It hasn’t been that many years
since you could look around a
dive boat between dives and see
divers who were wracking their
brains, desperately trying to recall
how to work surface intervals into
repetitive nitrogen times. They
didn’t want to let on, of course,
that they didn’t have a clue about
how to go about it, but they were
easily recognizable by their
hunched positions as they bent
over their tiny plastic tables,
praying for inspiration.
Then, in 1983, Orca Industries
  introduced the Edge, and
  multilevel diving and dive computers
  were in. I jumped on the
  bandwagon immediately. Sure,
  the unit had a few weak links: the
  battery compartment flooded too
  often and it ate 9-volt batteries the
  way a kid eats candy, but it was
  easy to use, and the increased
  bottom time made the $675 price
  tag look reasonable. Hell, it was
  more than reasonable: it was
  wonderful. It changed diving.  
Within a few years of the
  Edge’s introduction, technological
  developments and a multitude
  of other manufacturers reduced
  dive computers’ size from the
  Edge’s hefty 1.6 pounds down to
  wrist models and console inserts.
  The reduction prompted some
  sardonic postings on online scuba
  groups suggesting “One Hundred
  Things to Do with the Brick
  (Edge).”  
Orca developed a smaller,
  cheaper version, the Skinny
  Dipper, which was plagued by
  battery problems, then pioneered
  the Delphi, an air-integrated unit.
  Unfortunately, early editions of
  the Delphi had some problems
  with the high-pressure sensors that undercut its marketability.
EIT, Inc., an electronics firm
  based in Virginia, bought Orca in
  the early nineties and retooled
  the Skinny Dipper into the
  Marathon and the Delphi into the
  Phoenix. They dropped production
  of the Edge although they
  continued to service the units. In
  recent years they added the Pilot,
  a line of dive computers manufactured
  for them in Finland.  
Now, however, it sounds like
  EIT has discovered what most of
  us already knew: the best way to
  make a small fortune in the dive
  business is to start with a large
  one. The company’s made a
  bottom-line decision to effectively
  get out of the scuba market and
  concentrate its efforts in the
  industrial electronics sector.  
My hat is off to Karl Huggins,
  Craig Barshinger, and all of the
  others who were involved in
  developing and bringing the
  original Edge to market. Your
  development marked a turning
  point in dive technology, one that revolutionized the way most of us
dive today. It’s a testimonial to you
that I could sell my Edge today for
more than I paid for it 16 years
ago. Commercial divers who
believe in its tested algorithms
and appreciate its large display
will pay top dollar if they find
someone willing to let go of their
brick. Sorry to disappoint them,
but I’m hanging on to mine to the
bitter end, which doesn’t seem to
be that far away.
