Loud acoustic signal
Draw attention to yourself. The whistle sends a very loud acoustic signal that can be heard even from a great distance.
With attachment cord
You can fasten the emergency whistle to your equipment, such as to the swim buoy by RESTUBE, to your backpack, or to your key chain, so you always have it with you.
2-tone & very loud
The pitches of the two tones fulfill the standard for life vest whistles, DIN ISO 12402-8. This ensures you can be heard clearly from far away, even if there is ambient noise.
Rugged, high-quality material
The emergency whistle is made of robust PA6 plastic, and therefore extremely lightweight. It is waterproof and floats in the water.
