Go is easy to carry, but the imaging effect is not as good as Tg series. Generally, gopro is used when going up the mountain and Olympus is used when going out to sea. Never choose a dog when taking pictures. Dogs are sports and videos are absolutely awesome. I haven't played Gopro before, maybe I haven't mastered some skills, and the photos are not very good, but the shooting on land is still good, which reflects the advantage of wide angle. So, my advice to you is, if you haven't played Gopro, don't challenge it.
If you want to take pictures underwater, it is recommended that underwater drones, such as underwater photography robot fish, take pictures better.
