There I was at a drainage exhibition looking at what I think would become next years must have toy for kids… if they knew they existed! CCTV drain cameras are pretty cool things, the ones on show had big 4×4 type wheels, lights and of course a camera. Great fun. This little cheap & cheerful one is all I could find on the internet to demonstrate what i’m talking about… you should get the idea however. I didn’t enquire as to the price of an all-singing-all-dancing one but the “economy crawler” i’ve linked to is £15,500.
