What's the difference between a fishing rod of 7.2m and a traditional long rod of 8m?

I don't think it makes any difference. The 7.2-meter fishing rod is even better than the 8-meter fishing rod, which is a comparison. An 8-meter pole is difficult to hold with one hand, so holding the pole with one hand will waste 50 cm. You can also add the length of a hand, and the effective distance is more than 8 meters. A 7.2-meter pole can also catch an 8-meter pole, which is quite different from a 9-meter pole.

Fishing rod:

Fishing rod is a kind of rod specially used for fishing. Generally made of bamboo and reed, the materials are glass fiber fishing rod, carbon fiber fishing rod and nano boron fiber fishing rod. When buying fishing rods, fishermen usually have to consider the fishing waters and environment, as well as factors such as customary fishing methods and common fishing species.
