The Elan E64-8x4K is a rugged, king-size field book measuring 6" x 9", designed for heavy-duty surveying work. Its waterproof bright orange vinyl cover stands up to harsh conditions, while the extra-stiff backing provides support for writing in the field. Each king-size 6" x 9" book includes 160 pages of white ledger paper made from a 50% cotton blend, designed to be water-resistant and archival-quality. The left-hand pages are ruled with eight vertical columns in light blue, while the right-hand pages feature an 8x4 grid with a red vertical center line. Printed with waterproof blue and red inks, this field book resists smudging in wet weather. It also includes an 11-page appendix of conversion tables, trigonometric functions, and curve-solving formulas for quick reference in the field.
