Description
Requires more than a certain amount of blow Please be aware of children and women.
An excellent product that can be used without changing the volume even when wet.
This is a professional whistle that is known for its light and loud volume.
It is designed to produce loud sounds, so when you blow, it can sound up to 328.3 ft (1,600 m) away.
It is loud so please be careful to irritate your neighbors and your ears when using.
No moving parts (such as balls) that can jam, freeze, harden or break.
The tone is composed of three sounds.
The little whistle feels like three pieces together. The resistance of the blowing is less than the same type of mini, and the sound is slightly loud.
The size is a little larger than the mini, but I do not feel at all about use. Rather than a larger one, we hope you have a sense of security.
This whistle has been used for many years and is reliable with sound quality and sound quality for a long time. We recommend it with confidence.
This whistle is used for lifeguards in the oceans and pools of America. They are often used in schools.
In Japan, firefighters, law enforcement, maritime security agency, self-defense forces, and life savers.
Note: Weak blowing will only make a hazy sound.
