I am an instructor for several agencies since 87. I've used many types of fins from different manufacturers and these are the best I've ever used in all types of kicks. I had to give it about two weeks to get used to them however. I've put all other fins away.
@@MartinSlisans Thank you for your reviews and information in your channel. I see that you live in Bali. I hope that I can make it there and dive with you. I wish you lots of success!!
My biases aside, I was interested to see the SP in action. Your back kick, it's pretty obvious why they aren't great, the angle of the blade is directing the water in a way that is working against you going backwards, only the part of the fin above where the blade breaks to the angle is doing anything, and that is not much surface area. The flutter stability (fin moves sideways when kicking and twists) also caught my attention, the vents are what is throwing it off I think. I would have designed some skegs atthe vents exit to impart stability basically to offset that if doing something along those lines. I think doing many dives using a flutter only that many divers will feel it in their ankles. That said, there is some neat features, and in some ways some solid design in play for them. As a cave instructor, and cave instructor trainer and evaluator I can say with absolute confidence that while back kicking is an essential skill for ALL cave divers, for cave instructors it's what we are doing for at least 50% of the dive if you are doing your job correctly and observing your students in a position to assist or intervene. I was actually a bit shocked at how good the Eddy's are at back kicking when I tried the first samples, and I designed them, so there is that. It exceeded my expectations.
I made about 70 dives with the s tek and love them. Because i have heavy legs, they tend to sink when i hover. The s tek has 2 detachable weights on both fins so in the mediteranean sea i use no weight on the fins and in the red sea just 1. With no weight the fins float, 1 weight make them neutral and 2 makes en sink. So i think for me they are perfect. Shake the sand from your socks and remove the weights, then judge again .
Thank you for the comment. Now it makes more sense for me why people choosing them. With or without weights on them it’s not an option for me, because they are narrow and not great for backwards moving compared with my another fins. For me it’s important since I do it a lot.
Thanks for this review, was considering them as a travel fin because they are light and the blades disattach, but I think I can skip them now... I hate sand in my socks 😅
Hi. Thank you! Gorilla fins are designed for flatter kick while I mostly dive using frog kick.But for holiday diver thinking this one is one of the progressive fins made. The fact that scubapro still produces and upgrades them says by itself.
I also own deep6 eddie. it's shorter, stiffer, lighter, it beats my Mares quattro with shitty bungees straps. if I have to say something I don't like about the deep6, it is the foot poket, I have to wear hard sole boots with them, unlike the Quattro, any boots would be good. on the other hand, Deep6 with soft boots just doesn't feel good. S-tek fins, they are the most ugly fins from Scubapro. If they made the jetfin detachable and light weight, it would be a bad ass.
Really interesting to see this, thank you. Can you clarify something you said at 7:00 - that the RK3 feel like you're not wearing fins as they're too soft and useless after using the Eddie's? Given it sounded like the RK3 were previously your favourite fins, it's a big shift! Can you confirm?
Thank you🙂 I mean the power Eddies gives is so much bigger than RK3 feels too soft when applying the same pressure to the blade it feels like you’re not moving. After some 5 mins I adapt to them and then all is good again. And this feeling I get every time I switch from Eddies to RK3. Don’t get me wrong RK3 is still one of my favorites, just this feeling. If you have the chance try, then it will be clear what I mean))
@@MartinSlisans I see, thank you for clarifying - have you tried the HD RK3? May be too negatively buoyant for your tastest though? And if I get the chance to try some Eddies I certainly will. The S-Tek were on my list to buy and try, but I'll remove them after your review and some thoughts from others too, primarily because of the issue of back kicking and the toe pressure.
Yeah, I tried HD RK3's. Yes they are stiffer but not the same as Eddies. Plus the weight is bigger. And the feet pocket is big and too loose for me since they are made for drysuit boots.

Great to hear from someone who really understand this fins. Like I said in my video, most probably I didn’t have enough time with them.

Just found a post where they say it's designed for diving professionals, but I don't think they will ever meet my needs. And I have Eddies:)

😄 I am sorry but that's how it felt for me.
Your review was entertaining and interesting. Thanks
Thank you 🙏
Hello thanks for your video, do you like the scubapro Gorilla nova please ?

Cool review... but guy in boxers on the back wasn't thrilled to be exposed like that 😅
My bad))) I saw it only filmed it and had no chance to film again. I apologized to him and he forgave ))
I love my apex fin...scubapro sucks
You mean Apeks RK3?
