Nice image! I'm a big fan of Guillaume Nery, the french free diver (4 word records). Actually Constant weight divers are allowed to use fins (monofins most of the time), although they use it only to get to ~30m deep, after that point, the pressure is such that the volume of the body decreases and Archimedes thrust is no longer sufficient to compensate for the weight... so the diver can descend without any mouvement... It's very impressive to see (http://www.liveleak.com/view?i=d4a_1244462128).
Funny to read about this a few days after Guillaume Nery's accident: a line was set to the wrong depth causing the diverto dive to -139m/456ft instead of -129m/-423ft that he had announced the night before...
