In this picture, we see four men are standing and they are holding something in their hands. All of them are wearing the jackets and the caps. In front of them, we see a black box containing some equipment in it. On the left side, we see a white color box. They might be standing in the boat. In the background, we see water and this water might be in the lake. There are trees in the background. At the top, we see the sky.
