Hand held scanners

Geiger Counter

Breakaway: the Geiger counter. A wand is inserted into the synthocrete nuclear waste cap and the counter displays a reading with a scale of lights. The scanner reappears in Earthbound and as a medical scanner in Mark Of Archanon.

Earthbound: the Geiger counter reappears in orange with an attached wand.

In Mark Of Archanon it is in the TechLab 3.

It is just visible on the planet in The Immunity Syndrome (on the table, behind Alibe's head).

Spectro-X Scanner

Earthbound: Victor's clicky scanner (supplying data for the Spectro-X analysis made by Kano?). The prop is made from a 1971 Braun HLD 6/61 hair-dryer, designed by Jurgen Greubel.

Drill

Earthbound: Helena's drill is a battery-powered Kenwood hand mixer with a very long drill bit. Kenwood is a leading UK kitchen appliance company, and many of their products in the 1970s were designed by Kenneth Grange of the Pentagram design consultancy. Although cordless power drills existed at the time (invented by Black and Decker in 1961), they were expensive and marketed only to industry. The first widely available portable drill was from Makita in 1978.

Water analyser

A water analyser seen in Matter Of Life And Death. It is also seen in The Testament Of Arkadia (in the Arkadia cave held by Anna). The water analyser is seen again (alongside Helena's drill from Earthbound and the organitron).

Organitron

The Organitron is a calculator-like instrument used by Koenig in Guardian Of Piri (it is named in the script, and the name is written on the end in the green label). It is also used by Victor in other episodes including The Testament Of Arkadia. It is also seen in The Exiles

Victor's scanner from The Troubled Spirit

Heat sensor

A commlock-like heat sensor is seen in Force Of Life

It is a prop from The Protectors 2-part episode "WAM" (1973). In that episode it was a walkie-talkie, used by guest stars Prentis Hancock and Jill Townsend. Another guest star, Michael Sheard is aiding the series stars, and also gets to handle one. Thanks to Chris Bentley in the book Space: 1999 The Vault (2022).

Signal locator

Victor's scanner in Death's Other Dominion

Signal locator 2

Seen in The Full Circle, this scanner is used to locate radio markers on the alien planet. The prop (a Dictaphone microphone) is also used in All That Glisters, and is seen as a alien weapon in Mission Of The Darians and A Matter Of Balance

General purpose scanner

From The Exiles Maya and others use this scanner with a parabolic antenna (actually photographic flash guns - see the sketched plans). There were very similar versions of the same prop. They are featured in The Exiles, The Mark Of Archanon, The AB Chrysalis, The Rules Of Luton, A Matter Of Balance & The Immunity Syndrome.
