Marine version of our red and yellow slimline whistle. As the ring is NP brass then it does not rust.
SOLAS (Safety of Life at Sea) approved.
Easy to blow, sound carries very well
Distinctive in red & yellow.

This whistle in red and yellow is exclusive to us. It is a higher specification that the standard whistle as it has the Marine ring that will not rust, however instead of buying them in dozens we buy them in 1000s so these are the cheapest version.
