Depending on your upbringing, ‘fencing’ may mean something very different to you than other people.
If you’re very posh it’s the practice of non-lethally poking masked opponents with pointy sticks. If you’re slightly less posh, but still had a garden to run around in as a child, then it’s the practice of putting up a wooden division so that neighbours can’t just wander onto your property unsolicited.
And if you’re even less posh… it’s the practice of knowingly buying stolen property for the purpose of selling on at a later date.
I probably fall somewhere between the latter two.
However, perhaps you come from a long line of digital innovators and early adopters (your granddad developed the first beeper for instance) and the term fencing means more about GPS to you then anything else. If that’s the case then you probably needn’t read any further.
Then again you came this far…
