Want to learn about ForceFins, start reading here.
This is really a recap of lots of older post, combined into a single post and turned into a "sticky" for all of the divers, freedivers, snorkelers, etc... that want to have a consumers view of things. I have been lucky enough to use ForceFins for 10years now, and met Bob Evans(owner and designer of FF) a couple of years ago and encouraging me to try more and more of his fantastic designs.

Question:
ForceFin makes so many different fins and they are often hard to find in the local stores, how do I pick the right fin for me?

Answer: Forcefin makes many different fins because every diver is different and the wide selection allows each diver to fine tune his/her body, technique, expirience, strengths and weakness to find the best fin for YOU. Rest assured that all of the fins in the ForceFin line carry the same heritage of testing and refinement to make each as good as they can be for their intended purpose. Of course, they also share the trademark footpocket.

The Prime Line of fins are just that Prime. They are purpose designed for the recreational diver and meet the needs of technical and miltary divers around the globe. Just because ForceFin makes the Extra Line (Extra Force and Excellerating Force) they are not neccasarily better for you. The Extra Line are named appropriately, they are extra in every way, they are extra control, extra thrust, extra stable, but are extra expensive (sorry Bob, but they are, worth every cent, but still expensive).

So to pick the fin for you, lets start with your background. So answer the following questions
1) Are you (or have been) a competitive swimmer
2) How much do you dive?
3) Where do you dive? (ie currents, tropical, cold, penetration)

My basic recommendation for all Divers/swimmers new to the ForceFin line is to start with the basics; the Original or the slightly stiffer and more responsive Pro Fin. These 2 fins represent all of the characteristics of ForceFin and won't break the bank. Most divers find that one of these fins will do everything they want and don't need to buy more. If you are a competitive swimmer (or simply dive A LOT) the TanDelta maybe a better starting point for you.

All three of the Original Shaped fins will perform wonderfully, their differences lay not in the feel or strength to use them, but more in the kick frequency that you will use to go a given speed. The stiffer the material the slower your kick frequency will be. I have found that the ProForce is a great comprimise between flex and stiffness to allow me an optimum kick frequency and speed, giving me fantastic endurance to cover ground if I need to, but that being said, many people prefer the even lower frequency of the TanDelta as it also provides lots of low end torque. The stiffer materials will also allow greater speed, but of course greater speed requires more leg power, as no fin can overcome the friction of pushing you through the water, and if you remember physics: friction is proportional to the square of speed. So ulitmately your top speed will be more dependant on your legs than the fin, rest assured all of them compare favorably to even the best of the competition.

Of course don't forget the Original Split fin, named the Foil Force. This easy kicker will refresh your mind as you forget about kick and just enjoy the woderful mysteries of the underwater world. Its very easy to use, having a very similar feel to the Originals but with a lower kick frequency. I will say that although it moves quite well, it does not accelerate as well as the Original or the Pro even though the speed will be about the same. I believe this is due to the longer narrower blades.

Once you are fimiliar with the ForceFin Prime lines you may want to evaluate the Extra Line and the Adjustable line.
The Extra Line contains 2 of the best fins I have ever used; the Extra Force and the Excellerating Force

Both of these are absolutely incredible, but beware, incredible or not, they are a lot of fin, and they may be too much for many divers. You can see my previous dicussions on these here.

So that leaves the adjustable line. This is the most diverse line in the catalogue, but these are all pretty much specialist fins. If you need to change your bootie or go to a drysuit boot or go skin, this pocket will do it for you. In this line we have everything from the leg busting MultiForce for in pool workouts, Body boarding shredders RipForce, to the Fishermans friend the Float Tube Fin designed to allow the largest of Wader Boots to be securely held. The final fin to talk about is the Adjustable Force which looks similar to the Float Tube, but remember the Float tube has an oversized footpocket, this is the normal size and will fit dive booties and drysuit boots alike. The Adjustable has the advantage of fitting comfortably to any size boot and even barefoot, with the added advantage that you can add any of the ForceWings to the fin (see ForceWing Thread). Although ANY of the ForceFin line can have the Comfort Insteps added to reduce the size to fit your wetsuit booties. Which is my norm, I wear XXL fins with my Drysuit boot and slip the instep in to snug up the 3mm wetsuit bootie.

