From Eschenbach:
The Mobilux® Digital Touch HD provides time and date information, has an automatic shut-off feature after 5 minutes of non-use to save battery power, and 5 contrast modes so users can customize the colors of the text and backgrounds to their individual needs. Magnification powers range from 4x to 15x and include the middle range powers of 5x, 6x, 8x, and 10x. The magnification steps can also be programmed to be smaller or continuous zoom can also be chosen.
Attach the Mobilux® Digital Base (1651-105) to the bottom of the magnifier to create a larger field of view with a lower starting magnification. With base attached, magnification changes to 2.5x, 2.9x, 3.5x, 4.7x, 5.8x, 7.2x, and 8.8x.
The Mobilux® Digital Touch HD has a 4GB SD card that stores photos, which are downloadable to a PC or Mac computer through the included USB connection. When connected to a PC, a live image of what is seen on the Mobilux® Digital Touch HD can also be seen on a computer monitor and can be controlled with 4 icons on-screen. (Windows 10 compatible). Weights only 8 oz. making it very portable. A zippered, crush-proof protective case is included, along with a cleaning cloth and wrist strap.
