Its rectangular spray pattern covers up to 13 feet wide (6.5 feet on each side), eliminating the dry spots common with circular sprinklers.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003eThe Mark II operates at ultra-low pressure (12 PSI maximum), making it compatible with limited water systems. UV-resistant Japanese polyethylene construction delivers 10+ years of reliable service with minimal maintenance.
