Thieves have stolen 4 of our electric fence units

[ahlam1399]

and their batteries...So, ideas to prevent them nicking the replacements?Can use old units, but they're not in use for the reason they are a bit temperamental and sometimes decide not to 'tick'. Batteries much the same.What do others do?
