If smaller means better, then Nikon's Aculon Rangefinder is at the top of its class. With its ultra-compact size, this new rangefinder redefines portability and is small enough to rival most smartphones. Weighing just 4.4 ounces (without batteries), the Aculon Rangefinder is built to be taken everywhere. Dimensions: 3.6" x 2.9" x 1.5". Multilayer lens coating for higher light transmittance. Long eye relief for comfortable viewing, even with glasses. Easy-to-use, single-button display. The Aculon Rangefinder includes a soft case and a CR2 Lithium battery.
