Customer Review

It is perfectly operational in extreme environments.
I use it in the context of passive safety for underwater sport, it is used to signal to the surface of the water if the sea is rough and the boat is too far out of sight as a shrill whistle wears away the voice.
This model is ideal and has an excellent reputation.
It's a good product.
