Take a closer look. A MUCH closer look. Ivation presents this distinctive 10X lighted handheld magnifier designed for jewelers, hobbyists, collectors, treasure hunters, mechanical tinkerers and all those who enjoy inspecting the finer things in life. The magnifier's star component is a precision crafted circular optical lens that's set in a 30mm (diameter) metal encasement. When rested directly on an object, the lens accurately magnifies it by as much as ten times its actual size without sacrificing clarity or color integrity. This is of great interest to jewelers who always require true-to-life color even when peering through a loupe. 3 Bright LEDs Light Up the Finest Details While weighing in at just 7 ounces, this Ivation magnifier manages to pack a full-power LED lighting array. The 3 bulbs are neatly built into the underside of the eye rest so to spare your eyes from the direct light. The shine is instead aimed across the entire filed of view and focused on the object you are inspecting. Power is supplied by way of 2 AA batteries (Included) that hide from sight in the most inconspicuous and elegant manner: They're stowed away within the sleek metal handle. and the batteries do not require frequent replacing. Features: Measuring Scale; Support Post Although you're using a magnifier to see things bigger, you often still want to know the objects' actual (i.e. non-magnified) dimensions. This magnifier therefore features a dual-unit measuring scale that's etched into the inside of the viewing chamber. Whether you're appraising or repairing jewelry, authenticating documents, or working with art, you'll appreciate the 0.5mm and 1/16" guiding rulers. Another nicety is the freestanding support post at the end of the metal handle to allow you to use the magnifier without having to hold it.
