Leaving lures and terminal tackle in their manufacturers packaging when possible, is a great way to extend the life of tackle; but also serves another purpose. Keeping them in their packaging makes identifying different size lures and colors a breeze. Sometimes a slightly smaller hook or sinker is what it takes to trigger a bite; being able to look at the packager bag is a good way to quickly pick out the right size.
Pro Tip: Be sure to keep all those old packages and bags. They may be able to be re-used as discussed earlier this week. Also, at the end of the trip it is easy reference to what you need to pick up at the tackle shop next time!
