Calculate fishing line strength and leader size for target species, technique, and drag setting based on line type and test rating.
Estimate fish weight from length and girth measurements using species-specific formulas when you do not have a scale on the water.
Calculate optimal trolling speed in mph and knots for target fish species, lure type, and desired lure running depth on lakes or oceans.
Published tests express knot strength as percent of line break before knot. Higher is better.
effective strength = line test × knot efficiency %Braid-to-leader knots differ from mono loops. Slippery fluorocarbon may need extra wraps.
Wet line and seated knots usually test closer to real fishing than dry bench pulls.

Compare FG knot vs. double Uni for 30 lb braid to 20 lb leader on bass tackle.
See why Palomar often outperforms improved clinch on 4 lb mono.
Choose a knot that keeps high strength with heavy mono and large hooks.
Multiply line rating by knot efficiency. A 100% clinch on 20 lb line is still only ~20 lb at the knot if tied perfectly.
Pick knots designed for line-to-line joins. Hook knots may cut braid or slip.
See how much line strength your knot retains. Select knot type and line material to compare typical breaking strength as a percent of rated test.
