My lifeguard company uses Fox40 whistles and they work great! They have a loud and shrill sound that cuts right through crowds of people. It can be heard from across the water park and through walls. Mine has stood up to over a year of my whistle-chewing habit.

Good price, just what my son needed for lifeguarding

Its a good whistle I like that there's not ball in it and that its plastic so it lasts a lot longer And won't rust.

My son's job as a lifeguard requires specific equipment.  I can always count on SwimOutlet.com to have just the right stuff!

This is a loud whistle that is hard to ignore.  I bought it because I teach P.E. to elementary students and need to get their attention when they are over 100 yards away on the "far field".  This whistle does that.

Always works. No pea to malfunction.  Good tone and range.
