Thermal scopes and monocular’s are starting to change the way we work, they are very effective on rabbits in the right situation.
The white dots early on in the video below are rabbits out around 300 metres+ I’ve run the spotlight over this block a few times on my way past and hardly see a thing. The rabbits are on the neighbours (thankfully) but we try very hard to keep the rabbit proof boundary fence in top condition, that in itself is an ongoing mission.
