Hmmm, let's see.
In 1968, Rule was something is better than nothing:
Mask, Voit oval
Fins, Voit Super Viking
BC, what is that??????? huh, a bag full of air you say, is this a joke!
SPG, nope, had a J valve
Knife, USD Sea Hawk
Computer, what is that? watch, depth gauge, compass
Regulator, USD Mistral or USD Calypso
DSMB, huh?
Camera, Kodak in a plastic box I made
Now some 53 years later 2021, Rule is less is more:
Mask prescription Atomic Frameless or Scubapro Frameless
Fins, Avanti Quattro, Eddy Fins, SP Go Sports (I am a fin-aholic in recovery)
BC, VDH plate with VDH 22# wing, Oxy UL plate with Oxy 18, Freedom Plate with Oxy 30
SPG, 1.5 inch B&P
Knife, Tekna titanium and some sort of line cutter thing
Computer, Shearwater Peregrine as main unit
Regulator, VDH Argonaut Kraken, AL Titan LX Supreme
DSMB, I keep buying spools and DSMBs and so far have not found one I am satisfied with
Camera, Nauticam NA6400
And no, I am not AI because it violates my guiding principle:
