As a traveling diver I've been
carrying around a couple of Mini
C's for several years -- dependable,
not a lot of weight, don't take
up much space, and their beam is
adequate for most night diving. A
few months ago, I switched on Ikelite's new PCa. I've tested it in the pool
a couple time, and its size (fits easily in a small BC packet) and wide,
super-bright beam have won it a place in my gear bag on my next trip.
So I was not surprised when the managing editor of Britain's Diver  magazine named the PCa as his choice for best all-around performer. But
  I was puzzled by comments in the April issue of Rodale's Scuba Diving,
  which supposedly tested the PCa and three other small lights. The
  magazine grumbled about the clip mechanism for opening the case,
  saying that only divers with three hands would find it easy. I have only two
  hands, but I found battery access very easy. Rodale's also stated that the
  light was "nearly as bright as the Princeton Tech Mini Q40." Ikelite,
  holding that the light is brighter than its competitors', has strongly
  protested this finding, hypothesizing that they must have put the batteries
  in backwards. Despite these shortcomings, Rodale's still named the PCa as
  its Editor's Pick.  
I like the PCa's feel in the palm of my hand, its fit my BC pocket, and
  its beam. If it proves as dependable as my beat-up, taped-up Mini C's,
  then it's my pick too. I'll let you know.
