If smaller means better, then Nikon's Aculon AL11 Rangefinder is at the top of its class. With its ultra-compact size, this rangefinder redefines "portability" and is small enough to rival most smartphones. Weighing just 4.4 ounces, the Aculon Rangefinder is built to be taken everywhere. It features an easy-to-use LCD display and is water reistant. This 6x model has a dark green finish.
