Force Fins VS the world (advice for first pair of fins?)

[Doby45]

Fins are reciprocating in a plane orthogonal to the direction of travel (roughly). Their mass has nothing (directly) to do with the force imparted to the diver.

The mass of the water pushed backward by the fins, times the acceleration of that water should be approximately equivalent to the force imparted to the diver.

Fin nerd with your fancy talkin.

No matter what the fin design is, the basic law of physics still applies: Force = Mass * Acceleration, and FF are just too lightweight. I have been taught well that it is best to minimize your body movement underwater. That's why I'll stick with jet fins. Scuba diving is not swimming, and you'll need to kick more frequent with FF to move around. So, it is up to your style and things you do underwater.

the weight of your fin has nothing to do with the force you can generate.
