Developed using composite materials for the body, the ComPro is a lighter, more affordable alternative for transit users. It incorporates a cast NdFeB, rare-earth magnet, precisely balanced on a sapphire bearing. The result is a powerful magnet, which seeks magnetic north very quickly and allows for faster readings. Call us for special balancing. Single NdFeB magnet resists demagnetization better than other types of magnets for increased reliability Azimuth accuracy ±1/2° with 1° graduations Vertical accuracy ±1/2° with 1° graduations and 10 minute readability Vertical angle measurements to ±90° or 100% grade A percent grade scale with increments of 5% Induction damped needle for quick, accurate readings Sapphire jewel bearing allows for smooth needle movementMagnetic declination adjustment allows for east or west declination setting to 180° Short and long sights for increased accuracy when sighting azimuth or vertical angles Precision aligned mirror with convenient "see through" sighting capability Composite body material is permanently impregnated with color O-rings make the Com-Pro waterproof for increased reliability One year warranty 0-360° Olive drab body color GI issue composite plastic case
