This one-of-a-kind tool was created to help the fly fisher bridge the gap between the bugs they find on the water with the closest fly pattern and hook size in their fly box. It includes a compact, collapsible 5-power magnifier and a water proof measurement grid and length-to-hook conversion table.
How the magnifier and measurement card work:
- Place the invertebrate collected from the water and place it on the measurement grid
- Measure from the top of the head to the base of the abdomen
- Use the magnifier to observe and identify the sample
- Based on the measurements collected, use the Length-To-Hook conversion table to choose the correct hook size and type
This is a must-have tool for every fly fisher, naturalist, and fly tyer looking to take their patterns to the next level!
