pipedope:MOST of what we use in diving would be looked at as silly by somebody.
Why is a tank valve light more silly than a light stick?
Why is a force fin bad but a rocket fin is great?
Heck, diving those old twin hose regulators with small tanks made depth gages and pressure gages redundant. Wet suits and computers (including that Bottom timer that I would call the Un-computer) did not exist. Dry suits were used only by commercial hard hat divers.
The real definition of an absurd piece of equipment?
Any gear that I am not using that gives me the opportunity to make fun of someone else.
I just happened to be reading thru old stuff and thought this was a very well said post.
