Reset Quick use The most advanced and comprehensive fly fishing leader tool online ... well, basically anywhere! Using the form above you can ask LeaderCalc to caculate and show you a number of fly fishing leader formulas meeting your selected criteria.
You can read more about the selection tool here .
LeaderCalc currently contains
2973 leaders for fly fishing, so there are enough to choose from.
Below you see a couple of randomly selected knotted, tapered leader formulas. Click on the name, category or other elements to see more.
Category:
Salmon/Steelhead/Sea trout This particular leader has been specifically modified for seatrout fishing: a 3X tippet following a 2X tippet.
If a 3X is too limp, remove it and use the 2X in its place.
Large diameter, long butt section, rapid mid-taper and short tippet region will turn over flies well [base formula: 50%-25%-25%]
A good leader for seatrout fishing.
