For use on land, the LAND/Shark provides a waterproof one person emergency shelter large enough to provide full body coverage, even over heavy outerwear. It is tough enough to withstand the rigors of a survival situation, yet light enough to not be a burden to carry. The LAND/Shark is a large fully-enclosed shelter (not just a blanket).
It is large enough for an adult plus a small child, small pack or other gear.
Natural materials can be incorporated if available to enhance the insulating properties inherent in its design and construction. Slitting the side seams turns it into a versatile tarp or emergency shelter.
The extremely bright International Orange side makes an excellent emergency signal, readily visible from the air. In a desert environment, itnot only provides vital shade, but its thermal reflectivity effectively repels much of the sun's deadly rays, providing improved performance over a simple shade shelter.
In the water, a LAND/Shark can help extend survival time several fold!
For water survival, the LAND/Shark completely encloses the survivor (with a life vest on), up and over the head, and without impairing any other functions. The drawstring can be adjusted as necessary to protect the survivor from injesting sea water in rough seas. With the rate of body heat loss 25 times greater in the water than air, the bag serves to slow the drain of vital body heat and provides protection from chilling sea spray and breaking waves. This should significantly extend survival times. The aluminized material is radar reflective for search aircraft and high speed vessels moving at night. In warmer waters where the sun is a danger to exposed skin above the water, the bag can be configured to provide for shade and ventilation.
The waterproof construction of the LAND/Shark functions as a deterrent to shark attacks by preventing body odors, waste and blood from entering the open waters and attracting these deadly predators. In addition, the voluminous bag alters the shape of the survivor and reduces flailing movements, presenting a less attractive appearance to predators. The LAND/Shark also provides protection from venomous jellyfish, Portuguese Man-of-War and sea snakes. A tether is incorporated to ensure survivors stay together. A whistle is attached to attract attention.
