info: Henry Possum striker development – What it takes to kill a possum…
Possums are notoriously hard to despatch, as we can show you in the images below.
Just to build you a picture, the tip of the Henry automatic possum traps’ piston drives through the possums skull causing massive trauma to the brain. This renders the animal immediately and irreversibly unconscious. The first two images illustrate the type of damage which didn’t cause sufficient trauma even though accurate targeting was achieved.
The initial triford design had an outer diameter of 8mm, this accounts for nearly 1/3 the diameter of the brain casing, the next uses no blades and a solid striker.
For a consistent and effective kill, we use a piston 11mm diameter ( equivalent to a tea-cup diameter compared with the human) which expels the expanding gas into the cavity to further damage the delicate brain.
