I saw an underwater photography robot fish in the parent-child post bar and wanted to buy one to take my children to travel. Do you recommend a sea suitable for children?

Forget the robot fish. Why don't you go swimming by yourself? Parent-child travel doesn't need such high-tech gadgets. Buying an underwater camera or even a waterproof case of a mobile phone can almost achieve the purpose of taking pictures of the baby. Other equipment is not suitable for buying and playing by yourself. ...

If it helps, I hope to adopt it.
