Was struggling to get my 16months old Malinois with high prey drive above the 80% recall threshold without using an E-collar.I was skeptical at first but figured a $12 investment was worth the try.Wow - Within 2 days of using the whistle we achieved a 100% recall. My only regret was not to buy a second one - this time with a lanyard.

This is a perfect little whistle to stuff in my upper PFD pocket. I bought a small locking carabiner and water-resistant cording, also purchased at REI, to tie to the whistle and carabiner to the zipper handle of the pocket below it, so it is easily accessible if needed. Comes with standard instructions on the meaning of one, two or 3 whistle sounds. It would be nice if those were laminated. But then the product would probably not be as inexpensive.

I have been using the Fox 40 whistle for 29 years. It is my emergency signaling whistle for Back Country camping, canoeing, mountain biking and hiking. It is also a training/ call whistle for my dogs and cats( yes cats can be whistle trained!). I have tried many other manufacturers whistles especially the ones designed to be blown in water and have found that the Fox 40 is still the most consistent and loudest choice. I have never had a problem blowing it in water as it clears itself quite well. I have 7 whistles scattered throughout my packs and house, all hi vis orange. It is probably the best value emergency gear that you can have.