Military SD-1, I was able to convince Bob to sell me a pair of these about a year go, but he claims that he will put them on the market, so bug him and you "might" get a pair too. My first expirience with them was on the Boiler Wreck off Cape Hatterass. And of course there was a nice southern current, divable, but just barely. Of the 3 person dive group I was part of, I was the only one to make the 300yard surface swim onto the wreck, the other 2 were swept down current forcing me to abort, get them and make it back to shore, the others were wearing either Quattros and Bio-fins, but I digress. The next day we made it out diving in open water and I took them out again, this time I was really able to test them. Again a current, not as strong but over a knot and it was much weaker on the bottom. I found they manuever very easily, not to mention have enough speed to easily overcome the current. I found they performed flawlessly in positioning and sculling and the comfort of the footpocket is unmatched.
A side by side with the Pro, the Miltary lacks the distinctive snap and recovery feel of the pros, something I have always appreciated, but they out manuever the Pros. I also believe this is a fin that will convert many of the FF nay-sayers as it has a much more classic fin design and feel. If you swap diving wet and dry you will appreciate the great fit that you will get out of this fin in either boot

I did a series of runs counting the number of kicks to cover the pool in my nieghborhood
Pro Force Fins- 22
Foil Force- 22
Extra Force TanDelta w/whiskers parrallel- 20
Extra Force TanDelta w/whiskers in tight V- 17

Excellerator TanDelta
No ForceWings- 20
w/ Whiskers Parrallel- 19
w/ Batwings in any position- 18
w/ Whiskers in Tight V- 17

Based on the feel of the Excellerators and Extras. I have some additional comments-
1) shutter is very predominant without ForceWings, I do not recommend using this fin without one of them. disclaimer, this may not be as bad in the original polyurethanes
2) The Batwings are very flexible and adjusting them from the outside edge of the blade to a tight-V did not change the feel or distance per kick
3) Unlike the Extra Force, moving the whiskers to a tight-V did not change the feel of the Excellerator, but an improved DPK was noticed. Also unlike the Extra, speed did not seem to change, but I was not timing so this observation is purely anecdotal.
4) I found that I prerfered the Batwings on the Excellerators over all other configurations

Force Fin was the first to offer Variable Blade
Control and Variable Thrust Technology as an option to
your fins. Again all Bob thinks about is fins. Force
Fin and Bob Evans Designs presents you with the option
of four different types of Force Wings- they are
Batwings, Whiskers, Speed Pods and Sharks’ teeth. All
of these wings stabilize the blade of the fin, but it
is the option of creating less drag, improving thrust
and overall making your experience in the water more
efficient and controlled that makes the Force Wings a
smart choice.

Whiskers- Efficiency and Power
The most common in the Force Wings line up are the
Whiskers. This accessory is the one that the diver or
swimmer will notice the most and the quickest
underwater Force Wings
Besides the Bat Wings the remaining two (Sharks’ teeth and Speed
pods) are fine-tuning tools that act with water
dynamics in a more suttlle, but precise way.
.

Shark’s Teeth -Efficiency and Control
Shark’s Teeth help stabilize the blade and increases
tracking control. This Wing model is not intended for
variable thrust, but increased control. With activies
like body boarding and river boarding (white water
sledging) the Shark’s Teeth function like a keel on a
sailboat does. No rock and roll or wandering fin blade
with this baby attached to your fin.
Shark’s Teeth have another function that is shared
with the Speed Pods. Force Fin users with the Multi
Force, Rip Force and the Adjustable are using the
Shark’s Teeth turned perpendicular to the Fin and use
it as increased resistance for recovery and physical
conditioning. One customer described simply “ I have a
small pool so I turn the Teeth perpendicular to the
blade and now I have increased resistance for my
workouts and recovery for my legs”

Speed Pods –Efficiency and Speed
Speed Pods increase the surface area just enough to
break the surface tension in the same manner as the
Vortex generators on back of some of the Force Fin
Models Laws of Nature
It also focuses the water onto the
blade increasing the efficiency of the water moving
through the entire kick cycle. Speeds Pods are used by
swimmers, scuba divers, body boarders with a need for
more speed and more output from their input energy. In
the kick cycle water speeds up as it flows over the
curved hydrofoil shape and reduces drag, but there are
some Force Wing users who adjust the Force Wings just
to isolate or highlight strength or weaknesses in one
leg over the other for physical conditioning and
recovery therapy.

Bat Wings- Speed, Efficiency and Control Bat Wings
Everything out of the Force Wing Line up comes with
the Bat Wing and more. It is the biggest in size of
the Force Wing Family and it has two things that the
rest of wings do not have. Its position sits on top of
the Fin blade and the wing is flexible creating and
whole new water dynamic to improve sculling
underwater. When I worked in Fiji I had a dive master
who always used them and I can still see him hovering
over a group of tourist divers as they explore the
walls and reefs of Savusavu.
With the increase in surface area and the position on
the wings to the blade an increase in water volume is
accelerated behind you to aid in propulsion and thrust
and due to the flexibility of the wings, sculling
becomes easier and more efficient. This wing is not
for closed environment divers as mentioned before the
size of the Bat Wings is significant enough that you
would need a low profile wing as the Whisker or Speed
Pod if you were diving in really closed environments.

Force Wings is another great innovation in fin
technology that offers water enthusiasts a choice in
making precise adjustments with a flip of the wrist
that can’t be beat. Really like your fins, not a Force
Fin user, but interested in Force Wing Technology use
a launch pad kit force_wings
and you are able to adapt any
of the Force Wings to most of the fins on the market.
Force Wings allow you to take control and optimize the
way you want the water to work for you.
