Custom Mortgage Calculator Wheels

Derive an immediate solution to all speed-distance-time problems for answers in nautical or statue miles.  Calculate speed in knots or miles-per-hour; time in hours, minutes or seconds; and distance in nautical or statute miles (or yards if desired).  It's a norm for the U. S. Navy.

Circular slide rules eliminate "off-scale" calculations, because the scales were designed to "wrap around"; they never have to be re-oriented when results are near 1.0—the rule is always on scale.The basic advantage of a circular slide rule is that the longest dimension was reduced by a factor of about 3.

A customized nautical slide rule so easy you'll never get perplexed. We offer a foolproof immediate solution to all common speed/time/distance problems, convertible to statute or nautical miles. This slide rule even allows you to compute distance in yards if the speed is factored in knots. Need a different item? See our Catalog for what we have.
