Rigs Lab · Gear & fly fishing rigs + leaders
The rig builder and library for fishing. Lay out every cut, knot and turn to scale, start from a photo of a formula in a book, on a website or in your notebook, then publish it for anglers everywhere to tie, clone, share, print and fish.
Build it to scale
Every section, knot and turn, drawn the way you tie it, with the cut list worked out for you.
Start from a photo
Snap a formula from a book, a website or your notebook and it comes back as a rig you can edit.
Test it in the tank
Watch it drift, sink and turn over before it ever touches the water.
Share it, print it
Publish it to the library, send the link, or print a card for your vest.
