And, unless one is lucky, totally useless even in the hands of someone who has the equipment and the competence to operate it and interpret the results. As one might expect, the damage shown in this oft-posted piccie of mine passed an IR test with flying colours ...
We discussed this recently in relation to RF's scout hut, and it can be very difficult. The above illustrated damage was discovered (under floorboards) purely by accident, at a time when there was no known current or recent rodent problem, and may well have been there for years (although the copper does look pretty bright). I tested everything in the house (which, as above, proves nothing) and lifted a few floorboards in the vicinity (and found no other problem), but decided that the expose all the cables in my (verylarge) house would be impractical - and so relied on hope (and that way many years ago, with no known problems since)/
I agree - but, as above, in the knowledge that a full set of 'clean' tests in no way proves that there is not extensive damage to hidden cables.
Not foolproof! Once upon a time we had three cats, and that was the time when we had most mice (and other animals, including birds, even pigeons) in our house. The cats would often bring these creatures into the house alive, put them down proudly so we could see what they had caught, and then wondered why they ran off and hid under some piece of furniture (or flew around the kitchen!)!Maybe get a fierce version of this
Kind Regards, John
