I'm looking for a fishing pole that can work for fishing trips to the ocean as well as lake fishing. I fish a lot in New Jersey (surf, bay, boat) and also visit lake Winnipesaukee quite a bit. Is there something that would work for both? I haven't purchased a new pole in years.
Much depends on what you are fishing for and how you are fishing for it. I was an avid freshwater angler for almost forty years before my wife and I moved to Florida, and I have the garage full of tackle to prove it.
What I found when I got here is that my lightest freshwater combos were too light for most saltwater fishing. Probably the most practical combo I have now is a 7 foot medium-heavy spinning rod with a 400-class spinning reel. I use it for everything from panfish along the beach to snapper fishing in the gulf.
I have another rig for heavier fishing, like reef fishing for grouper. It's a 5' 6" boat rod coupled with a Penn Senator reel.
Given enough line capacity and lack of obstructions and snags, you can land surprisingly large fish on light tackle. My best to date is a ~28# barracuda caught on what the charter boat's mate called the "Snoopy rod". It was a light action freshwater rod meant for bass, walleye and panfish in fresh water.
