Field Kits and Inspection Desk Field Kits organizes focused knot practice. The new Inspection Desk records product identity, history and observed condition for a clear handoff, with uncertainty kept visible. 1. Open Browse → Field Kits. Build a named set of up to 12 knots, follow guides and mark self-reported practice. 2. Open Beyond → Inspection desk. Identify the product and instruction source, record history and condition, then freeze and share the brief. 3. Open Beyond → Load worksheet for arithmetic using a documented product rating and your own identified divisor. 4. Read Strength evidence for the information needed to assess a real product or test result. Generic knot-strength percentages and annual UV-loss estimates have been removed from the interface. The app does not approve equipment, calculate remaining rope strength, determine a working load limit or certify competence. An inspection brief is a self-reported record. A worksheet quotient is arithmetic only and models no knot, termination, dynamic load, wear or system interaction. Follow identified manufacturer instructions and qualified guidance. Field Kits holds up to 20 kits. Inspection drafts last for the current visit; export to retain them.
