## Questions & Answers

**Q: Does this have enough output and a suitable tone to be used by an ice hockey referee? Will probably need to wear a mask getting back on the ice soon**
A: Possibly depends on the size of the arena and the size of the crowd.

**Q: Is this loud enough to keep coyotes away?**
A: It's loud enough to get 200 student's attention in for recess so it's probably loud enough to keep a coyote away.

**Q: Could I use this to ref a soccer game?**
A: Yes, definitely loud for games.

**Q: Does it come with a charger?**
A: I don’t know.  But there is a port that looks like a charger would ply into it to recharge.  I have been using this whistle for over a year now and haven’t needed to recharge it.  There is a large battery in it like a 3” long AA battery; not your typical battery.  Sooty this doesn’t completely answer the question.
