If you intend to find and identify wild boar over larger distances (up to 1500m) in open country, you should maybe try a device with higher resolution (640 x 480). We used a Pulsar Helion XP50 in our project to spot wild boar at night and found it very useful for a quick overview. At a distance of 50m, you're going to see details as thin as hair. Video shooting is also possible, as well as screen sharing via WiFi, e.g. with a smart phone.
