This is a homemade bear deterrent. The main body is made of stainless steel, and the grip is made of a soft sponge material for easy handling. I have made this with care, but it is a handmade item by an amateur, so the cut surfaces of the sponge may be slightly uneven, and the adhesive may slightly protrude. Please understand this beforehand before purchasing. A "bear deterrent" is a tool used to avoid encounters with bears by setting off firecrackers to make a loud noise and alert the bear to the presence of humans. It is used when foraging for wild plants, hiking, fly fishing, mushroom hunting, etc., to prevent accidents caused by bears. This product is not intended to attack and repel bears, but rather to serve as a warning. 【How to Use the Bear Deterrent】 ・Preparing the firecracker: Set the firecracker so that the fuse comes out from the tip of the tube, and light it. Use one firecracker at a time. The bear deterrent has a tubular structure, so the sound is amplified more than when using a firecracker directly, and it can effectively produce sound around the user and in the direction of travel. It is intended to be used when entering the mountains, and also used periodically after proceeding to alert bears and avoid unexpected encounters. 【Precautions for Use】 ・This product is intended to alert animals to your presence and is not intended to attack and repel them. ・This product does not guarantee avoidance of encounters with bears or other animals. ・Do not use it in urban areas or places where people are present. ・Do not use it towards people. ・Use firecrackers one at a time. ・Do not look into the tube if the firecracker fails to ignite. ・Do not use it if you encounter a bear, as it may excite the bear. ・Firecrackers, lighters, etc. are sold separately. ・Use at your own risk.
