The series used two Bell 206 Jetranger helicopters chartered from Castle Air. G-BHXU, piloted by Keith Thompson, was the main helicopter used by the Skyrunner and her entourage. A second helicopter, G-SPEY, piloted by Geoff Newman and later Michael Malric-Smith, shadowed BHXU as a communications aircraft. BHXU made later appearances in Interceptor (1989), among numerous other programmes, until a gearbox/rotor failure in 1995 forced it to ditch in the sea near Alderney in the Channel Islands. The pilot Michael Malric-Smith managed to escape unharmed.
Cameraman Graham Berry always wore a leather flying helmet when he was filming Treasure Hunt. This helmet, given to him by helicopter pilot Keith Thompson, contained earphones, a throat microphone and a radio transmitter/receiver so he could keep in contact with Keith, the communications helicopter and the studio.
This series was the production debut of aerial filming company Castle Air.
There was no visual link between the contestants in the studio and the Skyrunner - the only means of communication was via radio. The contestants had no idea what the Skyrunner was seeing (or often doing), or where she was going until the programme was televised. However, even the audio link wasn't always foolproof, and often broke up at inopportune moments, which added an unintentional difficulty factor to proceedings.
