If you enjoy a good outdoor adventure, be it a kayak journey at sea, saltwater fishing, or camping, a watermaker is one of your most important implements for preparedness. These devices are trusted and used by the Marines as an essential survival tool. Watermakers use a hand-pumped desalinating method, turning saltwater to drinkable water by reverse osmosis. Methods of water purification have been refined over the past century and harnessed by companies such as Katadyn, a trusted producer of watermakers and purifiers since the 1930s. The Katadyn watermaker 35 Desalinator includes a pump, hoses, laminated instructions, and a portable carrying case. It only weighs seven pounds, is simple to use, and can produce approximately 1.2 gallons of drinkable water per hour. This can easily fit in any small boat or camping pack. If traveling with a large group, watermakers built for higher water production at a faster rate are a smart option. Multiple brands, sizes, and water production capacities are available in the vast inventory on eBay. Get your survival watermaker and be ready for your next adventure.
