The Bresser Optik Biolux LCD Micro 4x Digital Zoom makes it possible for several people to view your findings simultaneously through its 8.9cm (3.5") LCD Monitor.

The device has a memory card slot for SD cards and a USB port. Magnification 40 - 400 fold, the digital zoom goes up to 1600 times (4 times digital zo
