Overview
The Dr E-BOB4 is a stainless steel fly tying bobbin that holds a thread spool and feeds it through a fine tube, keeping tension even while wrapping thread onto a hook at the vise. It comes in a green finish and is listed for 4 weight line.
This is a single purpose vise tool rather than a rod, reel or terminal tackle item, so its value depends entirely on whether you tie your own flies.
- Stainless steel build
- Designed to hold and feed thread during fly tying
- Green finish
- Listed for 4 weight line
Who it's for
Fly tyers who sit at a vise and build their own patterns, including beginners assembling a starter tool kit. Anglers who only buy finished flies have no use for it.
Pros and cons
- Stainless steel construction resists rust
- Compact enough to carry in a tying kit or tackle box
- Only one color option (green) listed
- No description or owner feedback to confirm arm tension or tube finish
Performance notes
The stainless tube is meant to reduce thread fraying as it feeds, while the hanging spool weight helps keep consistent tension during wraps. Beyond material and the 4 weight line listing, no further spec detail was provided.
