Sort of like the thread about phasers that's been going for some time now. Let's see if we can catalogue all the tricorders from Star Trek, both screen-used and replica.
I'm not sure about all the variations and replicas out there (and I must admit, my TOS knowledge is a bit lacking), but here's a preliminary list of all the screen-used tricorder versions I can think of:
TOS tricorder
TMP tricorfer
WOK tricoder
Trek III-VI tricorder
TNG 1st Season Mark VI Science
TNG 1st Season Mark VI Medical
TNG 2nd/3rd Season Mark VI Medical (there was a different medical peripheral that appeared in later on--the one rodd.com sells)
TNG 3rd/4th Season Mark VI Science (the Ed Miarecki version)
TNG 3rd/4th Season Mark VI Medical (I'm not sure if this tric ever existed, but there were earlier versions that had the same graphic as the Mark VI's)
TNG Mark VII Science
TNG Mark VII Medical
FC Mark X Medical
Voyager Mark X Science
DS9 Mark IX Science (I get confused which was a Mark IX, somebody please correct me)
DS9 Weird tricorder variant (don't know what this is called, but it's that one with the big screen)
Nemesis Mark X
Nemesis tricorder (the flat one with the big screen)
