摘要： An elevated platform configurable for use in cooperation with a tree or pole, or as a free-standing unit. A triangular assembled configuration provides maximum safety and rigidity with a minimum complexity and weight. Interchangeable components, universal connectors, and tool-free assembly result in ease and speed for assembly and disassembly. The platform is adaptable for use in any number of configurations and is transformable into a trailer for towing by a person, ATV, or vehicle. Additionally, a gun/camera rail, bow rack, weather resistant shelter, and a swivel seat provide improved comfort for extended use.
