Fishing Pole
There are fishing poles in all sizes, from the small toy-size rod and reel, to large surf rods. Choose a pole that won't be too large for the child to handle. If it's too big, he won't be able to handle it correctly. If you choose a rod that's sized for his height, he'll be able to learn to use the rod correctly and as he grows, he'll be able to use a bigger pole quite naturally. They range from around $12 to over $50.
Tackle Box
Buy the child a tackle box and fill it with the basic items he'll
need to fish. Nothing will make him feel more proud than knowing he has his own tackle box and won't have to rely on yours. Purchase various hooks, bobbers and fishing lures to place inside the box for him. Fishing lures come in every form from plastic frogs, to worms and crayfish, so there's something out there that will fascinate your child, even if he doesn't catch a fish with it. You can also usually find small charts listing the various fish that you can find in your particular area. This will be interesting, as well as educational, for the child. He'll also get to know what the various species of fish look like. You should be able to find a small and rather inexpensive tackle box at your local department or outdoors store.
Fishing Trip
Buying all the neat fishing gear is great, but nothing will express your love like planning a special fishing trip for the child and yourself. You'll be able to experience the thrill, as the child uses his fishing pole and tackle for the first time. It doesn't have to be a big, expensive fishing trip. Even a trip to the local river or fishing hole will be good enough. You'll not only build his confidence in using his new fishing equipment, but you'll also be building your relationship with your child.
