Zoom Tube Monocular Telescope
The ultra-compact, all-weather Zoom Tube has best-in-class optics and a wide field of view to bring nature closer. Really close. An optional 4x multiplier lens turns it into a field microscope. Weighing just 9.5 oz., it easily slides into a pocket, and the awesomely rugged, grippy, water-resistant ribbed housing absorbs impact.
