Query: Solid Whistle with Slim Profile

My experience with the JetScream is that it is a solid whistle with a nice slim profile. For me this whistle performs fine and is consistently loud. The JetScream works well in a busy urban environment or in the solitude of the wilderness. I really like that it is low profile and has a flat design which means that it will fit into a lot of places in my gear or on my person. It is comfortable to wear on a lanyard or clip onto other pieces of gear. I own two of these whistles and have not been disappointed with either one. I carry this whistle with me at all times.This whistle is a great addition to an EDC bag. I recommend the Ultimate Survival Technologies JetScream Whistle.
