When I told the boat captain to check the line, he discovered that one of the ceramic line guides had developed a crack, and it was nicking the line each time it touched the crack. Finally, the damage to the line was too severe. That rod was taken out of service, but we never got another big bite that day. That incident is why I check my line regularly for fraying and my rod guides for cracks or chips.
One of the best ways to check for flaws in the rod guides is to use some kind of fine material that will snag on the imperfections when run through the guides.
Ask your wife or significant other for a pair of old pantyhose and cut off one leg. Take that hose and run it through the line guides. If there are any imperfections, the hose material will snag.
For the guide tip, you will probably have to cut a smaller piece of the hose to get it through the guide, but that guide tip is the one that gets damaged the most often.
If you find a flaw, take that rod out of service until you can repair it yourself or take it to one of the numerous bait shop/tackle stores on the Alabama Gulf Coast to get it repaired professionally.
Trust me, you won’t be sorry you have perfect rod guides the next time you have a big fish on the end of the line.
