2 weeks ago, my assistant instructor asked me to try her Mares fins. You know, the $189 fins. I gave her my Quattros. We gently finned down the pool. She kicked my ass with my fins. We tried again going harder. She kicked my ass again. All this in a 20 yard pool. It was not even close! I like Mares gear, but these fins are not for me, and I cannot see any experienced diver using them. At that point I decided, my feet will never be in Volo fins again, just like my ass will never be in a Southwest Airlines seat again. H.

They seem more than able to replace the out of production Mares Plana Plus. While this may seem a big recommendation, its appliance to technical diving may just be a typical case of violation of model theory. Latter predicts certain thoughts before doing a comparison. In this case these thoughts center around scaling, streamlining, mass inertia, front area, vortices etc. Plainly, what's good for the goose, must not be good for the gander. In other words, a speedboat has a different propeller than an icebreaker, a mackerel (fast moving fish)other fins than a sunfish( slow). Tec-Divers are slow moving fish. And, other than for propulsion only, you need the fin for stabilizing, so you want a good strong blade with a well defined surface area.
