Insta 360 Go 2 is touted as "the world's smallest action camera". It can capture great 1440p action video at 50fps. The Go 2 has good stabilisation built in, although unfortunately this won't match the quality of stabilisation on the GoPro Hero 10.
A solid product, but not the best for paddleboarders who are likely to require a camera with longer battery life.
