Hopkins' nVISION TrailerBlazer Deer Alert is 10x safer than traditional deer whistles. The Trailblazer Deer Alert won't clog up like traditional deer whistles either. It's easy to install and easy to keep hidden from view.
We have 2 Auto's Both have 3 on each ,they really work deer stop and listen
By installing 3 the sound throws 3 different times much more coverage. Highly Recommend this product for your pease of mind on Road driving we live in a country area loaded with deer ,,we've seen these work time and time again. Thank You John PS These come with a switch to turn on & off at your discretion! They Draw People attention also!!
Seems to be effective...I have seen deer stop in their tracks and just look for the noise and haven't hit any deer in an over five thousand mile trip from MN to CA and back. Can be a bit distracting when conditions are quiet, on smooth pavement and speeds below 60 MPH you can hear the Deer Alert inside the vehicle unless you have some audio playing at moderate sound levels. One of the three units I have purchased came with a defective inline fuse so it initially did not work. The fuse looked good but when tested it had no continuity. A bit hard to find a replacement as it is an old school glass automotive style that is shorter than standard. A local trucking firm has installed these on their entire fleet of eighteen wheelers and have dramatically reduced the number of deer strikes from a couple per week to only a couple per year. So I have installed on all my vehicles.
HAVE NOT SEEN ANY DEER IN THREE WEEKS. BEFORE I GOT DEER ALERT I SEEN SO MANY DEER AT NIGHT HAD TO SLOW DOWN TO 35 TO 45 MPH MY ROUND TRIP IS 120 MILES PITCH DARK ROADS TO Blue Mountain NEW YORK THIS DEER ALERT ITS THE BEST FOR THE MONEY IT WILL SAVE YOUR CAR AND YOUR LIFE. WHILE DRIVING BE ALERT AND KEEP YOUR EYES MOVING
