RE:Magnifying Lamps for Tying
Hi! This is Ron from Monomoy (finally!).
I would be totally lost tying trout flies without an Opti-Visor. It's basically a plastic headband with a hinged flap holding a lens. You can see it in Hunter's Fly Tyer's Catalog 2001 on page 33. I use the #3 lens which magnifies 1.5X. I have been tying 22's without too much trouble.
I've had mine since the mid 80's and have never found anything better. I would have brought mine to UFT to show you but I don't think I will be able to make the next meeting.
Let me know if you have any questions.
