If I were doing close up examination work these would be an excellent choice. But my intent for these was to help me to tie small flies onto a leader when fishing at a distance of 5"-10", and the working distance of these are 2" (5x) to 3.5" (3x). They may yet prove useful for fly tying at home
Pros: Well made, very good optics, lightweight,
Cons: Short working distance
