n-VISION nVISION Hopkins 27512VA Trailblazer Electronic Deer Alert

In Texas, there are deer everywhere, and these work great! I highly recommend it!

The media could not be loaded. I have had these whistles for less than a year, bought them in November of 2020, I bought two and I also bought the adhesive ones you put on the car. Those use the air friction to emit the whistle. I have a history of hitting deer I have totaled out two cars and funnily enough the car in which I have currently is the second car I totaled out due to hitting a deer.Now I was skeptical at first since there wasn't that much popularity back when I bought them but I went ahead and bought a whole bunch because I was scared of hitting a deer again. Better safe than sorry.So I have about 12 of the adhesive whistles on the front of my car and two of electronic ones I'm doing a review for.The electronic ones I use a lot since I live in an area where deer are very common, and they work when I'm not going 60MPH.Since I bought the whistles I have not had any incidents with deer. (knock on wood)But, I wanted to share this video of a perfect scenario of the electronic whistles working.I had no issues with installation, but I have experience working on cars. So its easy to install, but the hard part comes in wire length and battery position, unless you want to wire it somewhere else other than the battery.The switch that comes with it is cheap so I bought a switch from Lowe's and wired it back up with some wire guards.I can't imagine driving a car without whistles now. There have been many times the whistles saved me another insurance claim, and many times I probably wasn't aware the whistles saved me.I highly recommend getting whistles, even if its not this one. Because it doesn't just work for deer.Works for bears, raccoons, fox's, squirrels, birds, dogs, people and etc!

Last year I avoided hitting a small herd of deer that darted into the wooded road near our home. I avoided an accident, but blew out my brake lines in the process! I was driving an old '84 VW Diesel Rabbit and I hate to think what the strike would have looked like. We live in a semi-rural area that is infested/over run with a burgeoning deer population. They have attacked our dogs, destroyed our landscaping, our gardens and we have near misses regularly on our country roads.This year I have declared WAR on the Bast**ds! We are using the Contech CRO101 Scarecrow Motion Activated Sprinkler for the garden and it is working like a charm! Also an AMAZON purchase.We purchased a new Chevrolet Sonic and I insisted that the deer alert was installed as soon possible. It was installed at the dealership, which was a bad idea, but it gave us a great clue as to the two layers of sound that this alert produced. When we picked up the car we could barely hear the alarm at all. The service staff was gone for the day, so we took it home and looked very closely at the full install only to find that the alert horn was enclosed in the hood-latch well, about 4"x 5"! Damn, that was the ONLY entirely metal space in the front of the car that was capable of baffling sound!!! Still, we could hear a hissing-rattling sound in a repeated pattern! Yes, under the high pitched sonic chirp there is the very certain sound of RATTLESNAKE, as the extended product description states. We would not have heard it if the tech had not made a bad choice on the placement.I un-installed the alert horn, reinstalled directly behind the grill and voila` the loud sonic chirp sounded and we no longer hear the semi-baffled rattle, but we know it is there. Deer are avoiding us and I think we should install one on a pole in the back yard! We recommend the alert, and at this low cost it is affordable for all our vehicles.TRY IT! But if you don't install it yourself, look for someone familiar with car stereo installs, skip the dealer!

I installed this on a 98 outback. I live in West Virginia where the deer are thicker then rats. It's more of letting a deer know your around then making them despearse and run the other way. But, it's not 100% effective, and the package tells you just that. It does what it claims to do. I wired it into my high beams,which I think is easier then running wires in the cab to a switch. It lets the deer know you are around , so you are not surprising them. I can recommend this product,but it's not a cure all, you still have to do your part and be viligent. Deer are very dumb animals when it comes to road traffic,there is no 100% way to detur them,this does help a good bit.

Deer in the open as you approach have their heads up and ears cocked and are looking for the source of the chirping. Getting their attention is all any alert is going to do. This likely will not deter a deer on the run that suddenly pops out of the ditch right in front of you. But when you're driving slow this still works while a whistle will not. Was easy to install and cannot be heard inside with the road noise. Just bought a second one for my other car.

Great product, easy to install. Had far fewer sightings of deer and other wildlife since.

これで5個目（友人用2個）の購入です。私としてはとても気に入っています。鹿やキツネ等の反応も良好です。

The noise made by this device can get the animal’s attention, slows them down, and gives you a few extra seconds so react and avoid a collision. We have one on each of our vehicles as we drive almost exclusively on country roads with lots of wildlife. We just got a new truck, and so ordered a new Deer Alert right away. Wouldn’t drive without one!

Best thing I have bought for my car. I hit a deer at 33 miles per hour and the deer whistle only kicks in at 35 mph and above so I nnede something better. This alarm is heard by the deer and they run away from me when I turn it on. Gives me at least another 10mph confidence although I won't stake my life on it and still scan the road at night very carefully.
