Seller will take $155 for this set of Mediums.


A few people i know have really liked them, but a bit of mixed feedback i think? I saw Harrison Roach riding them briefly in one of his stab vids... didn't talk about the fins much as its mostly a review about boards. Starts at 6mins

H4s are the real McCOY!
More speed and drive than normal fins,its a NICE sensation.
Are they worth the 230bucks,YES!
They dont make a difference in weak waves like the H2s did,but get a bit of power behind them and its very noticeable.


If you put a ruler to the inside of the H4s, you'll notice a mistake: the manufacturing process causes the mold to cup and make an inside (concave) foil -not supposed to be be there, should be flat! The fins are made in a hockey stick factory, and therefore the manufacturing tolerances aren't so.. precise. Keep in mind, a 1mm inside foil (error) is equivalent to 1/3 of the thickness of the foil.
I'd be tempted to flatten the inside of the fin to see if it improves efficiency.


So FCS used Swiss Eng and Robotics and got a 1mm error....?

Here's a bit more about them

Hard not to notice the similarity of Mitchells ‘Switch Blades” that have been on the market a few years before the H4s. Shows that he is still ahead of the game after all these years. Made in Australia too

Switch Blades are nice looking fins but the only similarity is the Tip Shape ?


Seems like there is. Just watched the youtube link and looks like there’s more going on with the H4. The guy calls it “torsional flex” which ironically is how Mitchell describes his V stringers and flex tails


Can't really comment on the h4's as I haven't tried them. But think there's a bit of misinformation about "normal" fins flopping over in their flex. If they are foiled well and have a rigid base and made of good materials their flex characteristics should behave in a "torsional" manner. A lot of it is marketing guff delivered by an employee of the company. Realistic expectation would be a minimal percentage improvement in performance, in better waves, noticeable to high level ability surfers. So if you've got the money to throw at it, knock yourself out.




last thing I’d be spending money on. I’d be running for the shoulder in anything over 6 foot anyway


Yes Udo,save yourself 4 bucks on Amazon.


Flip lid, the switchblades look a bit like H4s but thats all,The performance is vastly different.


4 bucks ? or $66
FCS - $230 shipped
Amazon-$150 + $14.28 shipping- $164
Presuming the order price is in AuD ? havent used Amazon is that how it works ?


The amazon price is in USD
It says $208.78 + $19.88 shipping when I converted it to AUD on their site.


Ah yep i just clicked currency to AuD.


Nothing to do with the H4 fins but I just got an email from FCS about their collaboration with Leatherman tools.
18 tools it has, almost everything a surfer could need, as long as you don't need to screw in an FCS fin.
Including a 2mm Allen key, it does not.


What ?


You heard. No FCS key in an FCS collboration.

Reckon the small bit driver would be about the closest tool, but I'd end up frustrated and hack at it with the 420HC Serrated Knife.




A swiss Army knife @ Leica prices!
Back to the fins, $230 is a big ask for sure but the enhanced sensation is worth it in my opinion.
Quad sets wont be far away according to my source.


And for FCS 1 ? not available
So i have to trace lug positions from FCS1 onto H4s and spend 10 mins with a hacksaw..


FCS 1 is obsolete.(but I'll have to grubscrew in the Switchblades,see below)
So next decent swell I;ll be having the H4s up front and Switchblades as the trailing quads.
Scenario 1.. smallest Switchblades(double foiled)
Scenario 2... 2nd smallest Switchblades(single foil)
Scenario 3....a combination of the 2 different sized Switchblades.


Grubscrew the H4s as well eh ?


some people put a concave foil on the inside to improve performance. Hanalei have fins with a concave foil. The set they I have work well but an 'out there' shape and so don't know if it translates to a more std shaped fin


Cheers for the mention of the switchblades. That'll work with the FCS1 which certainly isn't obsolete in my quiver.
Udo I thought about the hacksaw as well (cleaned up with router) but can't bring myself to do it...


Cleaned up with a router....wtf for ?


Perfection. Satisfaction. OCD :)
Hello all , has anyone tried the H4 fcs fins ? I’ve seen reviews on you tube and read a few articles but just wanting to hear from someone that’s independent. The materials and finish looks first class but is it all just hype ? Expensive so they would want to be good and give something extra to warrant $229 retail.
