The Levenhuk LabZZ MG3 Magnifier with Compass is a handheld magnifier with two lenses that measure 3.5" and 0.9" in diameter. The larger lens has a magnification of 3x that helps you to read small or fine print in newspapers or books. Meanwhile, the smaller 8x inset lens, located at the top of the handle, appropriately magnifies very small objects or specimens for study. This magnifier is made especially for kids or young students interested in science. Because of the high-impact plastic and acrylic lenses, it's an ideal tool to use outdoors without concern of it breaking. The built-in compass, at the bottom of the handle, along with a map can aid you in easily navigating unfamiliar territory.
