Hi,
I need to see what is happening in the cavity above my kitchen ceiling. I seem to have a damp patch and suspect a leak from the upstairs plumbin. Not far away I have some recessed lighting and wondered if a tool for viewing inaccesible places with a fibreoptic exists ? I could take out the bulb and use such a device to see what is going on without having to remove any ceiling stuff.
Kind of like the thing they make you swallow to examine your gut.
