A dual loop regulator is configured for improved regulation of a supply voltage for a dynamic load based on the magnitude of changes in the load voltage. The blind is ideally of a light weight material, such as plastic, and includes adjustable angles for natural cover, and a number of vegetation straps that adjust to any natural cover the hunter chooses to use, such as grass, corn, brush, or tree limbs. The substrate coating not only is easy to clean, has good wearing performance, and provides a smooth surface, but also has better adhesion to prevent peeling off.
