With the maturity of technology and the opening of civil and mass consumer markets, several manufacturers are striving to be the "DJI" in the field of consumer underwater robots. There are mainly Jiying Technology, Zhendi, Shenzhilan, Weifu Intelligent, etc. These Jiying products have the strongest strength, the lightest weight, the longest battery life and the deepest diving depth, which can reach 12 meters. Hope to adopt my answer.
