My cousin wants to take pictures of himself with the massive fishes he catches, he usually fishes on his own.

He had some specs so I looked in the net and there were just too many cameras to go through and I got lost.

Would someone help me focus (no punn intended) please if I list what he wanted?

Dual/Flip around screen
Long battery life (he's out fishing for days)
Remote control
between about £300 to £400.

Thanks
