A strong addition to any library or office, the Eureka carries an up-to-date blue-ocean map with more than 4,000 pieces of information and raised-relief topography you can feel. The 16" ball sits in a gyro-matic meridian on a black metal tapered base, letting you tilt and rotate it to view the world from any angle rather than a single fixed orientation. Substantial enough to anchor a room and detailed enough to reward close study.
