Netgun Capture
This is a very specialized capture method used by only few game capture operators. This method is exclusively used for the capture of individual animals (trophy animals or specific sexes) were chemical immobilization would be too costly.
A specially built rifle is used and shoots out a 3m x 3m net that have led weights on the four corners. This method is used from out of a Helicopter and the pilot would try to get as close as possible to the animal and then the operator will shoot the net over the animal to capture the animal.
