As did the type 80 at Sopley, but when that went off for mx the 264 blip was wider than the Airway at range!
Nearly as good as the noddy height finders which gave you a height +/- 5,000ft.
Part of the famil for the T80 was to go into the cabin that went round with the head, without turning it off, to be shown "stuff" - can't imaging H&S allowing that nowadays.
