Typically ships in 3–5 business days.\u003c\/p\u003e\n\u003cp\u003eA 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.\u003c\/p\u003e\n\u003cp\u003eThe 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.\u003c\/p\u003e\n\u003cp dir=\"auto\"\u003e\u003ca href=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0719\/9476\/9486\/files\/Website_Manual_Short.pdf?v=1790883923\"\u003ePreview the manual. \u003c\/a\u003e(Full PDF emailed with the disks).
