EmNav NAVIGATOR

Analog Navigation Instrument

EmNav NAVIGATOR

$189.00

Analog aid for training and emergency backup — not a certified primary navigation system. Drawings are representative; production disks may change.

Made to order. Typically ships in 3–5 business days.

A 5.95-inch laser-engraved circular instrument that combines a Bagnold-style sun compass, logarithmic C and D scales, deliberate-offset math, a clinometer, and an Equation of Time / sun-declination plot in one pocket disk set.

The NAVIGATOR is the full EmNav system: a Base Disk, a 4.5-inch inner small disk, and dual index arms. Rotate the inner disk to multiply, divide, convert, and chain land-nav problems the way a circular slide rule always has — then hang it from the gnomon eyelet and steer by the sun. When GPS dies or you simply want a backup that cannot be jammed, this is the instrument you reach for.
