So, is it unfair to hold your dome underneath, say, a jellyfish on the surface and snap away? Is it unfair to use a rebreather because other divers have to deal with their bubbles? Is it unfair to take more than one frame?
I'm sorry to say that this reminds me of why I don't much like competitions (apart from not winning, that is....)!
What has any of these got to do with 'maybe' using a captive wolf in a contest that stipulates non captive subjects ... Although I do agree there's a certain advantage to using rebreathers over open circuit ...
