I have this whistle, my section loves it but I’ve had a friend get some complaints in a different section, it’s all about timing. Can’t use it all the time just on big downs, when I rewatch games at home I can hear it clear as day on TV haha
I bring alot of pennies for a can noisemaker, the hyper whistle “beast whistle”, and a plastic fox 40 whistle (sold at Walmart). Both whistles are entirely plastic so you can get through security easy (make sure all plastic since whistles are technically not allowed but I’ve never gotten complaints for them).
We’ll polish off 25 oz beers in the 1st quarter then use the pennies to make a noisemakers, we primarily use the fox 40 whistles and then the beast whistle for big plays, you can only use the whistles when the crowd is getting loud or you’ll stick out blatantly obvious and probably get complaints. Also be weary of anyone in front of you when using the beast whistle, I’m tall so luckily get away with it but it would destroy someone’s ears if clearly in the the line of fire
