Oso Grande carries several ultra-lightweight, extremely loud whistles. These are some of the loudest whistles made and because they are of pealess design, there are no little balls inside. If they get wet, you can simply blow out the water and they will work perfectly well.
An emergency whistle is a small item that like a folding knife, should be carried daily. Contemplating the major/deadly earthquakes that are on the rise we think of the people trapped in the fallen buildings. If only they had a whistle to help the rescue workers find them how the outcome would change.
Thanks for such a quality site to shop from. I always enjoy your videos and appreciate the service..
