Binoculars and rangefinders can be used to spot animals from afar. When equipped and in aim mode (hold RMB/LT), an animal can be spotted via pressing E/the X-Button when directly looking at it.
Spotting an animal will reveal information about its gender and difficulty and will highlight the animal for a short period of time (its contours can be seen through obstacles). If the animal is currently using a need zone will automatically mark the need zone on the map.
The amount of revealed information can be increased by Skills.
