Line Calculation

 

 

 

 

This Line Calculation will take our line capacity for certain reels and let you pick another line to figure out how much it will hold. This is only an estimate.

Fill in the Reference Capacity for the Diameter for the line and the Capacity

The Boss 270 holds 300 yards of .018 diameter monofilament. So you will put .018 in the Reference Diameter and 300 in the Reference Capacity. Now find the diameter of the line you are looking to use on an Accurate reel in the chart on the right. Lets try 15# monofilament. Now put .015 in the Capacity Diameter. You will now see the Capacity amount for 15# line on a Boss 270 reel.
