This is the magnifying scope that has a submersible lens and flashlight for observing underwater plants and animals. Revealing what lurks below the surface of a pond, tide pool, or even a sidewalk puddle, the scope extends to magnify subjects 4X for a clear, detailed view of everything from scuttling crabs to swaying seaweed. A built-in ruler and thermometer let budding marine biologists take meticulous field notes about specimen size and water conditions, while the flashlight detaches for lighting the path to and from the work site. The lens can be removed for cleaning and the scope floats in case of an accidental toss overboard. Can also be used for magnifying creatures in the sky and on land. Requires two AA batteries. Ages 6 and up. 3 1/4" H x 4 1/2" W x 20" L. (1 1/3 lbs.)
