SAGWATCH

The principle of sagging by wave-timing has long been recognized. The use of the Sagwatch to determine sag simply, rapidly, and accurately can save many valuable man-hours by eliminating conversion tables and the setting and sighting of targets. This high-quality instrument has a 7 jewel Swiss movement in a stainless steel case. It is water resistant, dust protected, shock resistant, antimagnetic, and self-compensating with an unbreakable mainspring. Logarithmic scales are calibrated in feet and decimals for both 3rd and 5th returns of a mechanical wave providing direct reading of sags up to 100 feet.
