The unit is shockproof, I allowed myself a little typing on the screen, which is the part most exposed a priori, and no worries. Protection is thick enough.
The zoom is inside the box, so no risk he takes direct shock.
Immersion is not a problem for him, and the quality of photos and videos water is good. This is not a GoPro, certainly, but it allows to make nice shots.
The notice indicates, however, that should not exceed 2 hours of immersion under threat of infiltration.
Also tested at sea, rendering is good, even if we are far from DSLR.
It is compatible with SD cards (not supplied card, but one can store about twenty pictures with the internal memory).
So it's a very good price / quality ratio that is at the height of many other compacts.
