These dual mount arms make it super easy to get different views from one location. I usually angle the top one towards the center of the bow and the bottom one over the top cap to record the fish jumping and fighting it's way over the boat. I run power to each gopro to keep it running all day. Over the years I've changed from recording the entire day, to just using 5 minute looping now so after each fish catch or important event it saves the last 5 minutes. With high quality footage, this allows you to fit most of your key events on one sd micro card. During the hot months, I'll record in a lower resolution and frame rate to keep the cameras from over heating. If you are trying to record 4k in 60fps, that definitely heats up the camera. Throw in some 90 degree sun shining down and you will have issues.
