Im hs swim coach in indoor pool. its me against 40 kids! need loud authoritative whistle, love acme thunderer but is this the right model for my use?

Most swim coaches use the 59.5 but the 63 is louder.

What do the numbers mean 58.5 59.5 60 etc.?

Actually, the Acme website calls the 58.5 the "large" Thunderer, the 59.5 "medium", and the 60.5 "small". Also, the image is supposed to depict the Thunderer 58.5, but it appears to be the 58, so I'm not sure which one they would send to you.

Teuer aber top

Wird beruflich verwendet - ich hab sie mir dann auch vergoldet gegönnt. Die Kollegene, denen ich dieses Modell geschenkt habe, sind auch begeistert… Haptik, Ton, Design - passt alles!

Muy buen producto

Grandísima calidad. Lo malo es que tienes que tener gran capacidad pulmonar. Se te va casi el alma al tocarlo, pero se oye muchísimo.
