Here are some trusty tips for getting the right tackle box for your saltwater fishing needs: A saltwater tackle box is going to be bigger than a freshwater one. Freshwater lures are alot smaller than saltwater ones. Obviously this is true because you are going to catch bigger fish out in the ocean or large lake than you would say in a pond.
A freshwater tacklebox would only be effecient for saltwater fishing if you were fishing in a small creek or stream that feeds off of a larger body of water. This is so because when fishing in a stream or small creek that feed off a saltwater bay, you usually will be catching small schooling fish. For example, most striped bass that are in these shallow creeks and streams usually wont go over 2 or 3 pounds. Alot of bass that are caught in freshwater usually dont go over 2 or 3 pounds.
Now when you are deep sea fishing obviously a freshwater tacklebox would be useless. Some of the lures used in deep sea fishing are probably the size of the freshwater tacklebox itself. There are alot of different types of lures and dressings for the lures in saltwater fishing, especially deep sea fishing.
The only advice I can give you concerning the right tackle box for saltwater fishing is to get the biggest tacklebox you can. If you have any problems with it, just consult your local tackle shop or fishing marina and I am sure they can help you.
