TTRobotix introduces TTR-SB Seawolf submarine for GoPro cameras

“Even if they are half-murky, with a light things will be visible at short range, for instance close to the bottom.”

Virtually all underwater cases come with a light attachment.

“8 meter without a tank is definitely feasible but it will be a lot harder to keep the motion steady, not to mention maintaining it for more than a minute, than with this device. A lot, like.”

Except that you can do 1 minute every two minutes and go on for hours. While this thing only has a realistic 45-minute battery. So, again, when you factor in pros and cons, there really isn’t that much of a difference if you’re using this thing in shallow waters (and where does it say that all shallow waters are 8-meter deep?)
