After a brief understanding of the price of the power surfboard, let's take a look at how to buy the surfboard.

1. Weight and technology:The heavier weight, the larger the board, 60kg: 7.2-8.0 feet, 70kg: 7.8-8.6 feet, 80kg: 8.2-9.2 feet, 90kg: 8.6-10.0 feet.The larger, such as more than 7.8 feet.

Unit conversion: 1 feet = 30.48 cm, 1 -inch = 2.54 cm, such as 8 feet 6 boards, equal to 8*30.48 6*2.54 = 259.08 cm.The difference between the board and the 9-foot board 12-6 = 6 inches = 15.24 cm

2, wave condition:The large waves are used to use small plates, and small plates are flushed.

3. Material:It is mainly divided into inflatable boards and glass reinforced plates. The inflatable plate is mainly drawn with brushed substrate for core materials. The price is cheap and easy to carry. After inflatable, it is the same as the hard plate as the hard plate. After dual pressure reinforcement, it is not easy to break and will not leak air.The cost of glass fiber reinforcement plates will be higher. The mainstream is to use EPS to foam as the inner core. The glass reinforcement bottom is wrapped in two Levels. The epoxy resin is applied to make the plate body tightly pulling force, and it is more abrasion and not easy to break.

4, arc:The novice buying board must find the arc, the arc runs fast, it is better to do it, it is more suitable for novice.

5. board head:The head of the board affects the appearance. It is more stable when riding a little, and the pointed movement is lighter and more flexible.
