I had some trouble finding a Fox 40 wistle locally when I was getting ready for an extended canoe trip. It was required to have a wistle to clip to your life vest for the trip. This site led me to look for a pea-less wistle. Most camping departments that I looked in did not carry a pea-less wistle. I found that the sporting goods department in most stores carry the Fox 40 for referees. Also look in the fishing/canoeing area of places like Gander Mountain, but don't waste time looking in the camping gear. The camping area only had wistles with peas.
