The Captive Bolt device is used for safe and humane destruction of animals, from bobby calves to downer cows and pigs. A retracting bolt is fired into the brain of the animal, so the positioning of the device (as seen in pictures below) is very important. It must be between and slightly above the eyes to ensure the bolt hits the brain. Draw diagonal lines between the horns and the eyes and aim where the lines cross. It is also very important to hold the device hard against the head of the animal. This prevents damage to the device spring, and also ensures the bolt goes far enough into the brain. After two or three charges have been fired the gun will get hot. This is normal and if you have a few calves to destroy wearing gloves is recommended. After a number of activators are fired, they can become tight to remove. A knob at the end of the handle can be used to help remove the activator.

There are different strength cartridges for different-size animals. If too powerful a cartridge is used the captive bolt can become damaged (and may void the warranty). If the cartridge is too small the animal may not be killed. Refer to the activator chart below. Most dairy farmers will need the green activators for bobby calves, and the yellow activators for downer cows.
