Bear Bell, Magnetic Silencer, Durable Hook and Loop Strap Attachment, Helps To Prevent Startling Bears While Hiking

They are loud and can be easily strapped onto your coat, belt loop, pack, or just about anywhere else you can think of. The features of it is the little magnetic strap that can be easily used to silence the bells. The strap has a small magnet knitted into it, you just have to align the magnet directly with the metal ball in the bell and it sticks to it, preventing all sound. You can make it by silencing your bells when you are around other people on the trail and letting them ring when you are more isolated. 
There is a magnet strap that goes on the bell if you don’t want it to ring, that’s a nice feature that other bear bells don’t have. 
For the dog 
it likes to lag behind on hikes to sniff so it can be hard to keep track of him without looking over your shoulder every 20 seconds. You can tell by the jingling if he’s behind you or walking farther back. It also can let you know when you should stop to let him catch up when it goes quiet and he’s stopped to take a long sniff!
