It provides a matchbox sized digital camera with backplate LCD screen and so-so 14MP stills and 4K video.
Falling somewhere in between these options is the small yet outwardly robust SeaLife ReefMaster RM-4K.
To use the camera in water you have to secure it inside the provided rubber-sealed, screw-fastened plastic housing.

While this doesnt make for the fastest or most responsive of setups, it works.
The price is comparable to that of a toughened, waterproofed point-and-shoot camera.
So far so intuitive.
Essentially its a case of pointing the camera, pressing the button, and hoping for the best.
Should I buy the SeaLife ReefMaster RM-4K?
It also demonstrated that its best to configure shooting tweaks in advance, rather than in the moment.
