KEY:

depth of indication on fish finder 7. 30# Fire line dia. .015
trolling line length 8. 50#Fire line dia. .019

35#Spectron dia. .0165 12. 60# Spiderwire dia. .013

The figures above include 2’ of depth for a medium weight lure, 6 to 10 ounces and a 30’ mono leader. Add 1-2’ for a heavy lure, eg. A MoJo and subtract 1’ for a light lure below 6oz/ Fine-tuning as components change, eg. 12’ fluorocarbon leaders vs. 30’ mono can only be done through experience. Depths are for a boat speed of 3mph. For 2.5 mph multiply depth by 1.3 and for 3.5 mph by 0.8.
