For me a novice trainer this whistle makes the same clear consistent sound every time. Just take a breath and use your tongue as a valve, very easy to use right away. My Chessie can hear it several hundred feet away. It can be easily held in your teeth while still being able to talk. I have tried another dog whistle with a pea and never got the knack of using it and gave up with it. My next order I am getting a spare just in case.
