About this item

Product Description Used all over the world by antenna installation technicians, surveyors, engineers, miners, architects and many others to measure bearings quickly, reliably and easily. Amazon.com The Suunto Tandem is a liquid-filled precision compass and clinometer that's an invaluable tool for surveyors, engineers, cartographers, geologists, miners, and anyone else who needs to measure directional indications, heights, vertical angles, and slopes with speed and accuracy. The dual-purpose unit--which comes in a water- and impact-resistant aluminum housing--includes scales in both degrees (0 +/- 90 degrees) and percent (0 +/- 150 percent), along with a conversion table (cosines 0 to 45 degrees) and an optical adjustment for reading. The device is particularly handy for surveying and construction projects, as it overcomes obstacles or depressions in the line of vision. And users who need to establish GPS communication or install and position a satellite antenna will love the Tandem, as it helps in establishing the right direction and correct angle and helps ensure that nothing is blocking the satellite signal. Additional features include a high degree of accuracy (the Tandem delivers precise readings in seconds), 90-degree edges for contact measuring, a lanyard, and a convenient carrying pouch with a belt loop. It's also simple to change the Tandem from compass to clinometer--all it takes is a click of the wrist.
