low vision viewing machine - $280 (bon air)
Autofocus desktop video magnification system.
The machine enables folks with severely impaired vision to read.
The unit is now 4 years old and was never even used. This model currently sells for $2,800, I am asking 10% of current cost.
Please go to opeltec.com site for product info, I am not informed enough to answer product related questions.
No photos of devise available but I did include a nice image of R.E. Lee on his trusty steed Traveler.
