My professional roo-shooter mate in Central Qld uses one occasionally to find downed roos in long grass at night. They are often shot out to 200m or so, and by the time the vehicle is manouvered around trees, across gullies etc to the general area, they can be hard to find. He's had one for a couple of years now, so obviously an earlier model, but reckons it works well.

As for hunting, I've got enough stuff in my day-pack as it is!

"Gee, I wonder where that buffalo has gotten to? Better get out the 'sniffer' gadget and try to find it. Could it be behind that big grey thing over there...?"
