While on holiday in Hartenbos, Willie received an alarm call around 21h00 from Celmax, notifying him that someone was trying to steel his sheep in Brandfort.

After calling the farms caretaker and requesting him to investigate, he was told that although the sheep seemed restless, no-one could be seen in the area. One hour later Willie received another alarm call from Celmax. This time the farms caretaker reported that 220 sheep had gone missing. Willie called all the neighbours and police to help them in a search for the animals. The whole flock of sheep was later found 4km away. No thieves were caught, they all ran away. In the process the thieves cut through 4 camps border fences as they were driving the flock of sheep forward.

The next morning the farms caretaker came across the place near the sheep where the thieves were sitting and drinking beer while waiting for the perfect time. Willie’s words were: “If it wasn’t for the Celmax collars he would’ve lost 220 sheep”.

His sheep stays overnight in a camp near his house. One evening after it started to rain, he received alarm calls from his Celmax collar. Due to very cold conditions, Jan at first decided to ignore it but his wife eventually persuaded him to investigate.

When he got to the camp the sheep were not to be found in the spot where they usually sleep. After some time Jan did find some of the sheep, but realized it was only half of the flock. As he was searching further, he found the other sheep where two jackals were trying to isolate a sheep out of the flock.

Tony is situated near the town, where previously he had a loss of livestock due to stray dogs attacking his sheep as well as livestock theft.

His Celmax collar now warns him as soon as thieves or stray dogs try to chase his sheep. According to Tony he already shot more than 60 stray dogs. In the beginning he caught the thieves a few times while they were trying to steel his livestock.

The rumour quickly spread amongst the criminals that stealing from that farm is sure to get them caught. He now has very few incidents of livestock theft.


FarmRanger systems are in use in over 200 districts in South Africa, Namibia and Australia.
