Aven's hand-held magnifiers are convenient pick-up-and-use tools for up close inspection. The main lens provides a wide field of view at 10x magnification, while the 21mm lens offers a closer look with 30x magnifying power. Ideal for professional inspection, hobby work, education, reading, gardening applications, DIY applications, and more. Featuring two lenses (10x | 30x), this hand held magnifier can provide a wide field of view, as well as an up-close look at objects. 6 evenly-spaced LEDs surround the 10x lens, while a single LED illuminates objects below the 30x lens. The LEDs can be turned on/off by pressing the button on the handle (batteries not included).
