They can either be wood or aluminum. I encourage you to use a wood one. If not, I will make fun of you like I do my good friend Bill Booker at LaSalle-Peru H.S. for using his aluminum one. If you choose the wood fungo, I would recommend taping the barrel. If you hit a good number of fungoes, the tape will increase the durability of the bat. I took the tape off of one once. The barrell was like sawdust, but I re-taped it and it was ready to go. One season, I figured it out, between the high school, American Legion, an junior high seasons I had hit over 10,000 fungoes. Tape it up!
One of the major advantages of wood fungo has to do with the feel of your hands. While the metal ones feature a conventional metal bat knob, their wood counterparts usually come in 2 knob designs. The conventional metal-bat style knob is excellent for folks whose hands are sweaty. The flared knob is amazing for those that do not want the knob beating their hand’s bottom which is uncomfortable during practice.
Once in a while, veteran managers revive it. The Giants took infield occasionally in 2008 and 2013 under Bruce Bochy, and Jim Leyland instituted infield drills before batting practice late in his tenure in Detroit. Molitor, for one, misses it. He took infield even as a designated hitter late in his career because he hated sitting around for almost two hours waiting to play.
A fungo bat's size and weight make it easier to operate with one hand or two. Coaches can toss a ball up with one hand and hit pop flies or ground balls farther and with greater accuracy with a fungo bat than with a regular bat. According to an article by LJWorld, high school baseball coach Brad Stoll said fungo bats allow him to hit more balls because heavier regular bats would "wear you out." Fungo bats should be used as a practice tool only and should not be used to hit a pitched ball.
The main goal of the game is to hit it to the pin in the least amount of strokes, similar to golf. Holes can consist of a certain sign in the outfield, in the tarp tunnel, off of the foul pole, onto the pitchers mound or off of a yardage marker on the outfield wall; it can really be anything on the field that can be hit without breaking. There can even be 2 part holes such as: First you have to hit the ball off of the scoreboard, then you have to hit the ball off of the right field foul pole.
