Bushcraft & Survival Emergency Life Boat Whistle
If you want a emergency whistle then this is the one to have. There are very few on the market that comply to the new safety standard ISO 12402-8.
This is the one used by most airlines in life jackets and marine survival kits in life rafts as it complies to the correct safety standards.
It is lightweight non-corrodible whistle which will float in sea water, it has clip for attaching to you and also comes with a lanyard hole.
Meets the New Safety Standard ISO 12402-8!!
