4X4 PRO IS Everest-D V5/V4->

Earlier versions of the 4X4 PRO embossed braille in automatic book format (saddle-stitch) where as Everest embossed only single or double-sided braille. However, upon the release of the V4 embosser line in 2011 the 4X4 PRO was discontinued and the Everest became Everest-D. 

The convenience of the automatic book format of the previous 4X4 PRO is implemented into what is today the Everest-D V5 or V4. The Everest-D has additionally kept the same standard features and great low price of the previous Index Everest braille embosser.
