The KingScope includes a 20x pre-focused lens and a short nose piece that fits easily into small crevices, reducing the need for grinding on castings, billets, and dies. A slip-on base adapter is offered for additional stability when conducting flatwork. The scope's side opening provides plenty of natural light for viewing, and in low light, a cordless moveable penlight can be employed. The KingScope complies with ASTM E-10 requirements, and NIST standards can be used to verify the calibration.
