A tour guide was attacked by a crocodile while in the waters of Rio De La Plata, North of Cozumel, Mexico. Both of his legs were injured, and lucky for him he was able to shake loose of the crocodile. He was transported to San Miguel Medical Hospital.
As a maritime occupation / water sports tour guide it is in your best interest and the interest of your customers to carry first aid equipment. At the bare minimum a tourniquet specifically designed for the water should be carried. OMNA makes a wearable tourniquet called the Amphibious Tourniquet specifically engineered for marine environments. A Tourniquet designed for where you will use it, has more value than a committee that may have numerous conflicts of interest influencing their product recommendations.
