Ok, I have a vague memory of a kids tv show, in the uk, where the main character was some kind of alien, who had been sent to earth to discover more about it, or something...He was staying with a lad whose name escapes me. All I can remember is that this alien guy wore an orange helmet, with an orange visor that slid down and scanned things. He also had some kind of wrist computer I think...
I've searched long and hard through lists of tv shows for this! ...Spark any memories?
