A 100m (328ft) surveyor’s tape measure is a long-distance measuring tool, featuring a durable open-reel frame, usually made of ABS plastic or metal. Typically made from fiberglass (for flexibility/non-stretch) or steel (for precision), it features dual-sided metric and imperial, clear, and durable markings. Features include a fast-winding handle (often 3:1 gear ratio), a folding end hook or ground spike for single-user anchoring, and ergonomic, high-visibility casing designed for professional construction, surveying, and landscaping
