Anyone ever use a clip on line counter to calibrate by attaching to your line counter rod/reel set up? I did that and pulled out 50', then compared the difference between the 2 and got 2.5 ' difference and 3' difference on 2 rods spooled with 15# filled. Doubling and adding a couple feet because the reel dia. will get smaller as more line comes off that puts me at about 6-8 ft off of true line length. Does anyone see why this will not work? TIA! My line counters were 2.5 and 3' short of true.
