Want to see what's going on underwater when your kayaking on that clear river, tropical reef, or seagrass bed? It can be hard to see through the turbulence and glare on the surface. Remember your science? a viewing box or bathyscope makes it possible to see through the waters surface. The Crystal Kayak Company's clear kayaks are made of a proprietary six millimeter thick Lexan polymer from Spain with Gin like clarity. Unlike many cheap replicas this true high quality clear canoe / kayak hybrid is fitted with a corrosion resistant anodized aluminum frame. Also comes with two seats, two kayak paddles, and two inflatable air chambers that works as flotation devices for the kayak. Bulk orders are great for hotels and water front resorts, kayak rental companies, and vacations homes.
