Spoon depths

[Chas0218]

Is there an online guide of how much weight makes a spoon sink a certian amount along with line length at 2mph. I have a Precision Trolling book that is great but doesn't have any spoons. I like to flat line spoons with split shots to get them down a little but am unsure how much I need for certian depths. I can stack on my down rigger but would like more than 1 spoon in my spread.

About 4 ft of depth per color at 2mph...

Spoons themselves vary in weight as well, an NK 28 weighs a LOT more than a Stinger of the same length and consequently action at that speed will vary as well.

As a general rule, lighter spoons at slower speeds, heavier spoons at faster speeds.
