Review Tusa Hi-flex system, Tri-force blades

[lexvil]

You hit on a very good point- settling in with them. I know what I hate about my current fins, and that is their lack of stiffness. Now if these Deep 6 fins end up being too stiff then I will have new options to explore. I'm so new to scuba that I am learning what I like as I go. You can read forum posts until the cows come home, but individual preferences and individual body mechanics are a huge part of why people like or hate certain products.

When I was freediving a quarter century ago, I loved stiff fins even though they took some getting used to. I expect that these Eddys will require an adjustment. But I truly hate how my current fins flop and fold when I kick hard- because what I want is speed at those times. I have a rescue diver course coming up soon and I'm going to have to tow an "incapacitated" diver I guess- and I want fins that cooperate. As I've told "the boss"- this isn't about what I want- this is about saving lives!!!!!

This pair of Eddys will also be my very first fin that is not full-foot. This is what I just used for my open water and advanced open water in Cancun:

Seac F100 Pro Diving Fins

Perfect for dives in tropical waters, SEAC's F100 Pro fins are also ideal for snorkeling and spearfishing. Created for heavy-duty intensive use, the reliable and durable F100 Pro has a 25-degree blade inclination that provides optimal thrust without sideslipping for an excellent...

With or without thin athletic socks, these wore skin off my feet!! Fortunately I had packed plenty of waterproof bandages and could just cover up the hot spots. That's no way to live though!

I hope you have access to a pool or a swimming hole, do laps, laps,laps and more laps with these fins before the rescue corse, you will find muscles in your legs that you never knew you had.

The beauty of buying fins from Amazon and trying them is easy return since you can just drop them off.

You’ll find the Eddy FIN excels at frog kick and falls short in a flutter type kick for towing someone in the course, make sure you’re ready by doing laps, laps, laps

Roger that- and great minds think alike. I have a tab open to my local YMCA because they have a great pool!!!

OK, I just took my nephew swimming this afternoon to test these fins out. I did more than one hour of constant motion so I am sure I will be sore tomorrow! It was at a large pond at a local campground near my house. These monsters are definitely stiff and they produce a ton of power, which is exactly what I was looking for when I bought them.

The foot pocket on these fins is extremely comfortable. The only drawback is probably that if you don't like stiff fins or if you don't have a reasonably solid cardio base, they might be too much. We'll see how sore I am tomorrow and how many times in the water it takes to get used to these, but so far I am very impressed. Twenty-five years ago I traded in "normal" fins for freediving fins and that was a shock. Going from my latest Seac F100 to these was a shock as well, but not as bad as I remember with freediving fins that felt like they were 4x8 sheets of plywood strapped to my feet.

The genesis for this came from an earlier question posted a while ago, while looking into the fins in question I noticed an interesting (may not last) phenomenon in that if you ordered these fins in pieces from Bozo (Amazon) you can save about $100 over the cost of just buying the fins assembled.

Being a big fan of the scubapro super nova/ S tek fins I wanted to try these out and as a much less expensive to the SP take apart fins.
First to arrive were the screws and instructions, View attachment 876391
These were $7
Today the foot pockets, $49, blades $69 (I think I got them for $59) and spring straps $45 ($39 when I bought them) arrived.

Glad to see I am not the only person who dives in Chuck Taylors !!!!!

Lexvill, you did testing on my Aerohance Podshttps://aerohance.com/ and saw the results. Thank you for sharing this data. Now let's TRY FORCE FIN testing protocol on these fins. I must add an old concept developed by Cousteau and Aqua Lung in, 1960s. Snap together parts. The first pool test is to remove the strap and go kick. Tell us what happens. Then get some duck tape and place four-inch strips in the placement shown. Tell us the direction of flow on the down kick and up kick. Thank you.

Can you expand on this duct tape placement?

Can you expand on this duct tape placement?

Place duck tape and strings as my drawing shows. top side. In the middle and at the ends to show what direction the water is flowing. This method is used in Aviation. Hopefully, this makes things clear. Do the strap test first. It either flies or falls off.

Ah, got it I’ll give it a try

Did the string test as described and as I suspected and you already knew a flat stiffish blade will spill over the edge but by moving the strings closer to the design flow in the center they flow straight out the end on the down kick and straight away from the blade on the up or frog kick also as expected due to the blade design which also contributes to the power of the frog kick.
I know the force fin is designed for very smooth flow with low resistance and they excell at this, great in the use for quick point to point diving like the military does. I found force fins to work the bigger muscles at the front top of my legs more than blade fins do. I’ve never had the chance to try any of your other styles other than the pros so I can’t comment on them, always hoped to get my feet on some tan delta but…

Ok, did you remove the straps? That's the real test. do they fly or just fall off? A simple test for fin performance. Yes, water spills off to the sides with flat fin designs. One reason why I put my Whiskers on these poorly designed 1960 fin concepts. Simple kits for the placement of Force Fin winglet technology.

Thanks and have a great week.
