I have been working with these little gadgets belonging to Blaine (our instructor) for the last couple of days. What a difference they make - if it looks good under this kind of magnification it looks amazing to the naked-eye. I have a pair on order - I just don't think I could live without them after using them for a few days. The field of vision on these things is just crazy, they blow optivisors out of the water - although they should do for the price! No more crouching over my bench for me, these give the best view about 10" away from the object in focus - and thats the whole object mind - not just the few mm you get with the optivisors.
