It is as powerful as many small binoculars, but unlike binoculars it can focus on objects as close as five feet — which also makes it great for poking around in museums, etc.
A great plus is that it can be used (with the included attachment) as a 30 power microscope to inspect really small things like slivers, tool edges, or spider mites on your plants.
Complete with a hard-shell case for storage. Metal tube with glass optics and a 10mm objective lens. Measures 5" overall; 7-1/2" with microscope attachment.
