Durable and loud. Just the right pitch and warble to command authority. Ball on the inside can get frozen during very cold weather. If this happens to you, try spraying some dry silicone inside to coat the ball. I would expect that this is common to most whistles of this type. EASY TO BE HEARD – 3pcs super loud survival whistles can provide up to 120 decibels sound guaranteed, can be heard from far distances, and play its role in times of emergency.
