Split fins?

[Belce]

making some sort of contraption that moves the fins and measures force would be the only way to really settle this.

They did that, flipper crowd lost big time, they also tried it with humans and the flipper heads lost again, big time. No test examples of flippers beating split fins exist, is why no flipper head has posted any links to testing, none. Not here, not there, there is no emperical eveidence of flippers being better than fins other than some DIR wannabe singing to the choir.

It is a very different kick style required for fins as opposed to flippers and if you do not correctly use a fin kick style, but instead use styles more appropriate for flippers you won't get full benefit.

Sorry, I couldn't resist...

But also let this be a commentary on the absurdity of the "my fins can beat up your fins" topic.

That plain won't get anywhere if theres a head wind!

There is a very simple method for determing the best fins for technical diving applications. Simply research the fins worn by the best divers in the world such as Jarrod Jablonski, Casey McKinley, John Chatterton, etc. They would not be caught dead with split fins in their immediate vicinity. Recreational divers? Different story...

Welcome to a recreational diver forum, are you new here, perhaps you may want to take a very quick overview about recreational diving, its diferent.

First off, we respect what works for people, like what you are using, it does it for you, great.

And sceondly, I don`t really care what anyone in your list uses even for soap.

I don`t consider that Jarrod is a flipper user and not a fin user for diving important, he can go on using flippers, doesn`t change fins, truth is truth.

Ignorance is curable, willful ignorance is not.

A forum member posts a picture of a jet fin with multiple slots in it as a joke.....and that makes him willfully ignorant, in your view?

Dude, you should lighten up. It's kind of fun to bat the different ideas around, but at the end of the day they're just fins.......

....I didn't realize some people here took the split fin thing sooooo seriously.

I agree. I would not have responded to posts mentioning their limitations with tec diving had I known we were in the basic thread. I use 3 different style fins for various diving needs. Not a big fan of jet fins in open ocean singles diving...

Didn't say blades are split. Way back then there was single blade propeller (like screw type design) that showed less efficient than when "split" was introduced into the design producing modern multi-blade propeller.

Many boats have 3 blade propellers yet submarines end up with multiple blades. There is a reason for more "splits" between the blades.

I use blade fins because in my experience they offer more control. Speed/thrust is not everything when it comes to diving. But saying that putting splits makes them less efficient in thrust is far from understanding the dynamics of fluids.

Then perhaps divers should start using bigger air bladders in BCs to supply more lift so that they can spend more energy toward horizontal movement?

Sorry you've missed high school class discussing dynamics in fluids.

Iztok, the posts you are responding to are facetious.

Dude, I am big proponent of blade fins when it comes to control but just to provide no real feedback only to mock split is rather poor taste.

Ignorance that I was referring to is the lack of basic understanding of fluid dynamics. You know, basic high school knowledge. (Well at least if you went to high school other than in US, in US might be advanced college program, like algebra

Submarines have multiple blades to reduce their noise signature in the water and make them more difficult to detect.
