chuckle when this subject comes up.
One question: Has anybody here every had an insurance agent give a discount because they've had deere whistles on their vehicle? (Crickets chirping)
Some of you need to research this before deciding for yourself.
 
This Saturday is the opener of gun deer season in Wisconsin.

We like to mount the deer whistles on our truck "backwards" and drive down the fire lanes. This attracts the deer to the road for easy pickings.

LOL
 
A couple years ago I saw a news program try them out. They couldn't prove they worked. When they interviewed the company that makes them their reply was you didn't prove they don't work. So I guess it's up to you to believe in them or not.
 
handled auto claims for few years before we hired another appraiser, looked at lots of cars that hit deer, had whistles on bumper with deer hair stuck in em, or broke off by deer body, IMHO save your $5, Mark
 
Several years ago I drove a Tractor Supply Co. truck. TSC claimed they dropped from 100+ deer/
truck accidents per year down to less than 20 after installing deer whistles on every
delivery truck. It
was a firing offense to leave the yard without cleaning the bugs out of your deer whistles. I never was able to learn if there was a "better"
brand of deer whistle though.

I have a Cabela's
12v active deer whistle on both of my pickups. Deer appear to hear them better than passive whistles that depend on air flow. The instructions on the active whistles tell you that
after the deer hear their whistle, they cannot
predict what the deer will decide to do next, but
they recommend that you honk your horn and slow down. I haven't hit a deer since I installed the active whistles, but I never had hit one hard enough to cause vehicle damage before either.
 
My wife got a big doe with her Mercury,deer whistles were on the bumper.Old time deer hunters tell me a moving deer will stop if you whistle at it.
 
The deer come out and try to blow on them !

My old boss/body shop manager said he saw alot of hits with them. They were good for business.
 
Bought a pair whistles and put them in the backseat, drove to Des Moines and back about 400 miles and never hit a deer.
 
my daily comute is cross country @ 5:00 am thru corn country, her is what i have seen. if they are standing around grazing without whistles they raise there heads up and watch me go past, with whistles they usually start walking away from me.
if they were running before i approached them, the whistles make no difference, they keep running the same direction. in eight years i have dodged em all. knock on wood.
 
I once put a couple of those on the wifes car. She finally noticed them and I said i put them on there a few months ago. She asked what they were? I said metorite deflectors, she of course laughed and said now way. To which I replied that she had not been hit by a metorite since I put them on there. So they must work.

I figure they work about the same way with deer. Might be a bit better than not having them I guess.
 
Guys, I appreciate all the replies. Got about the reactions I thought I would. I especially loved the one about having them in the back seat and working perfectly on the trip! Thanks. Pat
 
Thats a big negatory. They do not make enough of a difference to prevent a collision. The deer are acustomed to hearing the noise after a flooded market. I just received a PDF file from INDOT today with the same information. Save your pennies.
 

Snake oil. If a deer can't see a vehicle or it's head lights. And of the deer can't hear a vehicles tire, driveline, exhaust and wind turbulence noise. How is some little piffle of a whistle going to be noticed let alone scare the dear away?
 
Several years ago the Wisconsin State Patrol
tried them out on patrol routes in high deer kill
areas...they got no conclusive evidence and said
"save your money"
 
I work at the University of Mississippi's National Center for Physical Acoustics. (research with sound). Here the general consensus is that the little passive plastic glue-on whistles sold at store counters are a waste of money. The only ones that could possibly work would have to be powered, and powered enough to overcome the pressure level of the vehicles motion down the road. Stick your hand out the window, that pressure. The little whistles sound is never heard, just blown backward into the grill and lost in the noise. To be heard by deer ahead down the road, the whistle would have to have high pressure power, ie via electrical amps or air power, and have enough power to overcome the wind pressure present. And then nothing says the deer would move or be spooked by a loud noise, they respond differently in tests. The time honored safety response is hard braking in a straight line, with horn and lights blinking. The killer is swerving and body roll. Paul in Mississippi
