GoPro is still considered the gold standard for action cams. They are not without issues though....and I will add any action cam you get will have issues at one time or another depending on how you are using it..with external power and or mic....how long will you be recording. All of them will get hot if recording long periods of time and shut down...freeze up. I have had a Hero 6.....7 and now a Hero 9. If you are going to use the Hero 7 with internal power and mic only you will be just fine. If you want to add external power and mic you to the Hero 7 you have to get the mic adapter. That is where the problems will show up. I have used mic adapters on all the GoPros I own....it has given me problems with all of them. With the Hero 9 I am using the media mod...external power...external mic...and so far all is fine. The Hero 7 is a good camera and I think you will be happy with it. My nephew uses the Hero 7 on his fishing trips stand alone and it works fine for him. Keep in mind I when I use my camera it is on for 4-6 hours straight.
