not that i have seen

 

don't know about a whistle...but an arrow through both lungs seems to work pretty well.....

 

Nope!

 

All the deer that I have almost hit (and I mean close enough that I have heard their rear hooves scrape the road) , plus the one deer that I did hit; have all been deer that were startled and running to get away from danger. The deer that weren't afraid and have just stood where they were until I passed have been no problem.

I choose not to add to the number of startled deer by having deer whistles on my bike. Years ago I had them on my truck and I still hit them.

 

I had them on two bikes and never hit a deer, so they work!!!

No, they are worthless

 

Don't know about deer but I have not had one hippopotamus run out in front of me since I put the whistles on. If you're afraid of hitting a hippopotamus then I'll say these things will keep them away.

 

nope sure dont...whats with the animal avatars? about everyone one this page has one..

 

NO ! BUT YELLING DOES ! Hey, fly-by, we're all animals.

 

They do work from my experience! One night after leaving my favorite watering hole I noticed a whole herd following me. When I got home, I told my wife about it, she went and looked at my bike and said " yup, you put the whistles on backwards too! Then she was mean to me and called me a few names I can't repeat here. BUT you can figure it out. The story of my life! Go figure!

Yeah they work after you put the front wheel and the deer whistle up the deers butt doing about 70 mph. That deer never gets in the road again after clean up.
