Protective Housing for MISSION 1

The MISSION 1 is waterproof to 20 m (66 ft) without it, so this reads like an upsell until you have rinsed a camera after a week in the Red Sea. Salt does not care about a pressure rating. It creeps into the seal around a button, dries, crystallises, and the next dive is the one where the door does not close on a grain of it.

What you get for 60 dollars is a 60 m (196 ft) rating, a flat glass port that stays sharp above and below the surface, and a body you can hose down without thinking. The skeleton backdoor in the box swaps in when you want the sound and are not going in the water.

Flat port means the usual physics: everything looks a third bigger and a quarter closer than it is, and the corners of a wide frame soften. That is the trade every flat port makes, and on a 14 mm lens you will see it at the edges.
